Why Choose the ABB F204 AC-40/0.5 L Residual Current Circuit Breaker?

The ABB F204 AC-40/0.5 L is a high-quality 4 pole residual current circuit breaker (RCCB) engineered to provide dependable protection against earth leakage faults in commercial, industrial and infrastructure electrical installations. As part of the trusted ABB F200 Series, it delivers reliable protection for personnel and electrical systems while helping installations comply with recognised international safety standards.

With a 40 A rated current and a 500 mA rated residual operating current, this RCCB is ideal for three-phase distribution systems requiring dependable earth fault and fire protection. The Type AC operating characteristic detects alternating sinusoidal residual currents, helping reduce 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 where this wiring arrangement is required. Its compact DIN rail design, robust construction and compatibility with ABB accessories make it an excellent choice for professional electrical installations.
