Why Choose the ABB F202 A S-40/0.3 Residual Current Circuit Breaker?
The ABB F202 A S-40/0.3 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 2CSF202201R3400, this device forms part of the trusted ABB F200 RCCB series, widely used for professional residual current protection.
This Type A selective RCCB detects alternating residual currents and pulsating DC residual currents, making it suitable for modern circuits containing 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 40 A and a 300 mA residual operating current, the ABB F202 A S-40/0.3 is suitable for distribution boards, control panels and switchgear assemblies where selective earth leakage protection and fire protection against insulation faults are required.

Selective Earth Leakage Protection for Electrical Installations
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-40/0.3 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.
Typical Applications
- Commercial distribution boards.
- Industrial control panels and switchgear.
- Building services and infrastructure systems.
- Electrical installations requiring selective RCD protection.
- Power distribution circuits with downstream residual current devices.
- Circuits requiring 40 A Type A earth leakage protection.
