Why Choose the ABB F204 AC-125/0.3 Residual Current Circuit Breaker?
The ABB F204 AC-125/0.3 is a dependable 4-pole residual current circuit breaker (RCCB) designed to protect electrical installations against earth leakage faults. As part of the trusted ABB F200 series, this device helps improve electrical safety by automatically disconnecting the circuit when residual current exceeds the rated threshold.
Built for commercial, industrial and distribution board applications, the F204 AC-125/0.3 provides robust residual current protection in a compact DIN rail format. Its Type AC operating characteristic is suitable for circuits where sinusoidal alternating residual currents may occur, making it a practical choice for many standard AC electrical systems.
With a rated current of 125 A and a rated residual current of 300 mA, the ABB F204 AC-125/0.3 is suitable for higher-current installations where reliable earth fault protection is required. The 4-pole configuration supports three-phase and neutral circuits in distribution and control panel environments.
