The ABB F204 AC-100/0.3 IEC Residual Current Circuit Breaker (RCCB) is a four-pole electrical protection device from ABB's F200 series. It is designed to protect people and electrical installations against earth-leakage currents. The device has a rated current of 100 A and a rated residual operating current of 300 mA. It detects sinusoidal alternating residual currents and disconnects the circuit when the specified residual-current threshold is reached. Suitable for compatible AC electrical distribution systems, it supports DIN-rail mounting and complies with IEC 61008 standards.
