ABB SU201M-Z10A DIN Rail Mount Circuit Breaker

ABB SU201M-Z10A is a one-pole miniature circuit breaker from ABB’s System pro M compact family, delivering 10 A with a 10 kA short-circuit interrupt rating and a Z-curve thermal-magnetic trip characteristic for precise overcurrent protection. It protects branch circuits in AC systems up to 277 VAC and 480Y VAC, and DC circuits up to 96 V, with a 50/60 Hz rating. The device is designed for DIN-rail mounting on standard TH35 rails and uses screw-terminal connections for secure wiring. Its compact footprint is approximately 69 mm long, 17.5 mm wide, and 111 mm high, with IP20 enclosure protection and an operating temperature range of -25 to 55 C. UL489-listed, this MCB is commonly used to protect small loads and control circuits in control panels, machinery, and building automation within commercial and light-industrial environments.
