JPK-3/002 SPST-NC Vacuum Relay Switch High Voltage DC40KV Carry 14A Current good for capacitor discharging to Ground.


Since the vacuum relay uses a vacuum medium, it has the following excellent performance.

1 Vacuum relay is a relay that places the contacts in ceramic shell that is pumped into a high vacuum, using vacuum as an arc extinguishing and insulating medium.
2 Vacuum has ideal insulation performance. Under ideal conditions, it may reach a dielectric constant of 80,000 V/mm. Since there is no oxygen in the vacuum, it will not oxidize during use. Thus, the vacuum relay has a small amount during use. Stable contact resistance.
