The DCNLEV50-CASN is a high-current, high-voltage DC contactor relay designed for electric vehicle and industrial applications, featuring a 24 V DC nominal coil (16-28 V DC working), non-polarized load terminals, side mounting, and an auxiliary SPST-NO contacts circuit rated for 2 A at 30 V DC or 3 A at 125 V AC. It has a continuous carry current of 50 A, a voltage rating of 750 V, IP67 ingress protection, and operates from -40 to 85 °C. The device is sealed and gas-filled to mitigate arcing, with a compact housing of 46 mm × 58 mm × 41 mm, secured with M4 mounting bolts at 2.3 Nm torque. Contacts use M5 silver-plated copper terminals with a contact torque of 3.4-4.5 Nm. It is UL Recognized (File No. E510407) and manufactured under IATF16949 certification.
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-CASN) features a 24 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.
