Features of product:

Great temperature resistance property, can work under condition from -55℃ to 85℃.
Adopts ceramic, the same with the space program; reduced risk of fire or meltdown in over-current conditions.
Small size, can withstand and switch large current.
Hermetically sealed, with no risks of arcing leakage and fire.
Sealing chamber can effectively prevent contact oxidized and melted. Low and stable contact resistance.
Can be used in any environment, including immersion, high/low pressure and other harsh environment.
Not position sensitive, can be mounted in any position for ease of installation.

Applications:

This high voltage DC contactor adopts advanced extended performance impervious ceramic sealing technology, which takes the place of common glass or epoxy sealing technology. Products with ceramic sealing technology have higher usage temp and more reliable sealing performance.
Such contactor has the advantage of small volume, long life and light weight.
Functions are similar with that of EV DC contactor produced by Kilovac and Panasonic.
Widely used in AD or DC power supply switch of mining – drive and control system, electric vehicle, mobile mining equipment, aviation mobile devices, backup power supply system, hydrogen fuel cell drive system, ships and underwater equipment, solar power equipment. It is the ideal choice of large mobile power supply circuit.
