Why Choose the ABB F204 AC-25/0.5 L Residual Current Circuit Breaker?
The ABB F204 AC-25/0.5 L is a premium 4 pole residual current circuit breaker (RCCB) designed to provide dependable protection against earth leakage faults in commercial, industrial and infrastructure electrical installations. Part of the proven ABB F200 Series, it delivers reliable protection for people and electrical systems while meeting recognised international safety standards.
Featuring a 25 A rated current and a 500 mA rated residual operating current, this RCCB is designed for three-phase electrical distribution systems where dependable earth fault protection and enhanced fire protection are required. The Type AC operating characteristic detects alternating sinusoidal residual currents, helping reduce the risk of electric shock and insulation-related electrical fires.
The L variant incorporates a left-hand neutral terminal configuration, making it suitable for switchboards requiring this wiring arrangement. Its compact DIN rail design, high-quality construction and compatibility with ABB accessories make it an excellent choice for professional electrical installations.
