Asea Brown Boveri S272-K2 Molded Case Circuit Breaker

ABB S272-K2 is a two-pole molded-case circuit breaker (MCCB) from ABB, designed to protect low-voltage distribution circuits in electrical panels from overloads and short circuits. The S272-K2 family covers a range of ampere ratings, with the precise rated current, short-circuit breaking capacity, and trip characteristics defined per variant in ABB catalogs; the exact specifications depend on the specific S272-K2 part you select. This MCCB is intended for use in panelboards, control cabinets, and machine protection schemes where reliable, fast isolation of faulted circuits is required. Being a molded-case breaker, it provides manual reset after tripping and is compatible with standard low-voltage distribution setups, subject to the panel's frame and busbar compatibility. The S272-K2 designation indicates a K-series trip curve variant within the S272 line, and ABB's history in this product line traces back to the ASEA Brown Boveri era, ensuring continuity of protection technology across legacy and modern installations. Typical applications include safeguarding feeders to equipment, motor circuits, and power distribution in industrial, commercial, or process environments. For designers and buyers, verify the exact voltage rating, rated current, and interruption capacity for the specific S272-K2 part in use, as well as any required accessories or mounting considerations, to ensure full compatibility with your installation.
