Sensata Gigavac GV244PPX DC Contactor Overview

The Sensata Gigavac GV244PPX is a sealed hermetic DC contactor from the GV24 Series, designed for high-current switching in 800VDC nominal power systems. It provides a 400A contact rating, 12-24VDC coil operation, PC pin termination, and no auxiliary contact. This model is suitable for EV battery systems, battery energy storage systems, DC charging equipment, industrial power distribution, marine power control, and OEM high-voltage battery disconnect modules. In this model, 800VDC refers to the main contact switching voltage, while 12-24VDC refers to the coil control voltage used to operate the contactor.

Product Description

The Sensata Gigavac GV244PPX DC contactor is designed for reliable high-voltage DC power switching in compact battery and power control systems. As part of the GV24 Series, this model supports 800VDC nominal switching voltage and a 400A contact current rating. It is a strong choice for electric vehicles, energy storage systems, charging equipment, industrial DC cabinets, marine battery systems, and high-voltage power distribution modules.

The GV244PPX uses an SPST-NO main contact form, also described as 1 Form X. The main contact remains open when the coil is not energized and closes when the 12-24VDC control coil receives the correct control input. This allows a lower-voltage control circuit to manage a high-voltage DC load circuit. The 800VDC value is the main power switching rating, while 12-24VDC is the coil control voltage range.

A key feature of the Sensata Gigavac GV244PPX is its sealed hermetic construction. The sealed body helps protect the internal contact system from dust, moisture, oxidation, and harsh operating environments. This is important in vehicle platforms, outdoor energy systems, industrial cabinets, and mobile equipment where vibration, humidity, and contamination can reduce the life of ordinary open-frame contactors.

The GV244PPX uses PC pin termination and is listed in the GV24 PCB M8 configuration family. This makes it suitable for OEM assemblies where compact installation, repeatable production, and reduced wiring complexity are important. The “X” suffix indicates that this version does not include an auxiliary contact, so it is best suited for applications where separate auxiliary feedback is not required or where contactor status is monitored by another circuit.

Applications

The GV244PPX DC contactor is suitable for high-voltage DC systems that need dependable connection and disconnection of battery, load, or charging circuits. Typical applications include EV battery packs, electric forklifts, AGV systems, battery management systems, DC charging equipment, renewable energy storage, UPS battery cabinets, marine electric propulsion, and industrial DC distribution.

In battery systems, the Sensata Gigavac GV244PPX can be used as a main positive contactor, main negative contactor, charge path contactor, load disconnect contactor, or safety isolation device depending on the system design. Its 400A current rating and 800VDC switching voltage make it suitable for high-voltage platforms where compact size, sealed protection, and stable switching performance are required.

Why Choose Sensata Gigavac GV244PPX

The Sensata Gigavac GV244PPX is a practical option when the design requires 400A current capacity, 800VDC switching voltage, 12-24VDC coil operation, sealed construction, PC pin termination, and no auxiliary contact. Compared with lower-voltage contactors, this model is better matched to high-voltage battery and DC bus systems. Compared with non-sealed contactors, the hermetic structure helps improve reliability in outdoor, mobile, and vibration-prone environments.

For replacement and maintenance projects, GV244PPX should be selected when the original system requires GV24 Series performance with 400A contact rating, 800VDC nominal switching voltage, 12-24VDC coil voltage, PC pins, and no auxiliary contact. Before ordering, confirm the coil control method, mounting requirements, auxiliary contact requirement, main terminal design, and system current rating.
