ABB SU201M-K2 Soft Starter For 3-Phase Motors

ABB SU201M-K2 is a 1-pole miniature circuit breaker (MCB) with a nominal current rating of 2 A and a type K tripping characteristic, engineered to interrupt overcurrent events in single-phase circuits and to protect wiring and connected equipment from damage caused by overloads. Listed to UL489 and designed for low-voltage distribution applications, the SU201M-K2 delivers a short-circuit breaking capacity of up to 10 kA (Icn 10 kA), enabling reliable fault isolation in panels and distribution boards while maintaining predictable trip behavior in multi-device protective schemes. As a member of ABB's SU201M family, the K2 variant is recognized by its 2 A rating within a compact, single-pole package, aligning with ABB's modular protection lineup and providing a straightforward, standards-based overcurrent protection option in commercial and light industrial installations. Typical applications for the SU201M-K2 include protecting small branch circuits, lighting runs, and control circuits inside electrical panels and distribution boards, where a reliable, trip-curve-specific protective device with a 10 kA fault-current rating helps ensure system safety and continuity.
