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.

This configuration of the DCNLEV50 series electric vehicle contactor (DCNLEV50-EN) features a 48 V coil and non-polarized contacts. In addition, the 50 A relay has a bottom mounting style.
