Why Choose the ABB S203MT-B32NA Miniature Circuit Breaker?
The ABB S203MT-B32NA is a specialised 3P+N miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. As part of the ABB S200 MT series, it combines three protected phase poles with neutral switching in a compact modular device for industrial and traction-related circuit protection applications.
This miniature circuit breaker combines a 32 A rated current, B tripping characteristic and 10 kA short-circuit breaking capacity. The B characteristic provides responsive magnetic protection for circuits with relatively low starting and inrush currents, making the S203MT-B32NA suitable for appropriate distribution, control and equipment loads.
The 3P+N configuration enables the three phase conductors and neutral to be switched together while providing overcurrent protection through the protected phase poles. ABB order code 2CDS273446R0325 uniquely identifies this 32 A B-characteristic S203MT-B32NA circuit breaker.
