Overview

The ABB SU201M-K25 (SKU: SU201M-K25) is a UL489-certified single-pole (1P) miniature circuit breaker designed for branch circuit protection in North American electrical systems. This device features a 25A current rating and a 10kA interrupting capacity at 120/240V AC, ensuring reliable protection against overcurrents and short circuits. The K-characteristic trip curve provides selective coordination, reducing nuisance tripping while delivering rapid fault response. Its thermal-magnetic trip mechanism ensures consistent operation across varying environmental conditions. The compact 1P design is optimized for space-constrained electrical panels and distribution boards. Certified to UL489 standards, the SU201M-K25 meets safety requirements for residential, commercial, and light industrial applications. It is specifically suited for protecting sensitive loads and equipment in 120/240V AC systems, including lighting circuits, small motors, and general-purpose branch circuits. The breaker’s 10kA interrupting rating ensures compliance with North American electrical codes, while its K-characteristic curve makes it ideal for applications requiring higher inrush currents, such as transformers or motors.
