Sensata Gigavac GX14CC

Sensata Gigavac GX14CC is a GX14 series High Voltage DC Contactor designed for compact 800VDC-class battery disconnect and DC power control systems. This High Voltage DC Contactor provides a 350A current rating, 24VDC coil control, SPST-NO double-make contact form, chassis mounting, stud power terminals, wire leads, and hermetically sealed construction. For OEMs building battery packs, compact inverter modules, service disconnect boxes, and mobile energy systems, the GX14CC High Voltage DC Contactor offers a balanced combination of size, current capability, and sealed switching performance.

The GX14CC High Voltage DC Contactor is a normally open model, which means the main contact path remains open until the coil is energized. This behavior is commonly preferred for battery disconnects, charger interfaces, service isolation circuits, and controlled startup sequences. In a compact enclosure, the High Voltage DC Contactor can be placed near the battery output, inverter input, or protected load branch to provide a clear controlled switching point.

Product Positioning

GX14CC is positioned as a compact battery disconnect High Voltage DC Contactor for 24V control systems. It is smaller in application scope than 600A GX16, GX46, or GX66 models, but it provides more power switching capability than light-duty control relays. This High Voltage DC Contactor is a practical fit for equipment where 350A current rating is enough and space efficiency is important.

The 24VDC coil is a major reason to select the GX14CC High Voltage DC Contactor. Many industrial panels, battery management systems, and vehicle control circuits use a 24V auxiliary supply. Using a 24V coil High Voltage DC Contactor allows the designer to integrate the contactor into existing control hardware without adding another coil power rail. The wire lead termination also gives flexibility for routing control wiring inside compact cabinets.

Features and Benefits

The first benefit of GX14CC is compact sealed switching. A High Voltage DC Contactor in the 350A class can serve many battery and inverter systems without using a larger 600A package. This helps engineers save space in battery boxes, mobile power modules, and service disconnect panels. The sealed GX design also helps protect the High Voltage DC Contactor from dust, moisture, and contamination.

The second benefit is straightforward 24V control. A 24VDC coil High Voltage DC Contactor is compatible with many BMS outputs, industrial controllers, and charger control boards. That compatibility can simplify wiring and reduce auxiliary hardware. In production equipment, a consistent 24V control platform can also make assembly and troubleshooting easier.

The third benefit is practical termination. Stud power terminals provide a strong current path for cable lugs, while wire leads provide routing flexibility for the coil connection. This makes the GX14CC High Voltage DC Contactor useful in compact layouts where a connector may not be ideal or where the harness must be routed around other power components.

Because GX14CC is a normally open High Voltage DC Contactor, it supports controlled energizing of the DC bus. The contactor can remain open during service, transport, or fault response, then close only when commanded by the control system. This behavior is valuable in battery packs, charger outputs, DC distribution branches, and inverter startup circuits.

Applications

GX14CC is a strong High Voltage DC Contactor choice for compact battery disconnect systems. It can be used between a battery pack and inverter, between a charger and battery input, or between a DC source and protected load. In these designs, the High Voltage DC Contactor acts as the main controlled switching point for a 350A class power path.

In mobile equipment, the GX14CC High Voltage DC Contactor can support battery isolation for utility vehicles, compact electric machinery, service carts, and mobile energy modules. In stationary systems, this High Voltage DC Contactor can be installed in DC distribution panels, battery backup cabinets, renewable energy support boxes, and inverter interface assemblies.

Additional applications include charger output switching, battery test equipment, compact DC UPS modules, power conversion prototypes, and service disconnect units. The High Voltage DC Contactor should be selected with attention to current rating, maximum voltage, coil voltage, duty cycle, inrush current, and protection coordination.

Selection Guide

Select GX14CC when the design requires a 350A High Voltage DC Contactor for an 800VDC-class circuit with 24VDC coil control. If the system requires normally closed behavior, GXNC14CB may be a better match. If the application needs 600A current capacity, a GX16 or larger High Voltage DC Contactor should be reviewed.

Before replacing another contactor with this High Voltage DC Contactor, verify terminal spacing, cable lug size, mounting clearance, coil drive capacity, operating temperature, precharge requirements, and whether auxiliary feedback is needed. GX14CC is a clean normally open High Voltage DC Contactor option, but the full circuit must still be reviewed for safe operation.
