Sensata Gigavac GX110CE

Sensata Gigavac GX110CE is a 1000A 800VDC High Voltage DC Contactor from the GX110 EPIC series, built for grid battery containers, utility-scale DC cabinets, large inverter rooms, and high-current energy infrastructure. This High Voltage DC Contactor uses an SPST-NO-DM main contact form, a 24VDC internal coil, stud power terminals, an 8-pin connector interface, chassis or flange mounting, and hermetically sealed EPIC construction. It is intended for systems where very high current switching, organized connector wiring, and sealed contactor reliability are more important than auxiliary feedback wiring.

GX110CE is best used in large stationary power assemblies where the contactor becomes part of the main DC path. A grid battery container or industrial energy skid may need to connect a battery rack to a PCS input, isolate a DC bus segment, switch a high-current charge path, or open a protected distribution section during maintenance. The 1000A current class gives this High Voltage DC Contactor a role that is clearly different from 350A, 500A, or 600A contactor families.

Product Positioning

GX110CE should be positioned as a 24V coil High Voltage DC Contactor for grid battery containers and stationary high-current DC infrastructure. Compared with GX110BEB, which uses a 12VDC coil, GX110CE is better matched to equipment that standardizes on 24VDC cabinet control power. Compared with GX16CE or GX16CEB, GX110CE provides a higher 1000A current rating for heavier DC bus sections.

This model is also different from HX 1500VDC contactors. GX110CE focuses on very high current in 12-800VDC systems, while HX models are selected when the voltage class needs to reach 1500VDC. For cabinet builders working in 800VDC-class energy storage and industrial DC distribution, GX110CE provides a strong high-current option with a connectorized control interface.

Features and Benefits

The main advantage of GX110CE is its 1000A current capability. A High Voltage DC Contactor in this class can handle main DC bus switching, rack aggregation paths, inverter DC inputs, high-current charger outputs, and large battery isolation circuits where smaller devices would be undersized.

The 24VDC internal coil fits common stationary cabinet control systems. Energy storage containers, industrial power cabinets, and large DC distribution skids often use 24VDC for PLCs, sensors, fans, relays, contactors, and safety circuits. Selecting GX110CE helps align the contactor with that existing auxiliary power architecture.

The 8-pin connector improves control-side organization. Connectorized wiring can help reduce assembly variation, simplify service replacement, and keep the low-voltage harness cleaner than loose-lead wiring. This is useful in containerized systems where repeatable builds and field maintenance both matter.

Stud terminals provide robust connection points for large cables or busbars. At 1000A, conductor sizing, torque control, thermal rise, busbar layout, and fuse coordination are critical. GX110CE gives designers a contactor format intended for serious high-current DC power paths.

The EPIC hermetically sealed construction helps protect the contact system from dust, humidity, and contaminated air. A sealed High Voltage DC Contactor is valuable in utility containers, industrial rooms, and mobile power skids where long service intervals and reliable switching behavior are required.

Applications

GX110CE is especially suitable for grid battery containers and utility-scale energy storage equipment. In a containerized battery system, this High Voltage DC Contactor can connect a rack group, isolate a PCS input, switch a high-current charge path, or disconnect a DC bus section during service and fault events.

The contactor can also be used in industrial DC distribution, large backup power systems, heavy charger cabinets, mobile energy skids, marine battery rooms, and high-current inverter assemblies. Its 1000A rating makes it appropriate for demanding current paths where 500A or 600A models may not provide enough margin.

Selection Guide

Before selecting GX110CE, confirm maximum DC voltage, continuous current, peak current, inrush current, switching duty, and fault-clearing strategy. This High Voltage DC Contactor is intended for 1000A-class 800VDC systems, but final suitability depends on busbar sizing, cable routing, thermal rise, precharge design, fuse coordination, and enclosure conditions.

The coil supply should be a stable 24VDC source. Designers should verify the 8-pin connector pinout, coil driver capacity, terminal clearance, mounting orientation, vibration exposure, and service access. If auxiliary feedback is required, confirm the exact GX110 variant before ordering. If the system uses 12VDC control power, GX110BEB or another 12V coil model may be more appropriate.
