  • Electrical Protection Relays, Overload / Underload Protection Relays, Pump Protection Relays

    Pump-Monitor: 3 Phase Motor & Pump Protection Relay

    Electronic overload relay that protects three-phase motors and pumps from 1 to 300 H.P. against overload, phase failure, rapid cycling, and low water level without the need for electrodes (low load). The display allows for easy adjustments and shows the three line currents, maximum current, and faults.

  • Electrical Protection Relays, Overload / Underload Protection Relays, Pump Protection Relays

    Pump-Monitor: Single Phase Motor & Pump Protection Relay

    Electronic overload relay that protects single-phase pumps and motors from overload, rapid cycling, high/low voltage, and low water level (low load) without the need for electrodes. The screen displays voltage, current, power, and faults.

  • Electrical Protection Relays, Overload / Underload Protection Relays, Pump Protection Relays, Voltage Protection Relays

    Motor Monitor®: Voltage and Current Fault Protection Relay

    Protects motors and pumps against low and high voltage, phase failure, imbalance, reverse rotation, overload, underload, low suction, frequent starts, and more. Its display shows voltages, currents, faults, and settings.
