Why Choose the ABB F204 AC-40/0.3-L Residual Current Circuit Breaker?
The ABB F204 AC-40/0.3-L is a dependable 4-pole residual current circuit breaker (RCCB) designed to provide reliable protection against earth leakage faults in residential, commercial and industrial electrical installations. As part of the trusted ABB F200 series, it disconnects the electrical supply when residual current exceeds the rated threshold, helping to protect equipment, wiring and electrical systems.
Designed for professional DIN rail installation, the ABB F204 AC-40/0.3-L is suitable for use in distribution boards, switchgear assemblies and control panels. Its Type AC operating characteristic detects sinusoidal alternating residual currents commonly found in standard AC circuits, while the L version is suitable for installations where the neutral connection is positioned on the left.
With a 40 A rated current, 300 mA residual operating current and a 4-pole configuration, this RCCB provides reliable earth leakage protection for three-phase electrical installations where a 300 mA sensitivity level is required.
