The DCNLEV50-EN 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 operating range) and non-polarized load terminals with bottom mounting. It has a continuous current rating of 50 A and a voltage rating of 750 V DC, with SPST-NO contacts and M5 silver-plated copper terminals. The device is sealed to IP67, operates from -40 to 85°C, and measures 46 mm × 58 mm × 41 mm. Mounting is with M4 bolts at 2.3 Nm torque, and contact torque is 3.4-4.5 Nm. It is UL recognized (File No. E510407) and manufactured under IATF16949. Auxiliary contacts are not included in this variant.
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.
