ABB SU201M-K6 Industrial Safety Relay Module Series

ABB SU201M-K6 is a 1‑pole miniature circuit breaker (MCB) from ABB’s SU200M family, designed for branch‑circuit protection in low‑voltage AC installations. It is rated for 6 A and uses a K‑curve trip characteristic, providing a defined instantaneous trip for moderate overloads and inrush currents. The device is rated for up to 480Y/277 V AC and offers a short‑circuit breaking capacity of 10 kA (Icn), making it suitable for typical commercial electrical distributions that may experience brief fault currents. The SU201M‑K6 is intended for single‑pole protection in ABB System Pro M Compact panel configurations and is compatible with standard DIN‑rail mounting. This model is listed under UL 489, aligning with North American electrical standards, and is used to protect individual circuits such as lighting, receptacles, or control wiring within ABB‑based panels, providing predictable coordination with downstream protective devices in compact installations.
