This Boltswitch model monitors voltage, phase unbalance, and trip delay for industrial and commercial applications. The unit features front-mounted adjustment pots and LED indicators for voltage, unbalance, and time delay, making setup and troubleshooting easy. It is suitable for systems operating at 480VAC nominal voltage. The PLVR-480 provides automatic reset and has a trip delay adjustment range of 1 to 10 seconds in 1-second increments. The relay offers a voltage adjustment range of 336–456VAC and an unbalance adjustment range of 2 to 10% per NEMA specifications. Power consumption is 4.5W per phase, and the output contacts are rated DPDT with 40 amps at 28VDC\/300VAC and 5 amps at 480\/600VAC. The operating temperature range is -4º to +131º F, and the unit is designed for panel or DIN rail mounting. \u003cul\u003e \u003cli\u003ePart Number: PLVR-480\u003c\/li\u003e \u003cli\u003eManufacturer: Boltswitch\u003c\/li\u003e \u003cli\u003eType: Phase Failure Relay\u003c\/li\u003e \u003cli\u003eVoltage: 480VAC nominal\u003c\/li\u003e \u003cli\u003ePoles: 3\u003c\/li\u003e \u003cli\u003eMounting: Panel or DIN rail\u003c\/li\u003e \u003cli\u003eAdjustable Trip Delay: 1–10 seconds\u003c\/li\u003e \u003cli\u003eUnbalance Adjustment: 2–10% per NEMA\u003c\/li\u003e \u003cli\u003eOutput Contacts: DPDT 40A @ 28VDC\/300VAC, 5A @ 480\/600VAC\u003c\/li\u003e \u003cli\u003ePower Consumption: 4.5W per phase\u003c\/li\u003e \u003cli\u003eOperating Temperature: -4º to +131º F\u003c\/li\u003e \u003cli\u003eReset Type: Automatic\u003c\/li\u003e \u003c\/ul\u003e At \u003cb\u003eEssential Parts\u003c\/b\u003e, we offer \u003cb\u003efast shipping\u003c\/b\u003e, \u003cb\u003elowest price\u003c\/b\u003e, and \u003cb\u003eexpert support\u003c\/b\u003e to help you get the right product every time. \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: PLVR-480\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Boltswitch\u003c\/li\u003e\n\u003cli\u003eBrand : Boltswitch\u003c\/li\u003e\n\u003cli\u003eCategory : Switch\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Parts \u0026amp; Accessories\u003c\/li\u003e\n\u003cli\u003eSection  : Relays\u003c\/li\u003e\n\u003cli\u003eFamily : Model PLVR\u003c\/li\u003e\n\u003cli\u003eType : PLVR\u003c\/li\u003e\n\u003cli\u003eCompatible Frames : SFHA\u003c\/li\u003e \t\t\t\t\t\t\t\t\t\t\u003c\/ul\u003e                                         \u003cbr\u003e                                         \u003ch3\u003e\u003cb\u003eProduct Data\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWeight : 2 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Boltswitch","offers":[{"title":"New","offer_id":44429549174943,"sku":"PLVR-480-New","price":1385.32,"currency_code":"USD","in_stock":true}],"url":"https:\/\/essentialparts.com\/products\/plvr-480","provider":"Essential Electric Supply","version":"1.0","type":"link"}
