Schneider Acti9 vs ABB F200 vs Siemens 5SV: RCCB Comparison

Which RCCB range should you specify: Schneider Acti9 iID, ABB F200, or Siemens 5SV? All three are modular DIN-rail RCCBs built to IEC 61008, available in 2P and 4P, with IΔn settings from 10 mA to 500 mA and overlapping Type A coverage per IEC 62423. The choice matters because RCBO architecture, Type F/B availability, and selectivity range differ enough between the three to change how a panel is laid out and how many spare ways a board needs. This comparison covers model ranges and current ratings, type and sensitivity coverage, RCBO form factor, selectivity above 125 A, nuisance-trip resistance, and a head-to-head spec table.

Model Ranges: Poles, Current Ratings and Series Codes

Schneider's Acti9 iID covers 2P and 4P in rated currents from 25 A to 100 A, with IΔn settings at 10, 30, 100, 300 and 500 mA. ABB's F200 range runs wider: F202 (2P) and F204 (4P) go from 25 A up to 125 A, with the same IΔn steps plus dedicated S-type selective versions built into the same catalog, and the economy FH200 line trims type coverage to hit a lower price point. Siemens covers the middle ground with 5SV3, 5SV4 and 5SV6 in 2P/4P from 16 A to 125 A, in Types AC, A and F.

The 16 A starting point on the Siemens range is the one clear gap-filler here: neither Acti9 iID nor F200 publish a rating below 25 A in this comparison, which matters on lighting or control sub-circuits sized well under a standard 25 A device. Series-code literacy also matters at order time — F202 vs F204, 5SV3 vs 5SV4 vs 5SV6 — because the wrong digit orders the wrong pole count, not just the wrong sensitivity.

Key takeaway: ABB's F200 has the widest rated-current ceiling of the three at 125 A, matching Siemens 5SV but exceeding Schneider Acti9 iID's 100 A cap — check F200 or 5SV first on a board with a single higher-current RCCB way.

Type Coverage: AC, A, F, B and SI Across the Three Brands

Type A is the common baseline in modern installations: it detects sinusoidal AC residual current plus pulsating DC, which covers most electronic loads with a switch-mode power supply. Schneider's Acti9 iID range extends to Type SI (super-immunized) and Type B within the same modular family. ABB's F200 range goes further at the modular level: Types AC, A, F and B are all available as F202/F204 variants, including a true F200 B for smooth DC residual current. Siemens' 5SV modular range covers AC, A and F; full Type B protection sits in a separate product, the 5SM3, rather than in the compact 5SV form factor.

Type B RCD is a device that trips on smooth (pure) DC residual current in addition to AC and pulsating DC, required for three-phase VFDs, EV chargers and transformerless PV inverters (per IEC 62423).

That distinction is the one to check before quoting a job with three-phase drives or DC fast chargers. If the spec calls for a single modular DIN-rail device with Type B built in, ABB's F200 B and Schneider's Acti9 iID Type B answer directly; a Siemens-based board needs the 5SM3 as a separate line item, which changes the panel layout and enclosure width, not just the price line. See Type A vs Type B RCD for VFD, EV and solar for the underlying reason Type B is mandatory there, and RCD types AC, A, F, B and SI explained for the full waveform breakdown.

Key takeaway: ABB F200 and Schneider Acti9 iID both offer Type B as a standard modular RCCB; Siemens reaches Type B only through the separate 5SM3 device, not the 5SV range.

RCBO Architecture: Add-On Block vs One-Piece Module

An RCBO combines the RCCB's earth-leakage sensing with an MCB's overload and short-circuit trip in one device. Schneider builds this differently from the other two: the Vigi iC60 is a separate earth-leakage block that clips onto an existing iC60 MCB, and the compact iDPN Vigi / Reload line is the single-module equivalent. ABB and Siemens both ship one-piece modules as the default — ABB's DS201 (1P+N) and DS202C / DS203NC, and Siemens' 5SU1 (compact 1P+N) and 5SV1.

The add-on approach has one practical advantage a one-piece module doesn't: if the MCB trips on overload, the field electrician can swap just the MCB without disturbing the earth-leakage block wiring, and stock-holding only needs one Vigi SKU across several MCB curve/rating combinations instead of a full matrix of RCBO part numbers. The trade-off is width — a Vigi block plus MCB usually occupies more DIN-rail space than a genuinely compact one-piece RCBO. For the underlying trade-off between RCD, RCCB and RCBO terminology, see MCB vs RCBO vs RCD vs RCCB differences. Browse the current residual current devices range for in-stock SKUs across all three brands, or the RCBOs collection for the one-piece and Vigi-block equivalents.

Key takeaway: Schneider's Vigi block reduces RCBO SKU count and simplifies MCB replacement in the field; ABB and Siemens one-piece RCBOs save DIN-rail width on tight boards.

Selectivity and the Point Where a Modular RCCB Stops Being the Right Tool

All three ranges offer S-type (selective, time-delayed) versions for two-stage discrimination: an upstream RCCB that should not trip for a fault already cleared by a downstream device. ABB documents this explicitly in the F200 S-type line; Schneider and Siemens apply the same selectivity principle across their instantaneous vs S/G time-delay classes.

Formula: RCD selectivity (discrimination) — Source: IEC 60947-2 Annex M / manufacturer selectivity tables

IΔn(upstream) ≥ 2 × IΔn(downstream), with an added time delay (S or G class) on the upstream device

Symbol Description Unit
IΔn(upstream) Rated residual operating current of the upstream (selective) RCD mA
IΔn(downstream) Rated residual operating current of the downstream (instantaneous) RCD mA

Above roughly 125 A, the ceiling on all three modular RCCB ranges compared here, none of the three vendors sells a fixed-current modular RCCB. The correct device at that point is a residual current relay with a separate toroid sized to the feeder: Siemens 5SM2, ABB RD3, or Schneider Vigirex. What we see in the field: teams sometimes try to stack two 125 A RCCBs in parallel to cover a bigger feeder, which does not give a valid trip characteristic — the relay-plus-toroid approach is the only correct path once a feeder is past the modular range's current ceiling.

Key takeaway: once a feeder exceeds the roughly 125 A ceiling common to Acti9 iID, F200 and 5SV, move to a residual current relay with an external toroid — not a parallel pair of modular RCCBs.

Nuisance-Trip Resistance: SI vs SIGRES

Schneider labels its enhanced-immunity range "si" (super-immunized) within Acti9 iID, built to resist transient leakage from surges and high-frequency noise without desensitizing the device to a genuine fault. Siemens addresses a different failure mode with 5SV "SIGRES": corrosion and dust resistance for humid or chemically aggressive environments, rather than surge immunity specifically. ABB's F200 range does not carry a distinct branded "super-immunized" SKU in this comparison; its type coverage (AC/A/F/B) and S-type selectivity are the levers ABB offers instead.

Super-immunized (SI) RCD is a device with additional filtering against transient or high-frequency leakage current, reducing nuisance tripping on sites with variable-speed drives, UPS units or long cable runs, without changing the rated IΔn.

This depends on which failure mode is actually causing the trips, and it's worth separating the two before reaching for the higher-spec part number: a board on a coastal or wash-down site with corrosion ingress needs SIGRES-class sealing, not surge filtering, while a board full of VFDs and switch-mode supplies needs SI filtering, not corrosion resistance. See why an RCD keeps tripping: causes and fixes for the fuller troubleshooting list.

Head-to-Head: Schneider Acti9 vs ABB F200 vs Siemens 5SV

The table below lines up the three ranges on the criteria that actually drive a spec decision: current rating, type coverage, RCBO architecture, and the standard each is built to.

Criteria Schneider Acti9 iID ABB F200 Siemens 5SV
Poles 2P / 4P 2P (F202) / 4P (F204) 2P / 4P (5SV3/5SV4/5SV6)
Current rating 25-100 A 25-125 A 16-125 A
IΔn options 10/30/100/300/500 mA 10/30/100/300/500 mA 10/30/100/300/500 mA (range-dependent)
Type coverage (modular) AC/A/SI/B AC/A/F/B AC/A/F
Type B route Built into Acti9 iID Built into F200 (F200 B) Separate 5SM3 device
RCBO form factor Add-on Vigi block on iC60, or compact iDPN One-piece DS201 / DS202C / DS203NC One-piece 5SU1 / 5SV1
Selective (S-type) Yes Yes, explicit F200 S-type Yes (S/G time-delay classes)
Nuisance-trip variant "si" super-immunized Not a distinct branded SKU here SIGRES (corrosion/humidity)
Above ~125 A Vigirex relay + toroid RD3 relay + toroid 5SM2 relay + toroid
Base standard IEC 61008 / 61009 IEC 61008 / 61009 IEC 61008 / 61009 / 62423

None of the three is a strict superset of the others. ABB F200 has the broadest modular type coverage (AC/A/F/B in one compact range) and the highest current ceiling alongside Siemens. Schneider's Acti9 iID gives the simplest RCBO stock strategy through the Vigi block. Siemens 5SV covers the widest current span at the low end (16 A) and adds SIGRES for hostile environments, at the cost of routing Type B through a separate device. For a structured way to work through sensitivity, type and pole count before comparing brands, see how to select RCD sensitivity, type and poles, and for the base terminology behind RCCB vs RCBO see the RCD protection guide.

Key takeaway: pick ABB F200 for the broadest modular type coverage, Schneider Acti9 iID for RCBO stock simplicity via the Vigi block, and Siemens 5SV for the lowest current-rating entry point plus SIGRES corrosion resistance.

Frequently Asked Questions

Which RCCB range has the widest current rating?

ABB F200 and Siemens 5SV both reach 125 A; Schneider Acti9 iID tops out at 100 A. Siemens 5SV also starts lower, at 16 A, versus 25 A for the other two.

Does Siemens 5SV offer Type B protection?

Not within the compact 5SV modular range itself. Siemens routes Type B protection — smooth DC residual current, needed for VFDs, EV chargers and transformerless PV inverters — through the separate 5SM3 device.

What is the difference between Schneider's Vigi block and a one-piece RCBO?

The Vigi iC60 is an add-on earth-leakage module that clips onto an existing iC60 MCB to form an RCBO, so the MCB can be replaced independently. ABB (DS201/DS202C/DS203NC) and Siemens (5SU1/5SV1) instead ship a single integrated RCBO module.

Can any of these three RCCBs be used above 125 A?

No. None of the three modular ranges compared here goes above 125 A. Above that, use a residual current relay with an external toroid sized to the feeder — Siemens 5SM2, ABB RD3, or Schneider Vigirex.

What does "si" or "SIGRES" mean on these RCCBs?

Schneider's "si" (super-immunized) filters transient and high-frequency leakage to cut nuisance tripping without changing the rated IΔn. Siemens' SIGRES targets a different problem: corrosion and dust resistance for humid or chemically harsh sites.

Are the IΔn sensitivity options the same across all three brands?

Largely yes — all three offer the same core IΔn steps of 10, 30, 100, 300 and 500 mA across their RCCB ranges, though exact availability varies by pole count and type within each series.

Conclusion

Pick by the constraint that actually applies to the board. If Type B has to sit in the RCCB itself rather than a separate device, ABB F200 or Schneider Acti9 iID answer directly; a Siemens-based board needs the 5SM3 alongside 5SV. If minimizing RCBO SKU count and letting field techs swap MCBs independently matters more, Schneider's Vigi-block architecture is the more flexible pattern. If the site is corrosive or humid, Siemens SIGRES is the specific answer; if it's full of VFDs and switch-mode loads causing nuisance trips, Schneider "si" targets that instead. Past roughly 125 A, none of the three modular ranges applies — move to a residual current relay and external toroid regardless of brand.
