ABB ST201M-B10 Safety Relay Module 2-Channel 24V DC

ABB ST201M-B10 is a 1-pole miniature circuit breaker from ABB’s ST200M family, rated at 10 A with a B-type (characteristic B) trip curve. It is UL 1077-listed and designed to provide overcurrent protection for individual circuits in electrical distributions, commonly used in panelboards and control cabinets across commercial and light industrial installations. The North American variant ST201M-B10NA extends the same 10 A, B-curve profile to include a 60 V DC rating, making it suitable for DC control and power circuits within that regional specification. These ABB ST200M devices offer compact, reliable protection for single‑phase circuits in DIN-rail mounted distributions and other ABB protection solutions.
