Why Choose the ABB F404B-40/0.3 RCCB?
The ABB F404B-40/0.3 is a 40 A, 4-pole Type B residual current circuit breaker (RCCB) designed for direct integration with the ABB SMISSLINE TP plug-in system. With a rated residual operating current of 300 mA, it provides residual-current protection for demanding commercial and industrial low-voltage installations.
Type B residual-current detection makes the F404B-40/0.3 suitable for circuits where sinusoidal AC, pulsating DC and smooth DC residual currents may occur, including installations containing power-electronic equipment. The device is also short-time delayed and offers a surge-current withstand capability of 3 kA, helping improve operational reliability in demanding electrical systems.
Rated at 40 A and 400 V AC, the F404B-40/0.3 combines four-pole switching with a 300 mA residual-current rating. Its plug-in design allows direct connection to the SMISSLINE TP socket-base system, while ABB order code 2CCG000056R0001 identifies this specific Type B configuration.

Type B Residual-Current Protection for SMISSLINE TP Systems
Modern commercial and industrial installations increasingly contain electronic equipment capable of generating residual currents with waveforms that extend beyond conventional sinusoidal AC. Type B RCCBs are designed to detect a broad range of residual-current forms, including smooth DC and residual currents associated with power-electronic equipment such as frequency converters.
The ABB F404B-40/0.3 combines this Type B detection capability with a 40 A current rating, 300 mA residual-current sensitivity and direct SMISSLINE TP plug-in connection. This makes it particularly suitable for modular distribution systems where dependable residual-current protection and efficient installation are required.
Typical Applications
- ABB SMISSLINE TP plug-in distribution systems.
- Commercial and industrial low-voltage distribution boards.
- Circuits containing frequency converters and power-electronic equipment.
- Three-phase installations where smooth DC residual currents may occur.
- Industrial machinery and automation systems.
- Electrical installations requiring 300 mA Type B residual-current protection.
