Sensata Gigavac GX14CCB

Sensata Gigavac GX14CCB is a 350A 800VDC High Voltage DC Contactor designed for mobile equipment, emergency vehicles, utility platforms, industrial battery systems, and rugged DC power switching. This GX14 series High Voltage DC Contactor uses a 24VDC coil, SPST-NO main contact arrangement, auxiliary contacts, stud power terminals, wire leads, and hermetically sealed construction. The GX14CCB High Voltage DC Contactor is especially useful when a vehicle or machine builder needs a compact 24V-controlled contactor that can carry high DC current in a harsh operating environment.

This page positions GX14CCB around mobile-equipment DC isolation rather than generic energy storage copy. In mobile machines, a High Voltage DC Contactor must handle vibration, temperature change, service cycles, and electrical noise while remaining easy to install inside a battery box or DC control enclosure. GX14CCB supports that use case with sealed construction, auxiliary feedback, and practical stud-terminal wiring. For systems that use 24V control power, this High Voltage DC Contactor fits naturally into the control architecture.

Product Positioning

GX14CCB is positioned as a rugged High Voltage DC Contactor for 350A current paths in 800VDC-class equipment. It is well suited for electric utility vehicles, emergency response platforms, construction equipment, heavy trucks, lift systems, battery-powered service machines, and industrial DC power modules. These applications need a High Voltage DC Contactor that can isolate the battery pack or load circuit without requiring delicate mounting conditions.

Compared with lower-current contactors, GX14CCB offers a stronger 350A capacity while keeping a compact GX14 footprint. Compared with 12V coil versions, this High Voltage DC Contactor is better suited to platforms that already standardize on 24VDC control power. The auxiliary contacts give the controller an independent feedback path, allowing machine logic to verify whether the High Voltage DC Contactor has opened or closed before enabling drive, charge, or service functions.

Features and Benefits

The sealed design is one of the main benefits of GX14CCB. A High Voltage DC Contactor used on mobile equipment may be exposed to moisture, dust, road debris, vibration, and temperature variation. Hermetic sealing helps protect the switching chamber and supports long service life in demanding field conditions. This makes the GX14CCB High Voltage DC Contactor suitable for environments where an open contactor would be more vulnerable.

The 24VDC coil simplifies integration in vehicles and industrial equipment that already use a 24V auxiliary system. A High Voltage DC Contactor with a matching coil voltage reduces the need for extra power conversion and simplifies harness design. The auxiliary contacts improve control confidence because the machine controller can monitor contactor state instead of relying only on the command signal.

The 48-inch lead configuration gives equipment builders more routing flexibility in battery compartments, vehicle frames, and service panels. This is useful when the High Voltage DC Contactor must be mounted close to busbars or cables while the control harness needs to reach a controller, safety relay, or service connector. Stud terminals also support practical high-current cable connection.

Applications

• Electric and hybrid mobile equipment requiring a 350A High Voltage DC Contactor.
• Emergency vehicles and utility service platforms using 24V control systems.
• Industrial battery packs that need sealed main disconnect control.
• Heavy truck auxiliary power systems and electrified equipment modules.
• Battery charging cabinets for mobile machinery and service fleets.
• High-current DC distribution panels where auxiliary contact feedback is required.
• Maintenance disconnect circuits for rugged off-road and industrial machines.

Selection Guide

Select GX14CCB when the design needs a 350A High Voltage DC Contactor, 800VDC-class capability, 24VDC coil control, auxiliary contact feedback, and longer control leads. If the equipment uses a 12V control system, compare the GX14B coil versions. If the wiring harness needs a different lead configuration, compare GX14CBB or other GX14 suffix options. If the design requires more current capacity, move to a higher-current GX or GV series High Voltage DC Contactor.

Before final selection, confirm cable size, mounting space, auxiliary contact logic, coil drive capability, and fault protection. A High Voltage DC Contactor should be coordinated with fuses, precharge circuits, insulation monitoring, service disconnects, and controller timing. GX14CCB is a strong fit when the electrical design needs both rugged DC switching and feedback in a 24V-controlled equipment platform.
