Why Choose the ABB F204B+400.3 Residual Current Circuit Breaker?
The ABB F204B+400.3 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 electronic equipment. As part of the established ABB F200 RCCB series, the F204B+40/0.3 combines a 40 A rated current with comprehensive residual-current detection for demanding commercial and industrial applications.
Rated at 40 A with a 300 mA residual operating current, the F204B+40/0.3 provides Type B+ protection for installations where AC, pulsating DC, smooth DC and higher-frequency residual-current components may occur. This makes it particularly suitable for circuits containing frequency converters, inverters and other modern power electronic equipment.
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 where enhanced Type B+ protection is required.

Enhanced 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 protection covers sinusoidal AC, pulsating DC and smooth DC residual currents, while the Type B+ characteristic extends protection to higher-frequency residual-current components that can occur in modern power-electronic applications.
The ABB F204B+40/0.3 combines a 40 A current rating with a 300 mA residual-current threshold. Its Type B+ characteristic makes it particularly suitable for circuits containing frequency converters, inverters and other electronic power-conversion equipment where complex residual-current waveforms may occur.
