Why Choose the ABB F204 AC-100/0.5 Residual Current Circuit Breaker?
The ABB F204 AC-100/0.5 (Product Code: 2CSF204001R4900) is a premium 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 proven ABB F200 series, it helps protect both people and equipment by automatically disconnecting the electrical supply when dangerous residual currents are detected.
Manufactured to meet IEC/EN 61008, the ABB F204 AC-100/0.5 combines dependable performance with a compact DIN rail mounted design, making installation straightforward within distribution boards, switchgear assemblies and industrial control panels. Its robust construction delivers long service life even in demanding environments.
With a 100 A rated current, 500 mA residual operating current and Type AC protection, this RCCB is suitable for three-phase electrical systems where reliable earth leakage protection is required against sinusoidal alternating residual currents.
