ABB F202 A-40/0.3 residual current circuit breaker, a 2-pole Type A RCCB with 40 A rated current and 300 mA residual operating current for earth leakage protection in electrical installations.
£197.32
The ABB F202 A-40/0.3 is a dependable 2-pole residual current circuit breaker (RCCB) designed to protect electrical installations against earth leakage faults. Identified by ABB product code 2CSF202101R3400, this device is part of the trusted ABB F200 RCCB series, widely used in residential, commercial and industrial distribution systems.
This Type A RCCB detects alternating residual currents and pulsating DC residual currents, making it suitable for circuits supplying modern electronic loads. Its compact modular construction, screw terminal connection and DIN rail mounting allow straightforward installation within consumer units, distribution boards, control panels and switchgear assemblies.
With a rated current of 40 A and a 300 mA residual operating current, the ABB F202 A-40/0.3 is suitable for electrical circuits requiring reliable earth fault protection and fire protection against insulation faults. Its robust ABB design supports safe, compliant and long-lasting electrical installations.
Residual current circuit breakers monitor the balance of current flowing through live and neutral conductors. If an imbalance occurs due to leakage current to earth, the RCCB disconnects the circuit quickly, helping reduce the risk of electric shock, insulation damage and electrical fire.
The ABB F200 series is engineered for dependable residual current protection across a wide range of installations. The F202 A-40/0.3 provides robust protection for 40 A circuits while maintaining a compact two-module DIN rail footprint, making it a practical choice for professional electrical distribution applications.
