Product Description
Gigavac G81C345 HV Relay
Gigavac G81C345 SPDT High Voltage Relay - 10kV / 10A
The Gigavac G81C345 is a high-performance Single Pole Double Throw (SPDT) high-voltage relay, precision-engineered for superior isolation and reliable switching in demanding power systems. Capable of handling peak voltages up to 10kV and offering carry currents up to 10 Amps, this vacuum-sealed relay ensures exceptionally low (0.05 Ohms) and stable contact resistance. With its rapid 10ms operate and release times and an impressive mechanical life of 2 million cycles, the G81C345 is an essential component for high-voltage power supplies, RF communication, and medical electronics where safety and long-term durability are critical.
