Product Description
Gigavac GH3 3.5kV SPDT HV Relay
Gigavac GH3 SPDT High Voltage Relay - 3.5kV / 18A
The **Gigavac GH3** is a compact, vacuum-sealed Single Pole Double Throw (SPDT) high-voltage relay designed for high-speed switching and reliable power management. Engineered to handle peak voltages up to **3.5kV** and a continuous carry current of **18 Amps**, the GH3 stands out with its ultra-fast **6ms** operate and release times. Its hermetically sealed vacuum dielectric ensures low (0.02 Ohms) and stable contact resistance over a mechanical life of **2 million cycles**. This makes the GH3 an ideal solution for applications where space is limited but fast response and long-term durability are critical.
