Air Circuit Breaker Price List 2024 by Brand and Rating Guide
What is an air circuit breaker price list? An air circuit breaker price list is a structured reference cataloguing ACB unit costs by brand, current rating (400–6300 A), breaking capacity (Icu), and frame size under IEC 60947-2, enabling procurement teams to benchmark capital expenditure across tier-1 and tier-2 manufacturers. Selecting on unit price alone — without accounting for Icu/Ics ratios, LSIG trip unit configuration, or spare-parts availability — routinely inflates total cost of ownership through premature failure, unplanned downtime, or non-compliant installations. This guide covers the primary drivers of ACB pricing, a brand-and-rating price comparison, correct ampere rating calculation methodology, total cost of ownership analysis, application-specific pricing for data centers, hospitals, and industrial plants, and counterfeit or grey-market risk mitigation.
What Drives Air Circuit Breaker Pricing in?
Before any price list is useful, you have to understand what you are actually paying for. An ACB list price is not a single number — it is a stack of components, and each one has moved differently in the past 18 months.
In our experience handling tenders across European and Gulf utilities, four cost drivers explain almost every price gap between two seemingly identical ACBs:
1. Frame Size and Rated Current (Iₙ)
Frame size is the single largest variable. An ABB Emax 2 E1.2 frame (up to 1600A) sits in a different cost band than an E2.2 (up to 2500A) or E4.2 (up to 4000A). Doubling rated current does not double the price — it typically increases it by 35–55% because the silver-tungsten contacts, arc chutes, and main current path must be uprated, but the operating mechanism and trip unit electronics stay similar.
2. Trip Unit Intelligence
This is where engineers often overlook real money. A basic Ekip Dip LI (long-time + instantaneous) trip unit is roughly 40% cheaper than an Ekip Touch LSIG (with short-time, ground fault, and measuring functions). For a non-critical motor feeder, LI is fine. For a data center main, you almost always need LSIG with selectivity coordination.
3. Breaking Capacity (Icu / Ics)
Per IEC 60947-2 Clause 4.3.5.2, Icu is the ultimate short-circuit breaking capacity, while Ics is the service breaking capacity (the current the breaker can interrupt and still remain serviceable). A 42kA-rated ACB and a 65kA-rated ACB of the same frame can differ by 18–25% in price. Specify what your fault level actually demands — not a round number that "feels safe."
4. Execution: Fixed vs. Drawout (F vs. W)
Drawout (withdrawable) versions cost 30–45% more than fixed-mounted, but they cut Mean Time To Repair (MTTR) from hours to minutes. For a 24/7 plant, the drawout premium pays itself back on the first maintenance cycle.
2024 Air Circuit Breaker Price List by Brand and Rating
The figures below reflect indicative list pricing in EUR for European-sourced units, three-pole, 415V Ue, drawout execution where noted, with a basic LI electronic trip unit. Actual project pricing typically lands 25–55% below list depending on volume, distributor agreement, and configuration. These are reference benchmarks — not quotations.
ABB Emax 2 Series
| Model / SKU | Rated Current Iₙ | Icu @ 415V | List Price (EUR, indicative) |
|---|---|---|---|
| ABB 1SDA070701R1 E1.2B 630 LI | 630 A | 42 kA | €2,950 |
| ABB 1SDA070741R1 E1.2B 800 LI | 800 A | 42 kA | €3,180 |
| ABB 1SDA070781R1 E1.2B 1000 LI | 1000 A | 42 kA | €3,420 |
| ABB 1SDA070821R1 E1.2B 1250 LI | 1250 A | 42 kA | €3,790 |
| ABB 1SDA070861R1 E1.2B 1600 LI | 1600 A | 42 kA | €4,180 |
| ABB 1SDA070981R1 E2.2B 1600 LI HR | 1600 A | 42 kA | €5,640 |
| ABB 1SDA071021R1 E2.2B 2000 LI HR | 2000 A | 42 kA | €6,290 |
Note that the same E1.2 frame jumping from a 630A to a 1600A unit only adds about €1,230 — that is the "frame economics" lesson most procurement teams miss. If you expect load growth above 70% within five years, buy the larger frame now and de-rate; the marginal cost is small.
Schneider Electric MasterPact MTZ
| Model | Rated Current | Icu @ 415V | List Price (EUR, indicative) |
|---|---|---|---|
| MasterPact MTZ1 06 H1 Micrologic 2.0X | 630 A | 42 kA | €3,080 |
| MasterPact MTZ1 10 H1 | 1000 A | 42 kA | €3,510 |
| MasterPact MTZ1 16 H1 | 1600 A | 42 kA | €4,290 |
| MasterPact MTZ2 25 H1 | 2500 A | 66 kA | €8,650 |
| MasterPact MTZ2 40 H1 | 4000 A | 66 kA | €13,200 |
Siemens 3WL / 3WT
| Model | Rated Current | Icu @ 415V | List Price (EUR, indicative) |
|---|---|---|---|
| Siemens 3WL1106 ETU37W | 630 A | 42 kA | €2,890 |
| Siemens 3WL1110 ETU37W | 1000 A | 42 kA | €3,340 |
| Siemens 3WL1116 ETU37W | 1600 A | 50 kA | €4,070 |
| Siemens 3WL1225 ETU45B | 2500 A | 66 kA | €8,420 |
| Siemens 3WL1340 ETU45B | 4000 A | 80 kA | €13,950 |

How Do You Calculate the Right ACB Rating Without Overpaying?
A common mistake we see in tender specifications: the engineer takes the transformer secondary current, multiplies by 1.25, rounds up to the next breaker frame, and calls it done. That works — and it overspends about 15% of the time, because rated current selection per IEC 60947-2 must consider continuous duty derating, ambient temperature, and the harmonic spectrum of the load.
The minimum ACB rated current for a continuous load is governed by:
Formula: Minimum ACB Rated Current — Source: IEC 60947-2 §7.2.1.1 / IEEE Std 242 Buff Book
In,min = (IL × kh) / (kt × ka)
| Symbol | Description | Unit |
|---|---|---|
| In,min | Minimum required rated current of the ACB | A |
| IL | Continuous load current (RMS) | A |
| kh | Harmonic derating factor (1.0 for linear loads, up to 1.4 for VFD-heavy loads) | — |
| kt | Temperature correction factor (0.85–1.0 for 40–55°C ambient) | — |
| ka | Altitude correction factor (1.0 below 2000m, 0.92 at 3000m) | — |

Total Cost of Ownership: Why the Cheapest ACB Often Costs More
In practice, the unit price is maybe 60% of the lifetime cost of an ACB in a critical installation. The rest is installation, commissioning, spare parts, and — most painfully — downtime when something trips and nobody knows why.
Consider a real example: a pharmaceutical manufacturing site in northern Italy, 3MVA transformer, 4000A main ACB. The procurement team saved €3,200 by selecting a basic LI trip unit instead of LSIG with measurement. Three months in, an unexplained trip took the cleanroom HVAC offline for 6 hours. With no event log, no waveform capture, the root cause investigation took two engineers four days. Cost of the saved €3,200? Approximately €180,000 in batch losses and contamination risk.
This is exactly the scenario covered in our analysis of ACB nuisance tripping causes and fixes — and the fix almost always starts with a trip unit that records the event.
The TCO Components You Should Budget For
For a 1600A class ACB over a 25-year life:
- Initial purchase: €4,000–6,000
- Installation labor and commissioning: €800–1,500
- Preventive maintenance every 5 years (contact inspection, mechanism lubrication, ETU calibration): €400–700 per visit
- One major overhaul or contact replacement at year 15: €1,200–2,500
- Risk-adjusted downtime cost: highly facility-dependent
Application Pricing: Data Centers, Hospitals, and Industrial Plants
ACB pricing is also context-driven. The same 2500A breaker bought for a steel mill costs differently from one specified into a Tier III data center, because the spec sheet is different.
Data Centers
Data centers typically demand 100% Icu = Ics rating, full selectivity (per IEC 60947-2 Annex A), neutral protection on TN-S systems, and dual-source synchronization capability. Expect a 20–30% premium over baseline pricing. Our deeper note on ACB selection for data centers covers the design specifics.
Hospitals (per IEC 60364-7-710)
Group 2 medical locations require enhanced earth fault protection and certified test schedules. Expect modest premium (5–10%) but significant documentation overhead.
Heavy Industry
Cement, steel, mining: high ambient temperature (up to 55°C), conductive dust, vibration. Often justifies an upgraded enclosure rating and HR (high-rating) frame designation, like the E2.2B 1600 HR or 2000 HR variants.
What About Counterfeits and Grey Market ACBs?
Some engineers argue that price gaps of 60%+ on the same SKU just mean "good distributor relationships." In my experience, that is wishful thinking past a certain threshold. If you are seeing an ABB E2.2B 2000 quoted at €2,800 when the list is €6,290, you are almost certainly looking at one of three things: a refurbished unit sold as new, a parallel-import (grey market) unit without local warranty, or — worse — a counterfeit with non-original arc chutes.
The IEC 60947-2 type-test certificate is non-transferable. A counterfeit may pass a no-load operation test and still fail catastrophically at 30kA prospective fault. We have seen the metallurgical reports.

Frequently Asked Questions
Why does the same ACB SKU vary somuch in price between distributors?
Distributor pricing reflects volume agreements, regional stock availability, included accessories, and warranty terms. A unit listed at €4,180 by one source and €3,100 by another may differ in factory build year, included motor operator, communication module, or auxiliary contacts. Always compare like-for-like configuration codes, not just the base SKU.
What is the typical lead time for an ACB in?
For standard configurations from ABB, Schneider, and Siemens, expect 6–10 weeks ex-works in Q3/Q4. Stock items at established distributors ship in days. Configured units with non-standard trip units, special voltages, or accessory kits can extend to 14–18 weeks. Plan procurement accordingly for greenfield projects.
Should I buy a fixed or drawout ACB?
For any application where downtime exceeds €5,000 per hour, choose drawout. The 30–45% cost premium is repaid the first time you need to inspect contacts, replace a trip unit, or perform the 5-year preventive maintenance per the manufacturer's schedule. Fixed-pattern ACBs make sense only for non-critical feeders or budget-constrained secondary distribution.
Is the breaking capacity Icu always equal to Ics?
No, and this matters. Per IEC 60947-2 §4.3.5.2.4, Ics may be specified at 50%, 75%, or 100% of Icu. Cheaper utility-class ACBs may show Ics = 50% Icu, meaning after one full short-circuit interruption the unit needs replacement. For data centers, hospitals, and critical industrial mains, specify Ics = 100% Icu — and confirm it on the nameplate, not just the catalog. See our IEC 60947-2 standard breakdown for the full clause reference.
Can I retrofit an old ACB with a modern electronic trip unit?
Sometimes. ABB, Schneider, and Siemens all offer retrofit kits for previous-generation frames (Emax 1 to Emax 2 trip unit upgrade, for example), but cross-brand retrofits are not supported and would void IEC 60947-2 type-test compliance. The economics rarely favor retrofitting beyond 15 years of service — at that point, full replacement with a current-generation unit usually wins on TCO.
How often should an ACB be maintained?
Per most manufacturer guidance aligned with IEC 60947-2 service requirements, plan a visual inspection annually, a functional test every 3 years, and a full mechanical and electrical overhaul every 5–7 years or after a significant fault interruption. Trip units should be calibration-checked at the same intervals. Track the operations counter — most ACBs are rated for 10,000 mechanical and 1,500–3,000 electrical operations at rated current.
Are ABB Emax 2 and Schneider MasterPact MTZ interchangeable?
Mechanically and electrically, no — the cassette dimensions, secondary terminal arrangements, and accessory ecosystems are proprietary. Functionally, they are equivalent for most applications. Switching brands mid-project usually means re-engineering the switchgear cubicle. For a feature-by-feature comparison, see our ABB vs Schneider vs Siemens ACB analysis.
Conclusion: Buying ACBs Intelligently in
Air circuit breaker pricing in rewards engineers who specify precisely and punishes those who copy-paste old specifications. The biggest savings come not from chasing the lowest unit price but from right-sizing the frame, matching trip unit intelligence to the actual application, and avoiding the false economy of underspecified breaking capacity. A €3,000 saving on the wrong ACB can become a €300,000 problem the first time a fault clears improperly.
For procurement managers building capital plans, the practical rule is straightforward: anchor your budget on indicative list pricing, apply realistic distributor discounts (25–55% depending on volume), and leave 8–12% headroom for trip unit upgrades that will pay back through diagnostics. For consulting engineers, write specifications that cite IEC 60947-2 clauses explicitly, demand Ics = 100% Icu on critical mains, and require type-test certificates with every quote.
For the complete selection methodology — including selectivity coordination, neutral protection, and integration with downstream protection devices — see our full Air Circuit Breaker engineering guide. And when you are ready to specify a current-production unit, the ABB Emax 2 catalog from 630A E1.2B through 2000A E2.2B HR covers the great majority of low-voltage main distribution applications encountered in industrial and commercial projects today.
