Dongya’s high voltage DC Contactor are typically fitted with a normally open (NO) contact and Ev Dc Contactor suppress the arc that is produced when interrupting heavy motor currents. Ev Dc Contactor are designed to meet the demands of high-voltage and high-current DC applications, especially for disconnecting high-voltage lithium-ion batteries. The HV contactors can handle currents up to 1000A@1500VDC with the hermetically sealed and gas-filled ceramic arc chamber by gas tube technology. 
The HVC series can be used in a wide range of applications where fast and reliable disconnection of high DC voltages is required.
