Why Choose the ABB F204 AC-100/0.3 L Residual Current Circuit Breaker?
The ABB F204 AC-100/0.3 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. As part of the proven ABB F200 Series, it helps protect people, equipment and electrical systems while ensuring compliance with recognised international safety standards.
With a 100 A rated current and a 300 mA rated residual operating current, this RCCB is ideal for higher-capacity three-phase distribution systems where reliable earth fault protection is essential. The Type AC operating characteristic detects alternating sinusoidal residual currents, reducing the risk of electric shock and electrical fires caused by insulation failures.
The L variant features the neutral terminal positioned on the left, making it suitable for installations requiring this wiring arrangement. Its compact DIN rail design, robust construction and compatibility with ABB accessories make it an excellent choice for modern electrical distribution systems.
