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.
