ABB F204 AC-63/0.1-L 4 pole residual current circuit breaker with 63 A rated current, 100 mA sensitivity, Type AC protection and left-side neutral configuration for electrical distribution applications.
£199.33
The ABB F204 AC-63/0.1-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 people, equipment and electrical systems.
Designed for professional DIN rail installation, the ABB F204 AC-63/0.1-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 63 A rated current, 100 mA residual operating current and a 4-pole configuration, this RCCB provides reliable earth leakage protection for three-phase electrical installations where a 100 mA sensitivity level is required.
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 reduce risks associated with insulation faults, equipment damage and electrical hazards.
The ABB F204 AC-63/0.1-L is designed for installations requiring a left-side neutral arrangement. Its compact modular construction, ABB engineering quality and DIN rail format make it a dependable choice for electrical contractors, panel builders and industrial engineers.
