The ABB 2CDS251001R0634 is a single‑pole, type C miniature circuit breaker from ABB’s System pro M compact S200 series. This compact overcurrent protection device is designed for the protection of electrical circuits against overloads and short‑circuits in residential, commercial, and light industrial installations. It features a thermal‑magnetic tripping mechanism that reacts to sustained overloads and instantaneous short‑circuit currents, offering reliable performance and safety in low‑voltage AC and DC applications. The breaker can also accommodate auxiliary accessories such as signalling contacts for enhanced monitoring.
