Heavy-duty AC and DC contactors

October 2018 Electrical Power & Protection

Gigavac’s MX Series extended performance impervious ceramic (EPIC) sealed AC and DC contactors are designed to meet MIL-R-6106 and are especially suited for military vehicles and heavy duty applications. The hermetically sealed chamber ensures that coil, contacts and electronics are shielded from all outside environmental factors. The ceramic to metal weld allows for operation in extreme temperatures up to 200°C. Silver contacts ensure long life and contact weld resistant operation, even in high inrush and overload applications. The dual coil design allows for low power coil operation without the use of EMI generating PWMs.

Options with NO, NC and latching contactors are available, as well as versions with integrated current and/or voltage sensing abilities. Other features include:

• Continuous carry current up to 1000 A.

• Coil voltages 12, 24 and 48 V DC.

• Auto over-current disconnect.

• Current sensing.

• Time delay on break.

• Auto low voltage disconnect.
