Sensata Gigavac GX16CE DC Contactor

The Sensata Gigavac GX16CE is a sealed hermetic DC contactor from the GX16 Series, designed for high-current DC switching in power systems up to 800VDC. It provides a 600A contact rating, 24VDC coil operation, chassis mounting, connector and stud termination, and SPST-NO main contact configuration. This model is suitable for electric vehicles, battery energy storage systems, industrial DC power distribution, marine power control, solar equipment, power management 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 GX16CE DC contactor is designed for reliable high-current switching in demanding DC power systems. As part of the GX16 Series, this model supports a 600A contact current rating and up to 800VDC maximum switching voltage. It is commonly used in EV battery systems, energy storage equipment, power management systems, industrial DC cabinets, marine electrical systems, solar power equipment, and battery disconnect applications.

The GX16CE 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 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 GX16CE is its hermetically sealed construction. The sealed contact chamber helps protect the internal contact system from dust, moisture, oxidation, and contaminated environments. This makes the GX16CE suitable for harsh operating conditions, including mobile equipment, outdoor systems, battery packs, and industrial power assemblies where open-frame contactors may have reduced service life.

The GX16 Series is designed for long-term switching performance and high-current DC power control. The GX16CE uses chassis mounting with connector and stud termination, giving engineers a secure installation method for high-current bus or cable connections while keeping coil/control wiring organized through a connector interface. Its fast 20 ms operate time and 7 ms release time support responsive control in battery disconnect, charge, load, and safety isolation circuits.

Applications

The GX16CE DC contactor is suitable for systems that need reliable connection and disconnection of high-current DC battery, load, or charging circuits. Typical applications include electric vehicles, battery energy storage systems, solar power equipment, DC power cabinets, marine battery systems, UPS battery modules, material handling equipment, and industrial automation systems.

In a battery system, the Sensata Gigavac GX16CE can be used as a main contactor, charge contactor, load disconnect contactor, or safety isolation device depending on the electrical design. Its 600A current rating makes it a strong fit for high-current DC platforms where sealed construction, compact mounting, and stable switching performance are required.

Why Choose Sensata Gigavac GX16CE

The Sensata Gigavac GX16CE is a strong option when the system requires 600A current capacity, up to 800VDC switching voltage, 24VDC coil operation, sealed construction, chassis mounting, and connector with stud termination. Compared with lower-current contactors, this model is better suited for demanding battery and DC bus applications. Compared with open-frame contactors, the sealed hermetic structure helps improve reliability in vibration, moisture, and contamination-prone environments.

For replacement and maintenance projects, GX16CE should be selected when the original system requires GX16 Series performance with 600A contact rating, 800VDC maximum switching voltage, 24VDC coil voltage, chassis mounting, connector control termination, and stud power terminals. Before ordering, confirm coil voltage, load current, switching voltage, mounting space, terminal style, and control circuit requirements.
