ABB ST201M-C8 Safety Relay

ABB ST201M-C8 is a one-pole miniature circuit breaker from ABB’s ST200M System pro M Compact family, rated for 8 A and designed to protect single‑phase circuits up to 480Y/277 V AC with a 10 kA short-circuit current rating. It uses a C‑curve (Type C) trip characteristic, providing reliable overcurrent protection against both overloads and short circuits in branch circuits within commercial or light‑industrial panel boards and control circuits. The device is UL 1077‑listed and RoHS compliant, aligning ABB’s safety standards with environmental requirements. As part of ABB’s ST200M line, the ST201M-C8 is intended for compact installations in System pro M Compact assemblies, offering predictable tripping performance and straightforward integration with other components in ABB’s modular protection ecosystem. This model’s 1P configuration supports single‑pole protection, making it suitable for smaller distribution tasks where space and simplicity are priorities while still delivering the rated protection against electrical faults.
