Why Choose the ABB F204 A-25/0.3 Residual Current Circuit Breaker?
The ABB F204 A-25/0.3 is a high-quality 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 trusted ABB F200 Series, it helps protect people, equipment and electrical systems by disconnecting the supply when residual fault current is detected.
Featuring a 25 A rated current and a 300 mA rated residual operating current, this RCCB is suitable for three-phase distribution systems where reliable earth fault protection and fire risk reduction are required. Its Type A tripping characteristic detects both alternating sinusoidal residual currents and pulsating DC residual currents, making it suitable for many modern electrical installations containing electronic equipment.
Designed for DIN rail mounting, the ABB F204 A-25/0.3 combines compact dimensions, robust construction and excellent compatibility with ABB accessories. Its professional-grade build quality makes it a dependable choice for distribution boards, switchgear assemblies and industrial control panels.
