DESCRIBE

The ABB MS116-0.63 is a single-pole (1P), miniature circuit breaker (MCB) from ABB's MS116 series. This specific model has a very low rated current of 0.63 Amperes (630 mA). It is designed for the protection of sensitive control circuits, instrumentation loops, signal circuits, or small auxiliary devices where very low operating currents are present. Its primary function is to provide reliable protection against overloads and short-circuits in these delicate applications, preventing damage to expensive equipment like PLC modules, transmitters, relays, or low-power power supplies.
