Why Choose the ABB S202M-Z30UC Miniature Circuit Breaker?
The ABB S202M-Z30UC is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in both AC and DC electrical systems. As part of the ABB System pro M compact S200 M UC series, it combines universal-current capability with robust circuit protection for industrial, automation, DC distribution and traction applications.
Featuring a 30 A rated current, Type Z tripping characteristic and 10 kA breaking capacity, the S202M-Z30UC is particularly suited to sensitive electrical and electronic circuits requiring rapid magnetic response to overcurrent conditions. The Type Z characteristic provides sensitive protection for equipment where relatively low fault-current multiples need to initiate fast disconnection.
The two-pole configuration provides simultaneous protection across two conductors, while the S200 M UC universal-current design supports both AC and DC installations. Its compact 35 mm width and DIN-rail mounting make the breaker straightforward to integrate into industrial distribution boards, machinery and control panels.

Sensitive AC and DC Circuit Protection
Miniature circuit breakers such as the ABB S202M-Z30UC protect electrical wiring and connected equipment against excessive current caused by overloads and short circuits. Thermal and magnetic operating mechanisms automatically disconnect the protected circuit when abnormal current conditions occur, helping prevent damage to wiring and equipment.
The Type Z characteristic provides sensitive magnetic tripping and is particularly useful for electronic equipment, control circuits and other loads requiring rapid response to comparatively low overcurrent levels. Combined with the universal AC/DC capability of the S200 M UC platform, the S202M-Z30UC provides a flexible protection solution for industrial automation, DC distribution and railway or traction applications.
Typical Applications
- Industrial automation and control systems.
- Sensitive electronic equipment and circuits.
- DC power distribution systems.
- Railway and traction electrical systems.
- Industrial control and distribution panels.
- Machine building and OEM electrical equipment.
- AC and DC circuits requiring Type Z protection.
