The DCNLEV50-BASN is a high-current, high-voltage DC contactor relay designed for electric vehicle and industrial applications, featuring a side-mount configuration, non-polarized load terminals, and an auxiliary SPST-NO circuit. It has a 50 A continuous current rating and 750 V DC voltage rating, with a 12 V DC nominal coil (8-16 V DC operating range). The relay is sealed to IP67, uses a gas-filled contact chamber to mitigate arcing, and operates within a temperature range of -40 to 85°C. It is mounted using M4 bolts with a torque of 2.3 Nm and has M5 silver-plated copper terminals with a contact torque of 3.4-4.5 Nm. The device is UL recognized (File No. E510407) and manufactured under IATF16949 certification. Its physical size is 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-BASN) features a 12 V coil and non-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.
