2CSF502110R2400 ABB F402A-40/0.1 RCCB 40 A 2P Type A 100 mA

Why Choose the ABB F402A-40/0.1 Residual Current Circuit Breaker?

The ABB F402A-40/0.1 is a reliable 40 A Type A residual current circuit breaker (RCCB) designed to protect electrical installations against earth leakage and residual fault currents. As part of the ABB F400 series for the SMISSLINE plug-in system, this 2-pole device provides dependable residual-current protection with convenient integration into modular electrical distribution assemblies.

The Type A residual-current characteristic detects both sinusoidal alternating residual currents and pulsating DC residual currents, making the F402A-40/0.1 suitable for modern circuits containing electronic equipment and other loads capable of producing pulsating residual currents. It provides protection against indirect contact and helps protect installations against the effects of earth faults.

With a rated current of 40 A, a rated residual operating current of 100 mA and a 2-pole configuration, the F402A-40/0.1 is suitable for residential, commercial and industrial electrical distribution. It complies with IEC/EN 61008 and is identified by ABB order code 2CSF502110R2400.

Reliable Residual-Current Protection for Electrical Installations

Residual current circuit breakers continuously monitor the balance of current flowing through the conductors of a protected circuit. If current leaks to earth and the residual current reaches the operating threshold, the RCCB disconnects the circuit to help protect the electrical installation and reduce hazards associated with earth faults.

The ABB F402A-40/0.1 uses a Type A characteristic, enabling detection of both sinusoidal AC and pulsating DC residual currents. Its 100 mA operating threshold makes it suitable for earth-fault protection applications where this residual-current sensitivity is specified, while its compact SMISSLINE-compatible construction supports efficient modular distribution.

Typical Applications
