HV Relay JPK-20A SPST-NO Vacuum Relay Switch High Voltage DC28KV Carry 110A Current




Vacuum Relay 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.


high electric strength, rated carrying current and conversion current, small contact resistance, stable operation, low noise, small distributed capacitance and inductance between poles, small contact opening distance, low excitation power and fast breaking speed. The contact seal is not affected by the pressure, moisture, dust or explosive gas in the surrounding environment, and is suitable for working in harsh environments.
