ABB ST201M-K10 Safety Relay Module For Industrial Control Systems

ABB ST201M-K10 is a 1-pole miniature circuit breaker from ABB's System pro M compact ST200M family, delivering 10 A of continuous current with a Type K trip characteristic. It provides thermal-magnetic protection for low‑voltage control circuits and small loads in industrial panels, preventing overloads and short circuits and enabling safe machine shutdown during faults. The device has a short-circuit breaking capacity of 10 kA (Icn) and carries UL 1077 listing, signifying suitability as a supplementary protector in North American electrical installations. As a member of the ST200M platform, the ST201M-K10 is designed for compact protection solutions in control cabinets and automation cells, offering straightforward compatibility with other System pro M compact devices. This model is specified as a 1-pole, 10 A unit with a K-characteristic curve, making it appropriate for circuits with moderate inrush and fast fault clearing in industrial environments. Typical applications include protecting control circuits, sensors, actuators, and auxiliary loads in machinery, packaging lines, and automated equipment where dependable overcurrent protection is required. With ABB’s ST200M family backing it, the ST201M-K10 provides a consistent protection strategy across a modular protection lineup, helping maintain safe operation and simplifying panel design and maintenance.
