Why Choose the ABB S202MT-K1UC Miniature Circuit Breaker?
The ABB S202MT-K1UC 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 1 A rated current with K-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-K1UC protects both poles and mounts directly onto DIN rail, making it suitable for integration into railway, traction, rolling-stock, automation and industrial electrical installations.
With a rated current of 1 A, K tripping characteristic and 10 kA short-circuit breaking capacity, the S202MT-K1UC is particularly suitable for low-current circuits containing loads with comparatively high starting or inrush currents. Its 440 V AC/DC rating provides flexible protection for both alternating-current and direct-current systems.
