£195.24
The ABB S203MT-C2NA is a specialist miniature circuit breaker (MCB) from the ABB System pro M Compact S200MT series, designed for traction, railway and demanding industrial electrical applications. Featuring a C characteristic trip curve, it provides reliable overload and short circuit protection for circuits with moderate inrush currents.
The S200MT range is engineered for transport environments where safety, reliability and compact installation are essential. This MCB combines delayed thermal overload protection with electromechanical short circuit protection, helping safeguard electrical equipment while maintaining dependable operation in rolling stock and rail-related control systems.
With a rated current of 2 A, a 3P+N configuration and a 10 kA breaking capacity, the S203MT-C2NA is ideal for low-current three-phase circuits requiring neutral switching in traction, railway and specialist industrial installations.
Miniature circuit breakers such as the ABB S203MT-C2NA automatically disconnect electrical circuits when overloads or short circuits occur. The thermal mechanism responds to sustained overload conditions, while the electromechanical trip reacts quickly to fault currents.
The S200MT series is designed for traction and railway applications, making it suitable for rolling stock, transport infrastructure and specialist electrical systems where dependable circuit protection and compact DIN rail installation are required.
