Why Choose the ABB SU203M-K13 Miniature Circuit Breaker?
The ABB SU203M-K13 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in industrial and commercial electrical systems. As part of the ABB SU200M miniature circuit breaker series, it is designed for applications requiring UL 489 branch-circuit protection in a compact DIN-rail-mounted format.
This breaker combines a 13 A rated current with a K tripping characteristic, making it particularly suitable for circuits supplying inductive loads and equipment that can produce elevated starting or inrush currents. Its three-pole configuration enables coordinated protection across three conductors for machinery, control equipment and other three-phase applications.
With a 10 kA short-circuit interrupting rating and UL 489 classification, the SU203M-K13 provides robust branch-circuit protection for demanding electrical installations. Its modular construction enables straightforward integration into DIN-rail-mounted control panels and equipment assemblies.
