Schneider Acti9 iC60 vs Easy9: Which Schneider MCB

What separates Schneider's Acti9 iC60 from Easy9? Both are Schneider Electric miniature circuit breakers built to IEC 60898-1, but iC60 covers a wider breaking-capacity range (6-10 kA and up, with higher-rated variants beyond that) and Easy9 sits at 4.5-6 kA for residential final circuits. The gap matters at spec time: iC60 carries an add-on RCBO module (Vigi), comb busbar compatibility, and a broader curve/current spread, while Easy9 is a fixed-scope line for straightforward domestic boards. This article covers breaking capacity, curve coverage, the accessory ecosystem, standards scope, and where each line actually belongs on a job.

What Actually Separates iC60 from Easy9

Both ranges trip on the same physics: a bimetal strip for overload, a solenoid for short-circuit. What differs is the envelope Schneider engineers around that core. iC60 is built as a modular platform — same base breaker, but with add-on RCD blocks, auxiliary contacts, shunt trips, and comb busbar systems layered on top. Easy9 is a closed catalog: MCB, and in some markets a residual-current add-on, with a shorter accessory list.

The distinction shows up first on the breaking-capacity nameplate. iC60N carries 6 kA (up to 10 kA on some 60898 references), iC60H moves into the 10-15 kA band, and iC60L is current-limiting, rated up to roughly 25 kA on some 15 kA-class references. Easy9 does not go past 6 kA. For a residential consumer unit fed from a small transformer, that's often enough. For a board closer to a distribution transformer, it usually is not.

Breaking Capacity: 6-10 kA+ vs 4.5-6 kA

Breaking capacity (Icn) is the maximum short-circuit current the MCB can interrupt without damage, at the rated voltage. It's not a performance figure you can round up. If the prospective fault current at the point of installation exceeds the breaker's Icn, the MCB can fail to clear the fault safely — welded contacts, case rupture, or fire risk depending on severity.

Easy9's 4.5-6 kA range covers most single-family dwellings supplied a reasonable distance from the transformer. iC60N's 6-10 kA range covers the same ground with more margin, and iC60H/iC60L push into territory that matters for boards near substations, industrial risers, or generator-backed supplies where fault levels run higher. What we see in the field: panel builders quoting commercial fit-outs default to iC60 without checking the actual fault level, paying for headroom the site doesn't need. The inverse mistake — Easy9 on a board that needed 10 kA — is the more expensive one to fix after the fact.

Curve Coverage and Current Ratings

iC60 spans B, C, and D curves as standard, with K and Z available on selected references for electronic-load and motor-heavy applications. Ratings run 0.5-63 A across 1P, 2P, 3P, 4P, and 1P+N configurations. Easy9 is narrower: mainly B and C curve, sized for lighting, socket, and small-appliance circuits rather than motor starting or capacitor banks.

This curve gap tracks the breaking-capacity gap for a reason — D, K, and Z curve applications tend to sit on boards with higher fault levels anyway (motor control centers, workshop supplies, generator circuits), so Schneider pairs the wider curve set with the higher-breaking-capacity line rather than splitting them across ranges.

The RCBO and Accessory Ecosystem

Vigi iC60 is the add-on residual-current block that converts a standard iC60 MCB into an RCBO — overload, short-circuit, and earth-leakage protection in one assembly, without swapping the base breaker. iC60 also takes comb busbars for fast multi-way wiring, auxiliary and alarm contacts for remote status, and shunt-trip or undervoltage releases for centralized shutdown. That's the accessory depth a panel builder needs when a board has monitoring, remote trip, or selective earth-leakage requirements across multiple circuits.

Easy9's accessory list is shorter by design — it's a residential line, and residential boards rarely need auxiliary contacts or shunt trips on every way. Where an RCBO function is required on Easy9, the option set is narrower than iC60's Vigi range, and comb busbar support is limited compared to iC60's modular system.

Standards Scope and Where Each Line Applies

Both lines are built to IEC 60898-1, the standard covering MCBs for household and similar installations operated by ordinary persons, with Icn expressed directly in amps (6000 A, 10000 A, and so on). iC60's higher-tier references also carry IEC 60947-2 ratings (Icu/Ics), the industrial standard that assumes skilled operation and permits the K and Z curves. Easy9 stays within the 60898-1 household scope — it is not positioned as an industrial breaker, and does not carry the dual-marking iC60H and iC60L do on select references.

For a project spanning both a domestic distribution board and an industrial control panel, this split can mean specifying iC60 across the board just to keep one line and one spares inventory, even where Easy9 would technically clear the domestic circuits.

When Easy9 Is the Right Call

Easy9 fits new-build apartments, small retail units, and residential rewires where the supply is a standard household connection, circuits are lighting, socket outlets, and small appliances, and the fault level at the board sits comfortably under 6 kA. The line costs less per way, and for a job with 20+ ways on a domestic board, that difference compounds. If the specification calls for a straightforward B or C curve MCB with no auxiliary contacts, no Vigi RCBO, and no comb busbar requirement, Easy9 clears the job without any functional shortfall.

Where Easy9 does not fit: any board where the design fault current is unconfirmed or known to run above 6 kA, any circuit needing D, K, or Z curve, and any panel where remote monitoring or shunt-trip control is part of the spec.

When iC60 Is Worth the Difference in Cost

iC60 earns its price on three grounds: higher breaking capacity for boards with confirmed fault levels above Easy9's ceiling, curve coverage for motor and electronic loads that Easy9 doesn't offer, and an accessory ecosystem (Vigi, comb busbars, auxiliary/alarm contacts, shunt trips) that Easy9 doesn't carry at all. Commercial and light-industrial panels, boards near transformers or generators, and any installation with individual-way monitoring requirements sit squarely in iC60 territory. This depends on the load and the fault level at the specific point of installation — a blanket "always use iC60" policy on a purely residential job spends money the site doesn't need, just as defaulting to Easy9 on a commercial board risks specifying below the required breaking capacity.

For background on how breaking-capacity classes translate into board-level decisions, see MCB breaking capacity 3kA, 6kA and 10kA explained. To confirm curve selection against the connected load, check how to choose the right MCB tripping curve. If earth-leakage protection is part of the spec, MCB vs RCBO vs RCD vs RCCB differences covers where Vigi-style add-ons fit. And where the choice sits between household and industrial rating, IEC 60898-1 vs IEC 60947-2 standards compared lays out the scope split referenced above.

Both lines fall under Schneider's broader miniature circuit breakers range, and sit alongside the wider comparisons covered in the MCB engineering guide. Before ordering either line for a new board, run the selection checklist in how to select the right MCB: complete checklist to confirm fault level, curve, and accessory needs against the actual site rather than habit.

Conclusion

Acti9 iC60 and Easy9 solve different problems inside the same Schneider MCB catalog. Easy9 covers confirmed, low-fault-level residential circuits at a lower cost per way. iC60 carries the breaking-capacity range, curve spread, and accessory ecosystem — Vigi RCBO, comb busbars, auxiliary and alarm contacts, shunt trips — for boards where fault levels, load types, or monitoring requirements go beyond what a fixed residential line supports. The decision point is the board's actual fault current and functional requirements, not a default habit in either direction.
