It provides thermal overload protection with a trip range of 45–65 A, guarding against motor damage from overloads, phase failure, and long starting times or stalling in AC-3 service. The device includes a pair of auxiliary contacts—a normally open and a normally closed contact—for signaling and for interrupting the coil to shut the starter down when protection is activated. As part of the RMSO\/SPO family, the SPO-85-55A delivers reliable, mechanical overload protection with straightforward integration into standard low-voltage motor-control schemes and works with Benshaw control products to maintain consistent protection across the drive system.\u003c\/p\u003e\u003c\/div\u003e","brand":"BENSHAW","offers":[{"title":"New","offer_id":51676891644206,"sku":null,"price":87.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9c7217f8-17da-4cd3-8446-137c166d30e7.jpg?v=1769554853","url":"https:\/\/plgautomation.com\/products\/benshaw-spo-85-55a-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
