The ABB F204 B-63/0.3 is a high-quality residual current circuit breaker (RCCB) designed to provide reliable earth fault protection in commercial, industrial and specialist electrical installations. Part of the trusted ABB F200 series, it helps protect people, equipment and electrical systems by disconnecting the supply when residual fault currents are detected.
With a 63 A rated current, 300 mA residual current sensitivity and Type B tripping characteristic, the F204 B-63/0.3 is suitable for applications where smooth DC residual currents may occur. This makes it particularly valuable for installations involving variable speed drives, EV charging equipment, photovoltaic systems and modern power electronics.
The ABB F204 B-63/0.3 features a 4-pole configuration for three-phase systems with neutral, compact modular dimensions and DIN rail mounting for straightforward installation in distribution boards, control panels and switchgear assemblies.
Residual current circuit breakers such as the ABB F204 B-63/0.3 monitor the balance between live and neutral conductors. If leakage current to earth is detected, the RCCB disconnects the circuit to help reduce the risk of electric shock, equipment damage and electrical fire hazards.
The Type B sensitivity of this device makes it suitable for installations where smooth DC fault currents may be present. This is important in systems using inverters, drives, rectifiers and other electronic equipment that can produce residual current waveforms beyond standard AC or Type A detection.
