Why Choose the ABB SU203M-C5 Miniature Circuit Breaker?
The ABB SU203M-C5 is a compact and reliable three-pole miniature circuit breaker (MCB) designed for branch-circuit overcurrent and short-circuit protection in industrial, commercial and automation applications. As part of the proven ABB SU200M series, it is specifically developed for applications requiring UL 489 branch-circuit protection while supporting North American and international electrical standards.
This miniature circuit breaker combines a 5 A rated current, C tripping characteristic and 10 kA interrupting rating according to UL 489. Its three-pole configuration enables simultaneous protection of three conductors, making it particularly suitable for three-phase circuits in machinery, control panels and industrial electrical distribution systems.
With ratings of 480Y/277 V AC and 96 V DC, the SU203M-C5 provides flexible protection for AC and DC applications. It also offers a rated ultimate short-circuit breaking capacity of 15 kA at 400 V AC according to IEC/EN 60947-2, making it a versatile choice for machine builders and panel designers serving North American and global markets.
