ABB F204 A-63/0.5-L residual current circuit breaker, a four-pole Type A RCCB rated at 63 A with 500 mA residual current sensitivity and left-side neutral terminal for three-phase electrical installations.
£276.20
The ABB F204 A-63/0.5-L is a high-quality four-pole residual current circuit breaker (RCCB) designed to provide reliable earth fault protection in commercial and industrial electrical installations. As part of the trusted ABB F200 RCCB series, it helps protect people and installations by detecting residual current faults and disconnecting the circuit when leakage current exceeds the rated threshold.
This Type A RCCB is suitable for installations where protection against alternating residual currents and pulsating DC residual currents is required. Its 63 A rated current and 500 mA residual current sensitivity make it well suited for distribution boards, control panels and electrical systems requiring dependable upstream or installation-level residual current protection.
With its four-pole configuration and neutral terminal on the left, the F204 A-63/0.5-L is designed for three-phase electrical systems where left-side neutral layout is required. DIN rail mounting, compact modular dimensions and ABB build quality make it a practical choice for professional electrical contractors, panel builders and maintenance engineers.
Residual current circuit breakers monitor the difference between live and neutral conductors. If a leakage current to earth is detected, the RCCB disconnects the circuit to help reduce the risk of electric shock, fire and damage to electrical equipment.
The ABB F204 A-63/0.5-L is designed for professional electrical distribution applications where stable and dependable residual current protection is required. Its Type A detection capability makes it suitable for modern installations containing equipment that may generate pulsating DC residual currents.
