Why Choose the ABB F204B400.5 Residual Current Circuit Breaker?
The ABB F204B400.5 is a high-performance four-pole Type B residual current circuit breaker (RCCB) designed to provide advanced earth-leakage protection in electrical installations containing power electronics and equipment capable of producing DC residual currents. As part of the established ABB F200 RCCB series, the F204 B-40/0.5 provides comprehensive residual-current detection for demanding commercial and industrial applications.
Rated at 40 A with a 500 mA residual operating current, the F204 B-40/0.5 detects sinusoidal AC, pulsating DC and smooth DC residual currents. Its Type B characteristic makes it suitable for circuits containing frequency converters, inverters, variable-speed drives and other power electronic equipment where complex residual-current waveforms may occur.
The four-pole configuration supports three-phase electrical distribution systems requiring comprehensive residual-current protection. Its modular DIN-rail construction enables straightforward integration into compatible distribution boards, switchboards and control panels.

Advanced Type B Residual-Current Protection
Residual current circuit breakers monitor the current balance between the conductors of a protected circuit and disconnect the supply when leakage to earth reaches the specified operating threshold. Type B RCCBs extend protection beyond Type AC and Type A devices by detecting smooth DC residual currents in addition to sinusoidal AC and pulsating DC fault currents.
This capability makes the ABB F204 B-40/0.5 particularly suitable for electrical installations incorporating frequency converters, inverters and other power electronic equipment. Its combination of a 40 A current rating and 500 mA residual-current threshold provides dependable earth-leakage protection where complex residual-current waveforms may occur.
Typical Applications
- Variable-speed drive and frequency-converter circuits.

- Industrial power electronic systems.
- Commercial and industrial electrical distribution systems.
- Three-phase control and distribution panels.
- Electrical systems where smooth DC residual currents may occur.
- Applications requiring 500 mA Type B residual-current protection.
