DCNEVT400-B - DCNEVT400 Series

Roll Over to Zoom

High current and high voltage DC contactor relays for electric vehicle, hybrid electric vehicle, circuit protection, battery switch, and main power break. The Coil Economizer greatly reduces coil 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. Utilizes polarized contacts for optimum performance amidst polarized electrical loads.
