NK Technologies ASXP Series AC Current Operated Switches with Time Delay, SmartLED, 1 - 50 A Adjustable Setpoint Range

The 'ASXP' from NK Technologies is a powered version of our popular current switch with integral time delay series. A fixed two-second delay upon trip minimizes nuisance alarms during start-up and operation in motor or heater status applications.  For use with 24VAC/DC or 120VAC supplies, this high performance product offers OEM-caliber accuracy, precision tolerances, low hysteresis and low (non-sinusoidal) frequency operation. Available with status LED and solid-core enclosure as standard.

Motor Protection

  • Serves as an electronic proof-of-operation; detects current draw changes in motors when they encounter problems such as pumps running dry or pending bearing failure. Non-intrusive, less expensive to install than differential pressure flow sensors or thermal switches. Much quicker response time than Class 10 overload relays

    • High Inrush or Temporary Overload Current

  • Start-up/delay timer provides 2 second delay to avoid nuisance tripping from high inrush or short overload conditions

      • No accessories available
