Why Choose the ABB SU204M-K5 Miniature Circuit Breaker?
The ABB SU204M-K5 is a high-performance 4-pole miniature circuit breaker (MCB) designed to provide reliable branch-circuit protection against overloads and short circuits in commercial and industrial electrical installations. As part of the ABB SU200M series, it combines compact modular construction with UL 489 compliance for dependable protection in demanding electrical distribution and automation applications.
Featuring a 5 A rated current, K tripping characteristic and 10 kA interrupting rating according to UL 489, the SU204M-K5 is particularly suited to circuits with inductive loads and elevated starting currents. Its four-pole configuration provides coordinated protection and switching across multi-conductor circuits.
The SU204M-K5 uses thermal-magnetic protection technology to provide automatic disconnection during overload and short-circuit conditions. Its compact DIN-rail-mounted format enables straightforward integration into machine control panels, industrial distribution boards and automation systems.
