Why Choose the ABB SH202-C20 Miniature Circuit Breaker?
The ABB SH202-C20 is a compact and reliable miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in residential and similar low-voltage electrical installations. As part of the ABB Compact Home SH200 series, it combines a 2-pole configuration, C tripping characteristic and 20 A rated current in a convenient DIN rail-mounted format.
This current-limiting circuit breaker uses complementary thermal and electromagnetic tripping mechanisms to protect electrical circuits against sustained overloads and short-circuit faults. Its modular construction allows straightforward integration into distribution boards, while the two-pole arrangement enables simultaneous switching and protection of both poles.
With a rated current of 20 A, a Type C tripping characteristic and a rated short-circuit breaking capacity of 6 kA at 400 V AC, the SH202-C20 provides dependable protection for appropriately rated low-voltage circuits. The Type C characteristic makes it suitable for general-purpose loads that can produce moderate short-duration starting currents.
