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.
Available configurations of this bottom-mount 500A contactor for electric vehicles include models with 12V dc or 24V dc coil voltage ratings and models with or without an auxiliary contact.
- High-current (500A) and high-voltage (1800V) DC contactor for electric vehicles (EV) and eMobility applications
