Why Choose the ABB ST201M-C0.5 Miniature Circuit Breaker?
The ABB ST201M-C0.5 is a compact and reliable single-pole miniature circuit breaker (MCB) designed to provide supplementary overcurrent and short-circuit protection for low-current industrial electrical, control and automation circuits. As part of the proven ABB ST200M miniature circuit breaker series, it combines a C tripping characteristic with a rated current of 0.5 A for dependable protection of sensitive low-current circuits.
Designed for industrial control panels, machinery and automation equipment, the ST201M-C0.5 provides thermal-magnetic protection against overload and short-circuit conditions. Its C characteristic accommodates moderate inrush currents while maintaining effective circuit protection, making it suitable for control equipment, instrumentation, auxiliary circuits and other low-current industrial loads.
With a 1-pole configuration, 0.5 A rated current and 15 kA short-circuit breaking capacity under applicable IEC conditions, the ST201M-C0.5 provides robust protection in a compact DIN rail format. The device is designed for UL 1077 supplementary protection, supporting straightforward integration into industrial equipment and electrical control systems.

Reliable Supplementary Circuit Protection
Miniature circuit breakers such as the ABB ST201M-C0.5 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 C tripping characteristic provides a practical balance between overload protection and tolerance of normal starting currents. Combined with its low 0.5 A rating, this makes the ST201M-C0.5 particularly suitable for auxiliary, instrumentation and control circuits where low-current protection and tolerance of moderate transient currents are required.
Typical Applications
- Industrial electrical control panels.
- Machine building and factory automation systems.
- Instrumentation and measurement circuits.
- Low-current control and auxiliary circuits.
- Automation and process control equipment.
- Supplementary protection for industrial electrical equipment.
