Why Choose the ABB ST201M-D63 Miniature Circuit Breaker?
The ABB ST201M-D63 is a compact and dependable single-pole miniature circuit breaker (MCB) designed for supplementary overcurrent protection in industrial control equipment and electrical systems. As part of the ABB ST200M series, it combines a 63 A rated current with a D tripping characteristic and compliance with UL 1077 for supplementary protectors.
The ST201M-D63 provides thermal-magnetic protection against overload and short-circuit conditions. Its D characteristic is suited to circuits containing equipment with high starting or inrush currents, allowing normal transient currents while providing rapid magnetic disconnection under severe fault conditions.
With a 63 A rated current, single protected pole and 15 kA short-circuit breaking capacity, the ST201M-D63 provides robust supplementary protection in a compact modular format. Its DIN-rail construction enables straightforward integration into industrial machinery, control panels and OEM electrical assemblies.
