Why Choose the ABB S201MT-B30 Miniature Circuit Breaker?

The ABB S201MT-B30 is a high-performance single-pole miniature circuit breaker (MCB) designed to protect cables and electrical circuits against overloads and short circuits in demanding industrial, railway and traction applications. As part of the specialised ABB S200 MT series, it combines a 30 A rated current, Type B tripping characteristic and 10 kA short-circuit breaking capacity in a compact DIN-rail-mounted format.

Developed specifically for transportation and rolling-stock electrical systems, the S200 MT range provides dependable circuit protection while meeting stringent railway requirements. The series complies with IEC/EN 60898-1 and IEC/EN 60947-2 and meets railway-related fire, shock and vibration requirements, making it suitable for electrical installations exposed to demanding operating conditions.

With a rated current of 30 A, a Type B tripping characteristic and a short-circuit breaking capacity of 10 kA, the S201MT-B30 provides responsive protection for circuits with relatively low starting and inrush currents. Its compact single-pole construction enables straightforward integration into electrical distribution boards, control panels and traction equipment.

Reliable Circuit Protection for Traction and Industrial Systems

Miniature circuit breakers such as the ABB S201MT-B30 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 providing a convenient resettable alternative to conventional fuse-based protection.

The ABB S200 MT series is engineered for demanding transportation and industrial environments. The Type B characteristic provides responsive magnetic tripping for circuits with relatively low inrush currents, while the S201MT-B30's railway-oriented construction makes it particularly suitable for auxiliary, distribution and equipment circuits in rolling stock and traction installations.

Typical Applications

• Railway and rolling-stock electrical systems.
• Traction auxiliary electrical circuits.
• Low-inrush distribution circuits.
• Industrial control and distribution systems.
• Control panels and electrical cabinets.
• Auxiliary power and electrical equipment.
• Cable and conductor overload protection.
