Why Choose the ABB S202MT-Z3UC Miniature Circuit Breaker?
The ABB S202MT-Z3UC is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect cables and circuits against overload and short-circuit conditions in demanding AC and DC applications. As part of the ABB S200 MT UC universal current series, it combines a 3 A rated current with sensitive Z-characteristic tripping and a high 10 kA short-circuit breaking capacity.
Developed for transportation and industrial applications, the S200 MT UC range provides dependable universal-current protection in a compact modular format. The S202MT-Z3UC protects both poles and mounts directly onto DIN rail, making it suitable for railway, traction, rolling-stock, automation and industrial electrical installations where sensitive circuit protection is required.
With a rated current of 3 A, Z tripping characteristic and 10 kA short-circuit breaking capacity, the S202MT-Z3UC is particularly suited to sensitive circuits where rapid magnetic disconnection at comparatively low fault-current levels is desirable. Its 440 V rated voltage and AC/DC capability provide flexible protection for alternating-current and direct-current systems.

Sensitive AC/DC Protection for Railway and Industrial Circuits
Miniature circuit breakers such as the ABB S202MT-Z3UC automatically disconnect a circuit when excessive current occurs as a result of an overload or short circuit. This helps protect cables, conductors and connected electrical equipment while allowing the breaker to be reset after the fault has been identified and corrected.
The S200 MT UC series is engineered for universal-current and transportation applications. Its Z characteristic provides sensitive magnetic protection and is suited to circuits where rapid disconnection at comparatively low fault-current levels is required, making the S202MT-Z3UC particularly useful for sensitive control, auxiliary, signalling and electronic loads.
Typical Applications
- Railway and traction electrical systems.
- Rolling-stock electrical installations.
- Sensitive industrial control circuits.
- Automation and control panels.
- Auxiliary and signalling circuits.
- Electronic equipment protection.
- AC and DC industrial electrical systems.
