ABB SU201M-K7 Industrial Safety Relay Module

ABB SU201M-K7 is a 1-pole miniature circuit breaker rated for 7 A, designed for 277 VAC circuits. It provides overcurrent protection for a single live conductor in low-voltage distribution panels and is part of ABB's SU/M family of compact breakers. Catalog data show multiple short-circuit current ratings at 277 VAC for the SU201M-K7 family, including 4,095 A, 7,500 A, and 10,000 A, enabling selection to match the system's protection requirements. This makes the SU201M-K7 suitable for protecting lighting and general-power circuits in commercial and light-industrial applications. For the exact Icu rating and mechanical dimensions, refer to ABB literature or distributor data to ensure compatibility with your enclosure and protection goals.
