The DCNEVT350-BA is a high-current, high-voltage DC contactor relay designed for electric vehicle and eMobility applications, featuring a 350A continuous current rating and 1800VDC voltage rating. It includes an auxiliary SPST-NO contact and is equipped with a sealed control wire connector. The device uses a coil economizer with PWM to reduce holding power after energization, and features polarized contacts for optimal performance with polarized loads. The contactor has an IP54 ingress protection rating, operates from -40°C to 85°C, and is mounted via M6 bolts with a torque of 1.7-3.3 Nm. Terminals are silver-plated copper M6 with a contact torque of 6-8 Nm. The auxiliary contact is rated for 10W and 100VDC, with a maximum resistance of 500mΩ. The unit is UL recognized under File No. E510407 and manufactured under IATF16949 certification. The housing is Nylon UL 94-V0. Weight is 0.8 kg.
Ideal for electric vehicle (EV), hybrid electric vehicle (HEV), circuit protection, battery switch, and main power break applications, the DCNEVT350 Series 1800V 350A High-Voltage DC Contactor Relay features a ceramic arc chamber, which allows higher contact voltage capability. The hermetically sealed contact chamber also protects all moving parts, allowing the EV contactor to be used in harsh automotive environments.The automotive relay is designed with 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.Polarized contacts enable the high-voltage DC contactor to perform optimally amidst polarized electrical loads.This model of the DCNEVT350 Series contactor for electric vehicles (DCNEVT350-BA) comes with a sealed wire control connector and features a 12V dc coil voltage rating and an auxiliary circuit. High-current (350A) 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
