ABB SU202M-C5 Safety Relay Module Two Channel

ABB SU202M-C5 is a two-pole miniature circuit breaker (MCB) designed to provide branch-circuit protection in AC electrical installations. This C-curve device offers a 10 kA short-circuit breaking capacity and a rated current of 5 A (In = 5 A) in a 2P configuration, making it suitable for protecting two conductors or circuits within a single module. It is UL489-listed and intended for use in panels and DIN-rail enclosures, enabling reliable overcurrent protection in low-voltage distributions. The SU202M-C5 supports protection for systems up to 480Y/277 V AC and up to 96 V DC, aligning with ABB’s low-voltage protection offerings for mixed AC/DC circuits. Typical applications include safeguarding lighting and outlet circuits in commercial facilities, as well as small machinery and control circuits where two poles require coordinated protection. This ABB part is part of the SU200M family, focusing on compact, dependable overcurrent protection with a footprint that suits modular distribution boards and standard panel layouts.
