Why Choose the ABB F202 A S-100/0.5 Residual Current Circuit Breaker?
The ABB F202 A S-100/0.5 is a selective 2-pole residual current circuit breaker (RCCB) designed to provide dependable protection against earth leakage faults in residential, commercial and industrial electrical installations. Identified by ABB product code 2CSF202201R4900, this device forms part of the trusted ABB F200 RCCB series, delivering reliable protection for people, equipment and electrical systems whilst ensuring excellent selectivity with downstream protective devices.
This Type A selective RCCB detects alternating residual currents and pulsating DC residual currents, making it suitable for installations supplying modern electronic equipment. Its selective operating characteristic introduces a controlled time delay, improving discrimination with downstream RCCBs and helping minimise unnecessary power interruptions.
With a rated current of 100 A and a 500 mA residual operating current, the ABB F202 A S-100/0.5 is ideal for higher-load distribution circuits requiring selective earth leakage protection and enhanced fire protection. Its compact DIN rail mounted design enables straightforward installation within switchboards and modular electrical assemblies.

Selective Earth Leakage Protection for Electrical Installations
Residual current circuit breakers continuously monitor the balance between live and neutral conductors. If earth leakage exceeds the specified threshold, the RCCB disconnects the circuit, helping reduce the risk of electric shock and electrical fires caused by insulation faults.
The selective operating characteristic of the ABB F202 A S-100/0.5 introduces a controlled delay before tripping, allowing downstream RCCBs to clear local faults first. This improves system discrimination, increases installation reliability and reduces unnecessary interruption of healthy circuits.
Typical Applications
- Main distribution boards.
- Industrial switchgear.
- Commercial electrical installations.
- Building services infrastructure.
- Control panels.
- Installations requiring selective residual current protection.
