It is rated for 4 A and 240 V AC, with catalog-listed ratings of 277 V AC and 60 V DC, making it suitable for mixed-power and DC-control applications. The device provides a 10 kA short-circuit breaking capacity (UL 1077), enabling reliable interruption at fault currents. As part of ABB's System Pro M Compact family, the ST201M-C4 mounts on a standard DIN rail and offers a compact, single-pole protection solution for enclosures and control panels. The catalog number is 2CDS271334R0044, confirming 1P, C-characteristic, 4 A rating, and 10 kA Icu. Typical applications include protection of control circuits, relays, contactors, solenoids, lighting feeders, and small automation loads in industrial environments. This model is used where standard safety and coordination requirements call for a reliable 1-phase protection device with a moderate let-through current, ensuring selective protection for upstream devices while enabling straightforward wiring in 230\/240 V systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656724447534,"sku":null,"price":41.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_7f31ec92-64bf-4072-ac5d-589085708db9.jpg?v=1769462961","url":"https:\/\/plgautomation.com\/products\/abb-st201m-c4-safety-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
