ABB ST201M-C2 Safety Relay Module 24V DC Industrial Grade

ABB ST201M-C2 is a 1-pole miniature circuit breaker from ABB's System Pro M Compact ST200M family, designed for DIN-rail mounting in industrial control panels. It is rated for 2 A and up to 60 V DC, delivering reliable overcurrent protection for DC control circuits and small power distributions in automation environments. This C-curve device combines thermal and magnetic trip elements to guard against both overloads and short circuits, with a rated short-circuit breaking capacity (Icu) of 10 kA. The compact, single-pole form factor simplifies panel layouts and enables easy integration with other protection devices in modular switchgear. The ST201M-C2 is typically used to protect DC circuits within industrial equipment, ensuring safe disconnection during fault conditions while meeting UL 1077 recognition in applicable markets. With DIN-rail mounting and ABB’s reputation for robust electrical protection, this model provides predictable response and reliable protection in compact control enclosures. When selecting protection for a DC network, consider this 1P, 2 A, 60 V DC MCB for circuits where a fast, dependable disconnection on fault conditions is required and space on the DIN rail is at a premium. The ST201M-C2 complements broader ST200M offerings for coordinated protection in panel builders and machine builders alike.
