Sensata Gigavac GV200CAB-1 DC Contactor

The Sensata Gigavac GV200CAB-1 is a sealed GV200 Series DC contactor designed for high-current power switching in battery and industrial DC systems. It provides a 500A contact rating, 800VDC switching capability, 24VDC coil operation, 38 cm / 15 in flying leads, and a normally open auxiliary contact. This model is suitable for electric vehicles, battery energy storage systems, industrial DC power distribution, marine power control, heavy equipment, UPS 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 GV200CAB-1 DC contactor is built for reliable high-current DC switching in demanding battery and power control systems. As part of the GV200 Series, this model provides a 500A contact current rating and up to 800VDC switching capability. It is commonly selected for electric vehicles, battery energy storage systems, industrial DC cabinets, marine battery systems, heavy-duty equipment, UPS power modules, and high-current battery disconnect assemblies.

The GV200CAB-1 uses an SPST-NO main contact arrangement, also described as 1 Form X. The main power 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 load 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 GV200CAB-1 is its hermetically sealed construction. The sealed contact chamber helps protect the internal contact system from dust, moisture, oxidation, and contaminated environments. The GV200 Series is designed for harsh operating conditions and is suitable for systems where vibration, humidity, or outdoor exposure can reduce the reliability of ordinary open-frame contactors.

This model includes a normally open auxiliary contact. The auxiliary contact can provide contactor status feedback to a controller, battery management system, or safety circuit after the main contact changes state. This is useful for diagnostics, interlock logic, and contactor position confirmation in battery disconnect and power distribution systems.

The GV200CAB-1 configuration uses a 24VDC internally suppressed coil and 38 cm / 15 in flying leads. The internal coil suppression helps simplify the control circuit by reducing the need for additional external suppression components. The flying lead format is practical for harness-based installation in vehicle battery boxes, power cabinets, and industrial assemblies.

Applications

The GV200CAB-1 DC contactor is suitable for systems that need dependable connection and disconnection of 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, material handling equipment, heavy-duty vehicles, and industrial automation systems.

In a battery system, the Sensata Gigavac GV200CAB-1 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 500A current rating and 800VDC switching capability make it suitable for high-current platforms where sealed construction, auxiliary feedback, and low coil power are required.

Why Choose Sensata Gigavac GV200CAB-1

The Sensata Gigavac GV200CAB-1 is a strong option when the system requires 500A current capacity, 800VDC switching voltage, 24VDC coil operation, sealed construction, 15 in flying leads, and a normally open auxiliary contact. Compared with contactors without auxiliary feedback, this model gives the control system an additional status signal for diagnostics or interlock logic.

For replacement and maintenance projects, GV200CAB-1 should be selected when the original system requires GV200 Series performance with 500A contact rating, 800VDC maximum switching voltage, 24VDC coil voltage, 38 cm / 15 in flying leads, and SPST normally open auxiliary contact. Before ordering, confirm coil voltage, auxiliary contact logic, load current, switching voltage, mounting space, and terminal requirements.
