It can be used\n    on 95-120VAC (201-100-SP) or 190-240VAC (201-200-SP) motors to prevent\n    damage caused by low voltage. High voltage detection is included on the\n    201-200-SP-T-9 model. The unique microcontroller-based voltage and\n    voltage-sensing circuit constantly monitors the voltage to detect harmful\n    power line conditions. When a harmful condition is detected, the\n    MotorSaver's output relay is deactivated after a specified trip delay. The\n    output relay reactivates after power line conditions return to an\n    acceptable level and specified amount of time has elapsed (restart delay).\n    The trip delay prevents nuisance tripping due to rapidly fluctuating power\n    line conditions.\n\u003c\/p\u003e\n\u003ch3\u003e\nLittelfuse 201-100-SP Voltage Monitor Typical Applications\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFans\n\t\u003c\/li\u003e\n\u003cli\u003eCompressors\n\t\u003c\/li\u003e\n\u003cli\u003eAir Conditioners\n\t\u003c\/li\u003e\n\u003cli\u003eHeat Pumps\n\t\u003c\/li\u003e\n\u003cli\u003eWell Pumps\n\t\u003c\/li\u003e\n\u003cli\u003eSump Pumps\n\t\u003c\/li\u003e\n\u003cli\u003eSmall Conveyor Motors\n\t\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\nLittelfuse 201-100-SP Voltage Monitor Features\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLow Voltage Protection\n\t\u003c\/li\u003e\n\u003cli\u003eLow \u0026amp; High Voltage Protection Model Available\n\t\u003c\/li\u003e\n\u003cli\u003eDiagnostic LED\n\t\u003c\/li\u003e\n\u003cli\u003eUL508 Listed\n\t\u003c\/li\u003e\n\u003cli\u003eCE Marked\n\t\u003c\/li\u003e\n\u003cli\u003e8-Pin Plug In; DIN Rail or Surface Mount\n\t\u003c\/li\u003e\n\u003cli\u003e5-Year Warranty\n\t\u003c\/li\u003e\n\u003cli\u003eMade in USA\n\t\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Littelfuse\/Symcom","offers":[{"title":"Default Title","offer_id":49317861097789,"sku":"MSR201100SP","price":167.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/5552\/7485\/files\/msrlf201xxxsp_001_wbg.jpg?v=1725295641"},{"product_id":"littelfuse-201a-three-phase-voltage-monitor","title":"Littelfuse 201A Three-Phase Voltage Monitor","description":"\u003cp\u003e\u003cimg data-image=\"mbalmfpxeg3y\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0857\/5552\/7485\/files\/littelfuse1_logo.jpg\" title=\"Littelfuse your electronic and control \u0026amp; protection specialists\"\u003e\u003c\/p\u003e\n\u003ch3\u003eLittelfuse 201A Voltage Monitor Product Description\u003c\/h3\u003e\n\u003cp\u003eThe 201A is a 3-phase, auto-ranging, dual-range voltage monitor that protects 190-480 V ac, 50\/60 Hz motors regardless of size.

A microcontroller-based relay that monitors the shaft seal of a submersible pump motor. A resistive probe is installed in the seal cavity. If water leaks into the pump, the resistance measured by the probe decreases. When the resistance drops below the sensitivity setpoint, the unit will trip and the relay contacts will change state.
