The DCNLEV50-BAS is a high-current, high-voltage DC contactor relay designed for electric vehicle and industrial applications, featuring a side mount, 12 V DC nominal coil with 8-16 V DC operating range, polarized load terminals, and an auxiliary SPST-NO contact circuit rated for 2 A at 30 V DC or 3 A at 125 V AC. It has a continuous current rating of 50 A, a voltage rating of 750 V DC, and an IP67 sealed, gas-filled enclosure. The housing is nylon UL 94-V0, terminals are M5 silver-plated copper, and dimensions are 46 mm × 58 mm × 41 mm. It operates from -40 °C to 85 °C, meets UL E510407 recognition, and is manufactured under IATF16949. Mounting torque is 2.3 Nm, and contact torque is 3.4-4.5 Nm.
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-BAS) features a 12 V coil and polarized contacts. In addition, the 50 A relay has a side mounting style and a single-pole, single-throw (SPST), normally open (NO) auxiliary circuit.
