Why Choose the ABB S202MT-B35 Miniature Circuit Breaker?
The ABB S202MT-B35 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding railway, traction and industrial electrical systems. Part of the specialised ABB S 200 MT series, it combines a 35 A rated current, Type B tripping characteristic and 10 kA breaking capacity in a compact modular design.
Developed specifically for demanding traction applications, the S 200 MT range provides circuit protection for rolling-stock installations where robust electrical performance and resistance to challenging operating conditions are important. Its modular construction also supports efficient integration into distribution boards, auxiliary systems and industrial control panels.
With a rated current of 35 A and a 2-pole configuration, the S202MT-B35 is well suited to auxiliary, distribution and equipment circuits with relatively low normal inrush currents. Its Type B characteristic provides sensitive magnetic short-circuit protection, making it particularly suitable for resistive loads and circuits where rapid fault disconnection is required.
