Why Choose the ABB S201MTR-K3 Miniature Circuit Breaker?
The ABB S201MTR-K3 is a specialist single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short-circuits. Part of ABB's traction-focused circuit protection portfolio, it is intended for demanding railway, rolling-stock and traction electrical installations where dependable circuit protection is required.
Featuring a 3 A rated current, Type K tripping characteristic and 10 kA breaking capacity, the S201MTR-K3 provides robust protection for low-current auxiliary, control and equipment circuits. The Type K characteristic is suited to appropriate loads with elevated short-duration starting or inrush currents, helping accommodate normal energisation peaks while maintaining overload and short-circuit protection.
The 1P configuration provides overcurrent protection and switching for a single conductor. Its compact modular format supports efficient integration into electrical distribution boards, rolling-stock equipment and control assemblies where space-efficient circuit protection is important.
