Why Choose the ABB S203MT-D32 Miniature Circuit Breaker?
The ABB S203MT-D32 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical systems. Part of ABB's traction-focused circuit protection range, it is suited to industrial, transportation and railway applications requiring dependable protection of electrical circuits.
The S203MT-D32 combines thermal-magnetic protection with a Type D tripping characteristic. Type D protection is particularly suitable for circuits supplying equipment with high starting or inrush currents, helping reduce unwanted magnetic tripping during normal start-up while maintaining effective overload and short-circuit protection.
With a rated current of 32 A, three protected poles and a rated short-circuit breaking capacity of 10 kA, the S203MT-D32 provides robust protection for demanding electrical circuits. Its modular construction supports convenient integration into industrial control panels, auxiliary systems and railway or traction equipment.
