Low trip delay is ideal in chain drive and drive\nlinkage applications to prevent breaking in overload or jam situations. Other applications include\nsewage clarifiers, mixers, augers, and conveyors. Longer trip delay is ideal for motor test panels\nin rewind shops. Also includes adjustable motor acceleration time and overcurrent trip delay\ntime when the faster linear trip mode is used.\n\u003c\/p\u003e\n\u003ch3\u003e\nLittelfuse 777-FT Pump Monitor Typical Application\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConveyor Systems\n\t\u003c\/li\u003e\n\u003cli\u003eHVAC Equipment\n\t\u003c\/li\u003e\n\u003cli\u003eSaws and Grinders\n\t\u003c\/li\u003e\n\u003cli\u003eFan Motors\n\t\u003c\/li\u003e\n\u003cli\u003eAll Pumping Applications With Single-Phase Electric Motors\n\t\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\nLittelfuse 777-FT Pump Monitor Technical Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e      Protects 3-Phase Motors From:\n\t\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003eOverload\n\t\t\u003c\/li\u003e\n\u003cli\u003eUnderload\n\t\t\u003c\/li\u003e\n\u003cli\u003eJambs\n\t\t\u003c\/li\u003e\n\u003cli\u003eUnder Voltage\n\t\t\u003c\/li\u003e\n\u003cli\u003eOver Voltage\n\t\t\u003c\/li\u003e\n\u003cli\u003eSingle Phasing\n\t\t\u003c\/li\u003e\n\u003cli\u003eUnbalance (voltage \u0026amp; current)\n\t\t\u003c\/li\u003e\n\u003cli\u003eGround Fault (class II)\n\t\t\u003c\/li\u003e\n\u003cli\u003eRapid Cycling\n\t\t\u003c\/li\u003e\n\u003cli\u003ePhase Reversal\n\t\t\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eFully Programmable\n\t\u003c\/li\u003e\n\u003cli\u003eAutomatic Reset With Three Separate Restart Delay Timers, or Manual\n    Reset\n\t\u003c\/li\u003e\n\u003cli\u003eTamper Guard\n\t\u003c\/li\u003e\n\u003cli\u003eRS-485 Communications Port (Communications Module Sold Separately)\n\t\u003c\/li\u003e\n\u003cli\u003e3-digit LED Diagnostic Display\n\t\u003c\/li\u003e\n\u003cli\u003eRemote Reset\n\t\u003c\/li\u003e\n\u003cli\u003eLast Fault Memory\n\t\u003c\/li\u003e\n\u003cli\u003eUL and cUL Listed\n\t\u003c\/li\u003e\n\u003cli\u003eCE Compliant\n\t\u003c\/li\u003e\n\u003cli\u003eCSA Approved\n\t\u003c\/li\u003e\n\u003cli\u003eSurface or DIN Rail 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":49317638668605,"sku":"MSR777FT","price":985.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/5552\/7485\/files\/msr777_001_wbg_1d322209-4ab9-449b-b404-91ce55f09949.jpg?v=1725291574"},{"product_id":"littelfuse-777-hvr-p2-pump-monitor-overload-relay-340-480v-3-phase-2-800fla-plus","title":"Littelfuse 777-HVR-P2 Pump Monitor Overload Relay 340-480V 3-Phase 2-800FLA Plus","description":"\u003cp\u003e\n\u003cimg data-image=\"1l9tsjtw0igc\" 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\n\u003c\/p\u003e\n\u003ch3\u003e\nLittelfuse Model 777-HVR-P2 Pump Monitor Product Description\u003c\/h3\u003e\n\u003cp\u003e\n\tThe 777 is a fully programmable electronic overload relay\ndesigned to protect any motor drawing 2-800 full load amps\n(external CTs are required above 90 amps).

For standalone applications, the units\nincorporate a 3-digit LED display that is used for programming,\nproviding real-time operational information and displaying\ndiagnostic codes to aid in troubleshooting a fault condition. The\nunits also feature a communications port that can be used with\ncommunication modules listed in the 777 accessories section to\nform a Modbus, DeviceNet*, Profibus, or Ethernet network. Up\nto 99 units can be remotely monitored and controlled from a PC,\nPLC, or SCADA system, and data logging through a PC with the\noptional Solutions software. This capability allows for a simple,\ncost-effective way to meet new requirements for arc-flash safety.\n\u003c\/p\u003e\n\u003cp\u003e\n\tModel 777-TS provides 480 VA @ 240 V ac output SPDT relay contacts.
