The official ABB catalog reference is 1SFA611525R1101, and this variant is non-illuminated, relying on its conspicuous red color and large mushroom actuator rather than LEDs to signal an emergency stop. The unit ships without a contact block, so you’ll pair it with a compatible block as needed to complete the control circuit. It features a key-release mechanism, meaning the stop can only be reset with the supplied key, adding tamper-resistance in safety-critical environments. Suitable for safety circuits in industrial machinery and equipment that require a fail-safe stop, the MPEK4-11R is a robust option when a non-illuminated emergency stop with key-release is desired.\u003c\/p\u003e\n\u003cspan class=\"citation\"\u003e \u003c\/span\u003e\n\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656770355502,"sku":null,"price":822.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c7634ffe-9fdf-421b-92b9-37f1bdfb7a78.jpg?v=1769463341","url":"https:\/\/plgautomation.com\/products\/abb-mpek4-11r-electronic-motor-protection-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
