Why Choose the ABB ST201M-Z2 Miniature Circuit Breaker?
The ABB ST201M-Z2 is a high-performance single-pole miniature circuit breaker (MCB) / supplementary protector designed to provide reliable overload and short-circuit protection in industrial control, automation and equipment circuits. With ABB order code 2CDS271334R0278, it forms part of the ABB ST 200 M series of modular circuit protection devices.
Designed for applications requiring sensitive overcurrent protection in a compact DIN-rail format, the ST201M-Z2 combines thermal and magnetic tripping to protect electrical equipment and conductors against overload and short-circuit conditions. Its Z tripping characteristic provides rapid magnetic response and is particularly suited to sensitive circuits and equipment where fault currents need to be interrupted quickly.
The ST201M-Z2 has a rated current of 2 A, a single-pole configuration and a 15 kA short-circuit breaking capacity. Its UL 1077 classification supports use as a supplementary protector within electrical equipment, making it well suited to low-current industrial control, automation and electronic equipment applications.

Sensitive Circuit Protection for Industrial Systems
Miniature circuit breakers such as the ABB ST201M-Z2 provide automatic protection against overload and short-circuit conditions. When current exceeds the permitted operating range, the thermal-magnetic tripping mechanism disconnects the protected circuit, helping protect wiring and connected electrical equipment from damaging overcurrent conditions.
The ST 200 M series is designed for industrial applications where compact modular protection and dependable switching performance are required. The ST201M-Z2's 2 A rating and Z tripping characteristic make it particularly useful for sensitive low-current circuits requiring a comparatively fast magnetic response, while its UL 1077 classification supports supplementary protection within electrical equipment.
Typical Applications
- Industrial control panels and automation systems.
- Low-current machine control and auxiliary circuits.
- Sensitive electronic and control equipment.
- Control, signalling and instrumentation circuits.
- Supplementary protection within electrical equipment.
- Industrial machinery and DIN-rail control assemblies.
