The DCNLEV50 Series 750 V 50 A High-Voltage DC Contactor Relay is designed for electric vehicle (EV) and eMobility applications, including battery power supply, charging station, motor control, circuit protection, and other switch controls as well as industrial machinery applications.

The magnetic arc blowout design in an IP67 sealed, gas-filled chamber dissipates electrical arc between the contacts. This design allows the automotive relay to safely make/break higher voltages.

The DCNLEV50 series electric vehicle contactor is available with a 12 V, 24 V, or 48 V coil rating, with or without an auxiliary contact, and with side or bottom mounting. In addition, the 50 A relay can be ordered with either polarized or non-polarized contacts to optimize for your electrical system load polarity.

Features and Benefits

  • High-voltage (750 V) contactor with a continuous current rating of 50 A for electric vehicle (EV) and eMobility applications
  • Compact structure helps reduce noise when the contactor is turned on
  • Magnetic arc blowout design dissipates arc within an IP67 sealed, gas-filled chamber, allowing the relay to make/break higher voltages
  • Lightweight actuator is less impacted by gravity with no mounting orientation restrictions
  • Designed and manufactured under the IATF16949 certification for Automotive Quality Systems
  • Automotive relay features single-pole, single-throw (SPST) circuitry
  • Polarized and non-polarized contact design options that optimize performance depending on electrical system load polarity

Applications

  • Battery Electric Vehicles (BEV)
  • Hybrid Electric Vehicles (HEV)
  • Material Handling
  • Electric Maintenance and Transport Vehicles
  • Industrial
