The unit features adjustable settings for voltage monitoring, unbalance detection, and trip delay. All adjustment controls and LED indicators for voltage, unbalance, and time delay are mounted on the front panel for convenient field access. The relay operates across a nominal voltage range of 208 to 240 VAC at 50\/60 Hz frequency and includes manual reset capability with a nominal reset time of 150 milliseconds.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNominal Voltage: 240 VAC\u003c\/li\u003e\n\u003cli\u003eFrequency: 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003eUnder Voltage Range: 168-229V\u003c\/li\u003e\n\u003cli\u003eUnbalance Adjustment Range: 2 to 10 percent per NEMA specifications\u003c\/li\u003e\n\u003cli\u003eTrip Delay Adjustment Range: 1 to 10 seconds in 1 second increments\u003c\/li\u003e\n\u003cli\u003ePower Consumption: 4.5W per phase\u003c\/li\u003e\n\u003cli\u003eRepeat Accuracy: Plus or minus 1 percent of full scale\u003c\/li\u003e\n\u003cli\u003eReset Time: 150 ms nominal\u003c\/li\u003e\n\u003cli\u003eFront-mounted adjustment potentiometers and LED indicators\u003c\/li\u003e\n\u003cli\u003eDetects phase loss, phase reversal, and phase unbalance conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAt \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.\u003c\/p\u003e \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: PM-240\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  : Misc.
