Product Description
Gigavac G20WP 28kV SPST-NO HV Relay
Gigavac G20 SPST-NO High Voltage Relay - 28kV / 110A
The **Gigavac G20** is a heavy-duty Single Pole Single Throw (SPST) normally open high-voltage relay, engineered for applications requiring massive current carry capacity and high-voltage isolation. Capable of handling peak voltages up to **28kV** and a remarkable continuous carry current of **110 Amps**, the G20 features **Tungsten contacts** to ensure an extended operational life even under rigorous switching cycles. Its vacuum dielectric construction is optimized for high-inrush currents and effective load switching, while the inert gas dielectric maintains low and stable contact resistance. With threaded high-voltage connections for easy and secure installation, the G20 series is a premier solution for industrial power supplies and advanced high-power systems.
