460 MotorSaver

460 SymCom MotorSaver - In Stock
Is designed to protect 3-phase loads from damaging power conditions. The 460's wide operating range of voltages, combined with UL and CE compliance, makes this a perfect choice for your motor's protection. This is a must have device for applications where power supply quality is uncertain. This premium quality and cost-effective protection device is an alternative from high replacement costs of your electric motor.

MotorSavers unique microcontroller-based voltage and phase-sensing circuit constantly monitors the 3-phase voltages to detect harmful power line conditions.When a harmful condition is detected, the MotorSaver's output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to an acceptable level for a specified amount of time (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.

  • Protects 3-Phase Motors From:
    • Low voltage
    • High voltage
    • Loss of any phase
    • Voltage unbalance
    • Rapid cycling

460 MotorSaver automatically senses whether it is connected to a 190-240V, 60Hz system, a 440-480V, 60Hz system, or a 380-416V, 50Hz system. An adjustment is provided to set the nominal line voltage from 190-240 or 380-480VAC. Other adjustments include a 1-30 second trip delay, 1-500 second restart delay, and 2-8% voltage unbalance trip point.

  • The 460’s universal range from 190-480VAC, 50/60 Hz provides the versatility needed to handle global applications.
  • Four adjustment pots provide versatility for all kinds of applications.
  • Diagnostic LEDs indicate trip status and provide simple troubleshooting.
  • Microcontroller-based circuitry provides better accuracy and higher reliability than analog designs.
  • Transient protection meets IEEE and IEC standards to allow operation under tough conditions.
  • Standard surface or DIN rail mountable
  • One 10 Amp general purpose Form C relay
  • UL and cUL listed
  • CE compliant
  • 5-year warranty
  • Made in USA

Great V
Submitted by Al Andrews on
I have used these for years on sewage pump stations. I have saved quite a few motors that would have been damaged or destroyed due to single-phasing and out of spec power - especially because of thunderstorms. We have also found 3-phase problems, upon power returning, that would have motors running backwards and very poor pumping. But, the motor saver told us the problem right away. Great unit & highly reliable !!!
