The underpower trip feature is desirable anytime the current vs. load characteristic is non-linear or has little change. In general terms, smaller motors and slow-speed motors have little change in current over the normal load range. Larger motors that are running light loads will also show small current changes over the operating load range. Common uses include pumping applications where motors run slower than around 3400 rpm and usually have small current vs load changes; such as slow speed mixer or agitator motors up to 50 hp, and magdrive or can pumps.

The underpower trip feature is desirable anytime the current vs. load characteristic is non-linear or has little change. In general terms, smaller motors and slow-speed motors have little change in current over the normal load range. Larger motors that are running light loads will also show small current changes over the operating load range. Common uses include pumping applications where motors run slower than around 3400 rpm and usually have small current vs load changes; such as slow speed mixer or agitator motors up to 50 hp, and magdrive or can pumps. The Littelfuse PumpSaver® relay provides the high sensitivity of a power monitor to protect pump motors from dry run and deadhead conditions.\u003c\/p\u003e\n\u003cp\u003eSmall motors, those under 3 hp and especially fractional horsepower, exhibit small changes in current vs. load, but the change in power is large. When larger motors are derated (run below their rated horsepower) the change in current is small vs. load, but again, the change in power is large and linear. Other typical applications include slower speed mixer or agitator motors up to 50 hp and beyond.

A unique microcontroller-based voltage and current-sensing circuit constantly monitors the incoming power for fluctuations, overcurrent, and undercurrent. When an abnormality, such as loss of suction is detected, the product deactivates its output relay and directly disconnects the pump motor. The relay then begins its user-selectable restart delay (dry-well recovery) timer. When the timer counts to zero or power is removed and reapplied, the relay reactivates its output relay and turns the pump back on. By leaving the restart delay knob in the reset position, the relay will operate in manual reset mode.\u003c\/p\u003e\n\u003cp\u003eThe Insider communicates with a hand-held diagnostics tool called the Informer (sold separately). The Informer displays parameters including calibration points, trip points, run time and last faults. An IR Kit-12 (12” fiber optic kit) is included with each Insider, allowing the Informer to access these parameters even when the Insider is enclosed in a control box.

A calibration adjustment allows the 235P to be calibrated to your specific pumping applications, thereby reducing the possibility of false or nuisance tripping. A unique microcontroller based voltage and current-sensing circuit constantly monitors the incoming power for fluctuations causing overcurrent and undercurrent. When an abnormality, such as loss of suction is detected, the 235P deactivates its output relay and directly disconnects the pump motor.\u003c\/p\u003e\n\u003ch3\u003eLittelfuse 235P PumpSaver Plus Typical Application\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWell Pump\u003c\/li\u003e\n\u003cli\u003eReservoir Pump\u003c\/li\u003e\n\u003cli\u003eTransfer Pump\u003c\/li\u003e\n\u003cli\u003eSewage Pump\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eLittelfuse 235P PumpSaver Plus Technical Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes NEMA 3R Enclosure\u003c\/li\u003e\n\u003cli\u003e50:5 CT Required for 5-7.5 HP\u003c\/li\u003e\n\u003cli\u003e75:5 CT Required for 10 HP\u003c\/li\u003e\n\u003cli\u003e100:5 CT Required for 15 HP\u003c\/li\u003e\n\u003cli\u003eProtect Single Phase Pumps From the Following Conditions: Run Dry, Dead Head, Jammed Impeller, Rapid-Cycle, Overvoltage, and Undervoltage\u003c\/li\u003e\n\u003cli\u003e230 Volt, Single Phase\u003c\/li\u003e\n\u003cli\u003e5 - 15 HP Pumps\u003c\/li\u003e\n\u003cli\u003eCalibrated for Specific Pumping Applications\u003c\/li\u003e\n\u003cli\u003eAutomatic Timeout and Pump Restart\u003c\/li\u003e\n\u003cli\u003eIdeal for Submersible Pumps\u003c\/li\u003e\n\u003cli\u003eState-of-the-Art Pump Protection\u003c\/li\u003e\n\u003cli\u003eInfrared LED Communication to SymCom’s Informer\u003c\/li\u003e\n\u003cli\u003eUL Listed\u003c\/li\u003e\n\u003cli\u003e5-Year Warranty\u003c\/li\u003e\n\u003cli\u003eMade in US\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Littelfuse\/Symcom","offers":[{"title":"Default Title","offer_id":49325286457661,"sku":"MSR235PENCL","price":463.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/5552\/7485\/files\/symcom233_incl_w_6b7f92d1-3164-4bb7-99d5-ea80d94683c0.jpg?v=1725426599"},{"product_id":"littelfuse-777-mrsw-manual-remote-reset-switch-kit-for-model-777","title":"Littelfuse 777-MRSW Manual Remote Reset Switch Kit for Model 777","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\u003cp\u003e\u003c\/p\u003e\n\u003ch3\u003e\nLittelfuse 777-MRSW Manual Remote Reset Switch Kit Product Description\u003c\/h3\u003e\n\u003cp\u003e777 Manual Remote Reset Kit (24 inches long)\nallows the 777 line of MotorSaver® and PumpSaver® products to be manually reset without opening\nthe panel door.
