It features a MCOV of 660 V AC and a voltage protection rating (VPR) of 1.9 kV, a response time under 25 ns, and supports protection modes L-N, L-G, N-G and L-L, while including an integrated thermal disconnector, a state indicator, and a remote indicator. Disconnection options include a J-class fuse up to 100 A or a circuit breaker with B- or C-curve ratings up to 125 A, and the device requires upstream protection with an SCCR rated at 200 kAIC. Designed for 47–63 Hz operation and compatible with replacement cartridges such as OVRT240550CU, the OVRT240550PTSU guards 480 V delta networks against transient overvoltages to safeguard connected equipment.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656749089070,"sku":null,"price":171.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e09e4c79-33ca-4ff3-8f64-37a158705f38.jpg?v=1769463177","url":"https:\/\/plgautomation.com\/products\/abb-ovrt240550ptsu-overvoltage-protection-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
