The DCNEVT500-CA is a high-current, high-voltage DC contactor relay rated for 500A continuous carry and 1800VDC, designed for electric vehicle and eMobility applications such as battery switch disconnect and main transfer switch. It features a hermetically sealed contact chamber, polarized contacts, and a dual coil economizer that reduces power consumption after energization via PWM. The device has a 24V DC nominal coil voltage (19.7-28V DC working range), an auxiliary SPST-NO contact rated for 10W and 100VDC, and an insulation class compliant with UL File No. E510407. It is housed in a nylon UL 94-V0 enclosure with IP54 protection, operates from -40 to 85°C, and measures 74mm x 54mm x 120mm with M5 mounting bolts requiring 3-4 Nm torque. Terminals are M10 silver-plated copper, and compliance with IATF16949 is specified for automotive quality systems.
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-CA) has a 24V coil rating and an auxiliary contact. High-current (500A) and high-voltage (1800V) DC contactor for electric vehicles (EV) and eMobility applications 24V dc (nominal), 19.7-28V dc (working) coil voltage rating Includes auxiliary contact rated for 2A at 30V dc and 3A at 125V dc
