Why Choose the ABB ST201M-B63 Miniature Circuit Breaker?
The ABB ST201M-B63 is a high-performance single-pole miniature circuit breaker (MCB) designed to provide reliable supplementary overcurrent and short-circuit protection in industrial electrical, machinery and automation systems. As part of the robust ABB ST200M miniature circuit breaker series, it combines a B tripping characteristic with a rated current of 63 A in a compact modular format.
Designed for supplementary circuit protection, the ST201M-B63 provides thermal-magnetic protection against overload and short-circuit conditions. Its B characteristic offers a relatively sensitive instantaneous trip response, making it suitable for circuits with low inrush currents, including resistive loads, control circuits and other industrial electrical equipment.
With a rated current of 63 A, a 1-pole configuration and a rated ultimate short-circuit breaking capacity of 15 kA at 230 V AC according to IEC/EN 60947-2, the ST201M-B63 provides dependable protection in demanding installations. Its DIN rail format enables straightforward integration into industrial control panels, machinery cabinets and electrical distribution assemblies.

Reliable Supplementary Circuit Protection
Miniature circuit breakers such as the ABB ST201M-B63 protect electrical circuits and connected equipment against excessive current caused by overload and short-circuit conditions. The thermal-magnetic operating mechanism automatically interrupts the circuit when defined trip conditions are reached and allows the breaker to be reset after the fault has been safely cleared.
The B tripping characteristic is well suited to circuits where normal operation produces relatively low starting or inrush currents. This makes the ST201M-B63 suitable for resistive loads, control circuits and industrial electrical equipment requiring a more sensitive instantaneous magnetic trip characteristic.
Typical Applications
- Industrial electrical control panels.
- Machine building and factory automation systems.
- Resistive electrical loads.
- Industrial control and auxiliary circuits.
- Machinery and production equipment.
- Electrical distribution and supplementary circuit protection.
