JEVB500 Series features

  • 500 A current rating
  • Bidirectional switching device
  • A simple solution for applications that require charging and discharging because it safely cuts off the current flowing through the main contact in the opposite direction
  • UL508 listed for the U.S. and Canada
  • RoHS compliant
  • Hermetically sealed, intrinsically safe, operates in explosive/harsh environments with no oxidation or contamination of coils or contacts during long periods of non-operation
  • Rugged, compact contactor for switching voltages from 50 VDC to 1000+ VDC
  • High-efficiency DC coils – Very low 12 and 24 VDC continuous power coils with no EMI emissions or cross-talk on your system control power
