ABB F202 A S-100/0.3 residual current circuit breaker, a 2-pole Type A selective RCCB with 100 A rated current and 300 mA residual operating current for earth leakage protection in electrical installations.
£292.20
The ABB F202 A S-100/0.3 is a selective 2-pole residual current circuit breaker (RCCB) designed to provide dependable earth leakage protection in residential, commercial and industrial electrical installations. Identified by ABB product code 2CSF202201R3900, this device forms part of the trusted ABB F200 RCCB series, widely used for professional residual current protection in distribution boards and switchgear.
This Type A selective RCCB detects alternating residual currents and pulsating DC residual currents, making it suitable for circuits supplying modern electrical and electronic equipment. The selective operating characteristic helps improve discrimination with downstream residual current devices, reducing unnecessary disconnection and supporting continuity of supply.
With a rated current of 100 A and a 300 mA residual operating current, the ABB F202 A S-100/0.3 is ideal for higher-load circuits where selective earth leakage protection and fire protection against insulation faults are required. Its compact DIN rail mounting format allows straightforward installation inside modular electrical enclosures.
Residual current circuit breakers monitor the balance of current flowing through live and neutral conductors. If leakage current to earth creates an imbalance above the trip threshold, the RCCB disconnects the circuit to help reduce the risk of electric shock, insulation damage and electrical fire.
The ABB F202 A S-100/0.3 provides selective residual current protection, helping coordinate with downstream protective devices. This makes it particularly useful in installations where continuity of supply and discrimination between protective levels are important.
