Why Choose the ABB SU202M-C0.5 Miniature Circuit Breaker?
The ABB SU202M-C0.5 is a compact 2-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for low-current branch circuits. As part of the ABB SU200M / System pro M compact series, it combines UL 489 branch-circuit protection with a modular design suited to industrial, commercial and OEM electrical installations.
Featuring a C tripping characteristic, the SU202M-C0.5 is suited to circuits with moderate inrush currents while maintaining dependable protection against abnormal overcurrent conditions. Its low 0.5 A current rating makes it particularly useful for control, instrumentation, automation and auxiliary circuits requiring dedicated low-current protection.
With two poles and a 10 kA UL 489 interrupting rating, the SU202M-C0.5 provides robust branch-circuit protection in a compact DIN rail format. The combination of ABB's SU200M platform, C characteristic and low current rating makes this breaker a practical choice for protecting sensitive control circuits and low-power equipment within industrial electrical panels.
