GIGAVAC's GX Series EPIC® (Extended Performance Impervious Ceramic) sealed DC Contactors contactors switch both low and high voltage from 12 to 750, both DC and AC. These small RoHS compliant hermetically sealed contactors can be mounted in any position, can be used in nearly any harsh environment including under water and at temperatures from –55°C to 85°C. They are the preferred contactor (they are also sometimes called a relay or solenoid) for heavy trucks and equipment, busses, emergency vehicles, electric vehicles, hybrid vehicles, boats, light rail, mining, oil and factory automation,  power management systems for battery charging,  fuel cells, battery backup, solar, wind and wave power systems where long life and high reliability are needed. Most are cruus recognized.



Gigavac 350A 750VDC GX14 Relay / Contactor


  • Contact configuration: SPST-NO
  • Temperature rating: -55 to +85 Degrees Celcius
  • RoHs compliant


This contactor is rated at 350 amps continuous (see "Important Note" below) at voltages up to 750VDC! It is available with a 12VDC coil (24VDC, or 48VDC can also be supplied), and comes with magnetic blowouts. It's sealed and has terminals that are easy to connect to. The coil has a unique economizer design that briefly draws a higher current to pull in the contacts, then settles at a much lower current to reduce power consumption.

Important note: It's recommended to use the largest feasible cable diameter to keep temperature rise on the contacts as low as possible. The 350A rating is obtained using 400 KCmil cable (approximately 7/0 cable!). Using smaller diameter cable WILL REDUCE the continuous current rating.

For more detailed information on the device, see the Gigavac website on the GX14. Options listed by Gigavac that aren't offered below can be special ordered. Contact us for details.
