FAQ

What is the difference between an RCCB like the F 372 and an MCB?

An RCCB (Residual Current Circuit Breaker) is designed to protect against electric shock from earth faults by detecting small leakage currents. An MCB (Miniature Circuit Breaker) protects equipment against overcurrents (overload and short-circuits). They serve different but complementary safety functions.

Is this RCCB suitable for protecting circuits with modern electronic devices?

The F 372 is a Type AC RCCB, which is designed to detect sinusoidal AC fault currents. For circuits with modern electronics that can produce pulsating DC fault currents, a Type A or Type B RCCB is generally recommended for enhanced safety.

How do I correctly test the functionality of this F 372 RCCB?

The functionality should be checked regularly, typically every month, by pressing the ‘T’ or ‘TEST’ button on the front of the device. When pressed, the RCCB should trip immediately, cutting off the power. If it does not trip, it must be replaced by a qualified electrician.
