The DCNEVT500-C is a high-current, high-voltage DC contactor relay rated for 500A continuous carry and 1800V DC, designed for electric vehicle, battery switch, and main transfer applications. It features a SPST-NO contact arrangement, hermetically sealed contact chamber, and a dual coil economizer that reduces power consumption after activation via PWM. The coil is rated for 24V DC nominal with a working range of 19.7 to 28V DC, and has an inrush current of 1.7A. The device has an IP54 ingress protection rating, operates from -40 to 85°C, and is mounted via M5 bolts with a torque of 3-4 Nm. Its dimensions are 74mm x 54mm x 120mm, with M10 silver-plated copper terminals and a weight of 1.53 kg. It meets UL File No. E510407 and is manufactured under IATF16949.
Thanks, in part, to a hermetically sealed, ceramic arc chamber, the DCNEVT500 1800V 500A High-Voltage DC Contactor Relay is an ideal choice for electric vehicle (EV), hybrid electric vehicle (HEV), circuit protection, battery switch disconnect, and main transfer switch applications.The high-voltage, single-pole contactor also features a dual coil economizer that reduces power and heating after the contactor is energized. Once the contactor is energized, it takes minimal coil power to keep the contacts closed due to pulse width modulation (PWM) reducing the average power delivered by pulsing the electrical signal.Utilizing polarized contacts, this high-voltage DC contactor performs optimally amidst polarized electrical loads.This configuration of the DCNEVT500 Series electric vehicle contactor (DCNEVT500-C) has a 24V coil rating.
