EG Electronics | Ebusbar EVC Serie High Voltage DC Relay

Description

The high-voltage DC relay EVC-serie adopts a ceramic sealing structure, which can cut off the load voltage of up to 1000VDC. The high-voltage DC relay EVC-serie can maintain stable contact resistance regardless of the environment.

With ceramic seal structure, the contact chamber filled with hydrogen mixed reducing gas, combined with magnetic blow-out.

Voltage relay can cut off load voltage of 1000VDC.
Compact Design & Low Operating Sound

By using a capsule contact mechanism that is enclosed with hydrogen gas, highcapacity cutoff is possible even with a tiny contact gap. There is little operating sound, which does not change even when large currents are cut off.

The enclosure box is smaller thanks to an arc-space-free construction from which the arc will not get out. Arc will not get out with design of that contacts are enclosed in a sealed capsule.

The contact part is hermetically sealed with H2 mixed gas, hence the contact resistance remains stable regardless of the ambient conditions.
