Why Choose the ABB S202MT-K3UC Miniature Circuit Breaker?
The ABB S202MT-K3UC 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 K-characteristic tripping and a high 10 kA short-circuit breaking capacity.
Developed specifically with transportation and industrial applications in mind, the S200 MT UC range provides dependable universal-current protection in a compact modular format. The S202MT-K3UC protects both poles and mounts directly onto DIN rail, making it suitable for railway, traction, rolling-stock, automation and industrial electrical installations.
With a rated current of 3 A, K tripping characteristic and 10 kA short-circuit breaking capacity, the S202MT-K3UC is particularly suitable for circuits containing loads with comparatively high starting or inrush currents. Its 440 V rated voltage and AC/DC capability provide flexible protection for alternating-current and direct-current systems.
