Sensata Gigavac GX110CE DC Contactor

The Sensata Gigavac GX110CE is a sealed hermetic DC contactor from the GX110 Series, designed for very high-current switching in power systems up to 800VDC. It provides a 1000A contact rating, 24VDC coil operation, chassis mounting, connector and stud termination, and no auxiliary contact. This model is suitable for electric vehicles, battery energy storage systems, heavy-duty DC power distribution, marine power control, industrial battery systems, mining equipment, rail systems, 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 GX110CE DC contactor is designed for reliable very high-current switching in demanding battery and DC power systems. As part of the GX110 Series, this model supports a 1000A contact current rating and up to 800VDC maximum switching voltage. It is commonly used in electric vehicles, energy storage systems, heavy-duty industrial equipment, marine power systems, mining equipment, rail power systems, UPS battery cabinets, and large battery disconnect assemblies.

The GX110CE uses an SPST-NO main contact arrangement, also described as 1 Form X. The main contact remains open when the coil is not energized and closes when the 24VDC coil receives the correct control voltage. This allows a low-voltage control circuit to manage a very high-current DC power 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 GX110CE is its rugged hermetically sealed EPIC construction. The sealed contact chamber helps protect the internal contact system from dust, moisture, oxidation, and contamination. Sensata describes the GX110 platform as using an EPIC seal rated to 175°C, designed to reduce risk in over-current conditions and support harsh applications where open-frame contactors may not provide enough environmental protection.

This model uses connector and stud termination. The stud terminals support secure high-current power connections, while the connector interface helps organize coil wiring. Since GX110CE does not include an auxiliary contact, it is best suited for systems where separate contact feedback is not required or where contactor status is monitored through another circuit.

Applications

The GX110CE DC contactor is suitable for systems that need reliable connection and disconnection of very high-current DC battery, load, or charging circuits. Typical applications include electric vehicles, battery energy storage systems, DC power distribution cabinets, marine battery systems, UPS battery modules, rail equipment, mining vehicles, heavy-duty industrial equipment, and large battery disconnect systems.

In a battery system, the Sensata Gigavac GX110CE can be used as a main positive contactor, main negative contactor, charge path contactor, load disconnect contactor, or safety isolation device depending on the electrical design. Its 1000A current rating and 800VDC switching capability make it suitable for high-current platforms where sealed construction, compact control wiring, and stable switching performance are required.

Why Choose Sensata Gigavac GX110CE

The Sensata Gigavac GX110CE is a strong option when the system requires 1000A current capacity, up to 800VDC switching voltage, 24VDC coil operation, sealed construction, connector and stud termination, and no auxiliary contact. Compared with lower-current contactors, this model is better suited for heavy-duty battery and DC bus applications. Compared with auxiliary-contact versions, GX110CE is simpler for systems where feedback is handled elsewhere.

For replacement and maintenance projects, GX110CE should be selected when the original system requires GX110 Series performance with 1000A contact rating, 800VDC maximum switching voltage, 24VDC coil voltage, chassis mounting, connector/stud termination, and no auxiliary contact. Before ordering, confirm coil voltage, auxiliary contact requirement, load current, switching voltage, mounting space, and terminal requirements.
