The DCNLEV50-ESN is a high-current, high-voltage DC contactor relay designed for electric vehicle and industrial applications, featuring a 48 V DC nominal coil (33-52 V DC working range), non-polarized load terminals, and side mounting. It has a 50 A continuous current rating, 750 V DC voltage rating, and SPST-NO contact arrangement. The relay is sealed to IP67, operates from −40 °C to 85 °C, and has a compact size of 46 mm × 58 mm × 41 mm with M4 mounting and M5 silver-plated copper terminals. It is UL recognized (File No. E510407) and manufactured under IATF16949 for automotive applications.
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-ESN) features a 48 V coil and non-polarized contacts. In addition, the 50 A relay has a side mounting style.
