Description

Compact and reliable MCB for diverse applications.
The ABB S203-B50 Miniature Circuit Breaker is a high-performance electrical safety device designed to protect electrical circuits from overloads and short circuits. It features a current-limiting design with two distinct tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanic mechanism for short circuit protection. This breaker is part of the System pro M compact S200 range, known for its reliability and compliance with international standards such as IEC/EN 60898-1, IEC/EN 60947-2, and UL1077. Suitable for residential, commercial, and industrial applications, the S203-B50 is available in multiple configurations, characteristics, and rated currents up to 63A. Its compact design allows for auxiliary contacts to be fitted at the bottom, saving up to 50% space.
