Overview

The ABB SU201MR-K4 is a 1-pole Miniature Circuit Breaker (MCB) from the SYSTEM PRO M COMPACT™ series, engineered for branch circuit protection in North American applications. Rated at 4A with a K-type trip curve, it is optimized for circuits with high inrush currents, such as motor loads, transformers, and inductive equipment, preventing nuisance tripping while ensuring reliable short-circuit interruption. The SU201MR-K4 offers a 10kA breaking capacity, certified to UL 489 and CSA 22.2 No. 5 standards for use up to 480Y/277V AC and 48/96V DC. It features ring cable lug terminals for simplified wiring and installation on 35mm DIN rails. This model is compatible with auxiliary contacts, bell alarms, cuttable busbars, LOTO adapters, and rotary handle mechanisms, providing flexibility for enhanced functionality and safety. Manufactured in the US, the SU201MR-K4 measures 69mm (W) x 115mm (H) x 49.2mm (D) with terminal dimensions of 25mm (H) x 25mm (W) x 6.8mm (D). Designed for front panel or dead-front mounting, it is ideal for industrial, commercial, and infrastructure applications requiring precise overcurrent protection.
