The DCNLEV50-BN is a high-current, high-voltage DC contactor relay designed for electric vehicle and industrial applications, featuring a bottom mount, non-polarized load terminals, and a 12 V DC nominal coil voltage operating between 8 and 16 V DC. It has a continuous current rating of 50 A and a voltage rating of 750 V DC, with SPST-NO contact configuration. The relay is sealed to IP67, uses nylon UL 94-V0 housing, and incorporates a gas-filled chamber to mitigate arcing. Physical dimensions are 46 mm × 58 mm × 41 mm, with M5 silver-plated copper terminals and M4 mounting bolts requiring 2.3 N·m torque. It operates from -40 to 85 °C and meets UL File No. E510407 recognition. Weight is 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-BN) features a 12 V coil and non-polarized contacts. In addition, the 50 A relay has a bottom mounting style.
