The DCNLEV50-ES 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), polarized load terminals, and a side-mount configuration. It supports a continuous current of 50 A and a voltage rating of 750 V DC, with SPST-NO contacts and IP67 ingress protection. The device operates from -40 to 85°C, mounts via M4 bolts with 2.3 Nm torque, and has terminals with M5 silver-plated copper connections. The contactor is sealed with gas to mitigate arcing, complies with UL File No. E510407, and is manufactured under IATF16949. Dimensions are 46 mm × 58 mm × 41 mm, and it weighs 0.19 kg.
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-ES) features a 48 V coil and polarized contacts. In addition, the 50 A relay has a side mounting style.
