Product Description
Gigavac GH1 3.5kV SPDT HV Relay
Gigavac GH1 SPDT High Voltage Relay - 3.5kV / 25A
The Gigavac GH1 is a compact, high-reliability Single Pole Double Throw (SPDT) vacuum relay designed for precision switching in high-voltage environments. Engineered to handle peak voltages up to 3.5kV and a continuous carry current of 25 Amps, the GH1 stands out with its ultra-fast 6ms operate and release times. Its vacuum-sealed design ensures an exceptionally low (0.01 Ohms) and stable contact resistance over a mechanical life of 2 million cycles. This makes the GH1 an ideal solution for applications where fast response, high current handling, and long-term durability are critical.
