Littelfuse, Inc. 1800V 500A High-Voltage DC Contactor Relay DCNEVT500-CA

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.Features and BenefitsHigh-current (500A) and high-voltage (1800V) DC contactor for electric vehicles (EV) and eMobility applications24V dc (nominal), 19.7-28V dc (working) coil voltage ratingIncludes auxiliary contact rated for 2A at 30V dc and 3A at 125V dc
