The DCNEVT500-B is a 500A continuous, 1800V DC single-pole normally open contactor designed for electric vehicle and industrial applications. It features a hermetically sealed contact chamber, dual coil economizer with PWM to reduce holding power, and polarized M10 silver-plated copper terminals. The part has a 12V DC nominal coil voltage (9.9-14V DC operating range), a 3.3A max coil inrush current, and operates from -40°C to 85°C. It is mounted with M5 bolts at 3-4 Nm torque, measures 74mm x 54mm x 120mm, and is rated IP54. The contactor 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-B) has a 12V coil rating. High-current (500A) and high-voltage (1800V) DC contactor for electric vehicles (EV) and eMobility applications 12V dc (nominal), 9.9-14V dc (working) coil voltage rating
