£147.41
The ABB F204 AC-40/0.03 is a reliable 4-pole residual current circuit breaker (RCCB) designed to provide dependable protection against earth leakage faults in residential, commercial and industrial electrical installations. As part of the trusted ABB F200 series, it automatically disconnects the electrical supply whenever dangerous residual currents are detected, helping to protect people, equipment and electrical systems.
Designed for professional DIN rail installation, the ABB F204 AC-40/0.03 is manufactured in accordance with IEC/EN 61008 and 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 electrical circuits.
With a 40 A rated current, 30 mA residual operating current and a 4-pole configuration, this RCCB provides additional protection against electric shock whilst delivering dependable earth leakage protection for three-phase electrical installations.
Residual current circuit breakers continuously monitor the balance between live conductors and disconnect the electrical supply whenever leakage current exceeds the specified threshold. This helps minimise the risk of electric shock, insulation faults and electrical fires while protecting valuable equipment.
The ABB F200 series is widely specified by electrical contractors, panel builders and industrial engineers thanks to its proven reliability, robust construction and straightforward installation across a wide range of electrical distribution systems.
