Rated for up to 600 VAC maximum, this unit trips on overcurrent and requires a manual reset to restore operation, making it suited for applications where a deliberate reset is required after an overload event. The SER.K variant identifies the specific series within the 815 family, and the size-4 designation indicates its current-protection class within compatible AB motor starters. Designed to work with compatible Allen-Bradley contactors and starter assemblies, it is commonly used to safeguard AC motors in conveyors, pumps, fans, and other industrial equipment powered from standard industrial voltages. As an integral component of AB motor-control protection, this 815-E0V4 unit offers discrete, replaceable protection that helps prevent motor damage due to overloads while simplifying maintenance and replacement in legacy or retrofit installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657437184302,"sku":null,"price":54.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_59c9eefc-fe82-44ac-a690-715b3a85b03e.jpg?v=1769468960","url":"https:\/\/plgautomation.com\/products\/allen-bradley-815-e0v4-usnt-industrial-relay-module","provider":"PLG Automation ","version":"1.0","type":"link"}
