£192.74
The ABB F204 AC-25/0.5 is a high-quality 4-pole residual current circuit breaker (RCCB) engineered to provide reliable protection against earth leakage faults in commercial, industrial and residential electrical installations. As part of the proven ABB F200 series, it enhances electrical safety by disconnecting the circuit whenever a potentially hazardous residual current is detected.
Designed to meet the requirements of IEC/EN 61008, the ABB F204 AC-25/0.5 delivers dependable protection while maintaining a compact DIN rail mounted design for straightforward installation within distribution boards and control panels. Its robust construction ensures long service life in demanding electrical environments.
With a 25 A rated current, 500 mA residual operating current and Type AC protection, this RCCB is ideal for applications requiring protection against sinusoidal alternating residual currents while helping reduce the risk of equipment damage and fire caused by earth faults.
Residual current circuit breakers continuously monitor the balance of current flowing through live conductors and disconnect the electrical supply whenever leakage current exceeds the specified threshold. This helps protect electrical installations against insulation faults while reducing the risk of electric shock and electrical fires.
The ABB F200 series is widely used by electrical contractors, panel builders and industrial engineers thanks to its proven reliability, high build quality and straightforward installation within modern distribution systems.
