ABB SU202M-K35 Safety Relay Module For Industrial Control Systems

ABB SU202M-K35 is a two-pole miniature circuit breaker (MCCB) in ABB's SU200M family, designed to provide branch‑circuit protection with a K-curve trip characteristic and a rated current of 35 A. It is UL489-listed and offers a 10 kA short-circuit breaking capacity, with a footprint spanning two module units. The device carries alternate cataloging as SU202M-C35 for the C-curve variant, demonstrating ABB's cross-reference within the same family. Intended for use in electrical distributions that require UL489 compliance, it supports circuits up to 480Y/277 VAC and up to 96 V DC. This combination of current rating, breaking capacity, and curve type makes the SU202M-K35 suitable for protecting branch circuits and control‑panel wiring in industrial and commercial installations, where reliable interruption of fault currents is essential. ABB's catalogs and data sheets confirm its role as a protective device within the SU200M series, offering a proven solution for standard protection that aligns with UL wiring practices.
