The ABB MS2X-10.0 is a 10 kA rated miniature circuit breaker (MCB) from the MSxxx series within the broader System M (M200 S-series) product family.
This device is a highly compact, single-pole MCB with a rated current of 10.0 Amperes. Its primary function is to provide reliable overload and short-circuit protection for electrical circuits in residential, commercial, and light industrial applications. It operates by automatically disconnecting the circuit when a fault is detected, thereby protecting the wiring and connected equipment from damage and preventing fire hazards.
