Sensata Gigavac GX14CC DC Contactor

The Sensata Gigavac GX14CC is a sealed hermetic DC contactor from the GX14 Series, designed for 350A current switching in power systems up to 800VDC. It uses a 24VDC internal coil, chassis mounting, stud and wire lead termination, 122 cm / 48 in flying leads, and no auxiliary contact. This model is suitable for electric vehicles, hybrid vehicles, battery energy storage systems, heavy trucks, emergency vehicles, industrial DC power distribution, marine power control, and OEM battery disconnect modules. In this model, 800VDC refers to the main contact switching voltage, while 24VDC refers to the coil voltage used to operate the contactor.

Product Description

The Sensata Gigavac GX14CC DC contactor is designed for reliable high-voltage DC switching in battery and power control systems. As part of the GX14 Series, this model provides a 350A contact current rating and up to 800VDC maximum switching voltage. It is commonly selected for electric vehicles, hybrid vehicles, battery energy storage systems, heavy trucks, emergency vehicles, industrial DC cabinets, battery charging systems, and OEM battery disconnect assemblies.

The GX14CC uses an SPST-NO main contact arrangement, also described as 1 Form X. The main power contact remains open when the coil is not energized and closes when the 24VDC coil receives the correct control signal. This allows a low-voltage control circuit to manage a higher-voltage DC load path. The 800VDC value belongs to the main switching circuit, while the 24VDC value belongs only to the coil control circuit.

A key advantage of the Sensata Gigavac GX14CC is its sealed EPIC construction. The hermetically sealed design helps protect the internal contact system from dust, humidity, oxidation, and contamination. The GX14 platform is designed for harsh environments and can be used in demanding applications where vibration, moisture, and thermal stress may reduce the service life of ordinary open-frame contactors.

This model uses stud and wire lead termination with 122 cm / 48 in flying leads. The longer lead configuration is useful in battery boxes, power distribution modules, EV control cabinets, and industrial assemblies where the coil circuit must be routed to a controller or harness connection point. Since GX14CC has no auxiliary contact, it is best suited for systems where separate contactor feedback is not required.

Applications

The GX14CC DC contactor is suitable for systems that need reliable connection and disconnection of DC battery, load, or charging circuits. Typical applications include electric vehicles, hybrid vehicles, heavy trucks, emergency vehicles, battery energy storage systems, battery charging equipment, marine battery systems, UPS battery modules, material handling equipment, and industrial automation systems.

In a battery system, the Sensata Gigavac GX14CC can be used as a main contactor, charge contactor, load disconnect contactor, or safety isolation device depending on the electrical design. Its 350A current rating makes it a strong fit for medium-to-high current DC platforms where sealed construction and stable switching performance are required.

Why Choose Sensata Gigavac GX14CC

The Sensata Gigavac GX14CC is a strong option when the system requires 350A current capacity, up to 800VDC switching voltage, 24VDC coil operation, sealed construction, 48 in wire leads, and no auxiliary contact. Compared with versions that include auxiliary feedback, this model is simpler for designs where the controller does not need a separate auxiliary signal.

For replacement and maintenance projects, GX14CC should be selected when the original system requires GX14 Series performance with 350A contact rating, 800VDC maximum switching voltage, 24VDC coil voltage, chassis or busbar mounting, stud and wire lead termination, and no auxiliary contact. Before ordering, confirm coil voltage, auxiliary contact requirement, load current, switching voltage, mounting space, and terminal requirements.
