Why Choose the ABB F204 AC-63/0.5 L Residual Current Circuit Breaker?
The ABB F204 AC-63/0.5 L is a high-quality 4 pole residual current circuit breaker (RCCB) designed to provide reliable protection against earth leakage faults in commercial, industrial and infrastructure electrical installations. As part of the trusted ABB F200 Series, it helps protect people, equipment and electrical systems by disconnecting the supply when residual fault current is detected.
Featuring a 63 A rated current and a 500 mA rated residual operating current, this RCCB is suitable for three-phase distribution systems where dependable earth fault protection and fire risk reduction are required. The Type AC tripping characteristic detects alternating sinusoidal residual currents, making it suitable for standard AC electrical circuits.
The L variant features the neutral terminal positioned on the left, making it suitable for switchboards and distribution boards requiring this specific wiring arrangement. Its DIN rail mounting design, robust construction and ABB engineering quality make it a dependable choice for professional electrical installations.
