Why Choose the ABB F204 A-125/0.03 Residual Current Circuit Breaker?
The ABB F204 A-125/0.03 is a premium 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 people and electrical systems by disconnecting the supply whenever dangerous residual current is detected.
With a 125 A rated current and a highly sensitive 30 mA rated residual operating current, this RCCB is ideal for high-capacity three-phase installations requiring enhanced personnel protection. Its Type A operating characteristic detects both alternating sinusoidal residual currents and pulsating DC residual currents, making it suitable for modern electrical systems incorporating electronic equipment.
Designed for DIN rail mounting, the ABB F204 A-125/0.03 combines compact dimensions, robust construction and compatibility with ABB accessories. Its proven reliability and long service life make it an excellent solution for electrical distribution boards, switchgear assemblies and industrial control panels.
