The ABB F204 AC-100/0.03 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. With a rated current of 100 A and a rated residual operating current of 30 mA, it detects sinusoidal alternating residual currents and disconnects the circuit when the specified residual-current threshold is reached. The device is suitable for compatible AC electrical distribution systems, supports DIN-rail mounting, and complies with IEC 61008 standards.
