GX Series — Hermetically Sealed DC Contactors800 Vdc Patented Technology
The GIGAVAC GX series is a field-proven, patented ceramic-insulated hermetic flagship DC contactor family in service since 2002. 26 models deliver 150-1000 A continuous current and switching from 12 to 800 Vdc.
RoHS compliant and mountable in any orientation, GX operates from -55 °C to 85 °C and runs reliably in harsh environments including underwater; cRUus certified.
Beyond standard NO models, the family includes latching, current-sensing, CAN-bus (GXC) and PWM-coil variants — chosen for EV power management, ESS, industrial control and pre-charge circuits.

26 models cover virtually any panel architecture.
Mount in any desired orientation
Flexible panel design, fast install, optimised footprint.
Built-in Coil Suppression
Internal coil suppression on every DC-coil variant
No external diode/snubber needed — shorter install time, lower BOM.
Stainless-steel hardware and mounting inserts
Years of corrosion-free service — ideal for marine and humid environments.
Smart Variant Portfolio
Latching (GXL), current sensing (GXSA), CAN-bus (GXC), PWM coil (GXV)
BMS integration, current protection and digital comms — all from one family.
NO (Normally Open) and NC (Normally Closed) options
Safe break or make architecture, depending on circuit topology.
