The DCNEVT400-BA is a high-current, high-voltage DC contactor relay designed for electric vehicle, hybrid electric vehicle, battery switch, and main power break applications. It features a single-pole, single-throw normally open (SPST-NO) contact arrangement with a hermetically sealed contact chamber and a coil economizer that reduces power consumption via pulse width modulation after energization. The device has a 400A continuous current rating and is rated for 1800V DC. It includes an auxiliary SPST-NO contact rated for 100V DC and 10W, along with a sealed wire connector. The contactor is mounted via M6 bolts with a torque of 1.7-3.3 Nm and uses silver-plated copper M6 terminals. It operates from -40°C to 85°C, complies with IP54 ingress protection, and is manufactured under IATF16949. The coil voltage is 12V DC nominal (9-16V DC working), with a maximum inrush current of 2.8A and a holding current of 0.40A. Weight is 1.76 lb (0.8 kg).
Featuring a ceramic arc chamber that enables a high contact voltage capability, the DCNEVT400 Series 1800V 400A High-Voltage DC Contactor Relay is designed for electric vehicle (EV), hybrid electric vehicle (HEV), circuit protection, battery switch, and main power break applications. The contact chamber of this single-pole, single-throw (SPST), normally open (NO) contactor is hermetically sealed to protect all moving parts.The DCNEVT400 Series electric vehicle contactor also features a coil economizer that 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.This automotive relay has polarized contacts, so it performs optimally amidst polarized electrical loads.This model of the DCNEVT400 Series EV contactor (DCNEVT400-BA) comes with a sealed wire control connector with 7" leads and features a 12V dc coil voltage rating and an auxiliary circuit. High-current (400A) and high-voltage (1800V) DC contactor for electric vehicles (EV) and eMobility applications 12V dc (nominal), 9-16V dc (working) coil voltage rating Includes auxiliary contact rated for 2A at 30V dc and 3A at 125V dc
