GV244FPX DC contactor is a Sensata-Gigavac GV24 series sealed DC power contactor designed for high-voltage, high-current DC switching systems. This 400A DC contactor is rated for 800VDC nominal switching voltage and uses a 48VDC coil, making it suitable for energy storage systems, charging equipment, industrial DC buses, renewable energy platforms, and high-voltage battery power control. As an 800VDC contactor with PC pin termination, GV244FPX DC contactor is useful when engineers need a compact sealed contactor that supports high voltage, high current, and efficient 48V control integration.

The GV244FPX DC contactor uses an SPST-NO contact arrangement, also described as 1 Form X. The main circuit remains open when the coil is not energized and closes when the 48VDC coil is powered. This normally open switching structure is widely used for high-voltage DC load control, battery isolation, DC bus connection, equipment protection, and safe power distribution. For buyers looking for a 400A DC contactor in the GV24 family, GV244FPX DC contactor provides a strong combination of 800VDC switching capability, 48V coil control, sealed construction, and compact PC pin termination.

Product Overview

GV244FPX DC contactor is different from lower-voltage GV14 models because it is designed around an 800VDC contactor platform. Many EV-related systems, energy storage cabinets, solar power systems, and high-voltage industrial DC assemblies operate at voltage levels that require more than a 100VDC contactor. In these applications, a 400A DC contactor must not only carry current but also support safe and reliable switching in high-voltage DC circuits. GV244FPX DC contactor is positioned for these demanding 800VDC power paths.

The 48VDC coil contactor configuration is another important selection factor. Some high-voltage systems use 48V control architecture for better compatibility with industrial power electronics, battery management equipment, energy storage controls, telecom power systems, and larger DC control platforms. A 48VDC coil contactor can be easier to integrate when the control side already uses a 48V bus. GV244FPX DC contactor allows the control circuit to operate from 48VDC while the main contacts handle high-current 800VDC class switching.

Key Specifications

Features and Benefits

800VDC Switching for High-Voltage DC Systems

The main value of GV244FPX DC contactor is its 800VDC voltage class combined with 400A current capacity. An 800VDC contactor is commonly required in high-voltage battery systems, energy storage cabinets, EV charging equipment, renewable energy conversion systems, and industrial DC distribution platforms. GV244FPX DC contactor supports applications where lower-voltage contactors are not appropriate and where a compact high-voltage sealed contactor is needed for reliable power control.

400A Current Rating for Demanding Loads

As a 400A DC contactor, GV244FPX DC contactor is designed for systems that must carry and control substantial DC current. A 400A DC contactor can be used in main DC bus control, battery output switching, high-current load isolation, and power distribution assemblies. The 400A rating makes GV244FPX DC contactor suitable for heavier power circuits than 150A or 250A contactors, while still keeping the package more compact than some larger 500A or 600A contactor families.

48VDC Coil for Industrial and Energy Control Platforms

GV244FPX DC contactor uses a 48VDC coil, which makes it useful for systems built around 48V control architecture. The 48VDC coil contactor format is common in energy storage controls, telecom power equipment, larger battery systems, industrial control platforms, and DC power electronics. When a system already has 48V control power, selecting a 48VDC coil contactor can reduce conversion requirements and simplify the electrical design. GV244FPX DC contactor therefore fits applications where the high-voltage switching side and the 48V control side must work together.

Sealed Construction for Harsh Operating Conditions

GV244FPX DC contactor uses hermetically sealed construction to help protect the internal contact system from dust, moisture, humidity, and harsh environmental conditions. In high-voltage DC systems, contamination and unstable contact performance can create reliability risks. A sealed 800VDC contactor helps support stable operation in equipment exposed to temperature variation, vibration, outdoor enclosures, industrial cabinets, or energy storage sites. This is one reason a sealed 400A DC contactor is often preferred over open-frame switching devices in demanding applications.

PC Pin Termination for OEM Integration

GV244FPX DC contactor uses PC pin termination, which can support compact OEM integration and reduce loose wiring in controlled assemblies. For designers building high-voltage modules, power distribution units, or energy storage control sections, PC pins may simplify assembly and improve layout consistency. When selecting GV244FPX DC contactor, engineers should confirm that the PC pin layout, clearance, creepage distance, mounting position, thermal design, and bus structure are suitable for the final 800VDC system.

Applications

GV244FPX DC contactor is suitable for energy storage systems, EV charging equipment, high-voltage battery packs, solar and renewable energy systems, industrial DC distribution, power conversion equipment, material handling vehicles, mobile power platforms, and compact high-voltage control modules. Because it is a 400A DC contactor, it can be used where a high-current DC path must be switched, isolated, or connected under controlled conditions. Because it is an 800VDC contactor, it is suitable for systems that operate far above the voltage range of lower-voltage GV14 contactors.

In energy storage systems, GV244FPX DC contactor can help control the connection between battery modules, a DC bus, and power conversion equipment. In charging equipment, this 800VDC contactor may support controlled switching within suitable high-voltage DC circuits. In renewable energy platforms, the 400A DC contactor rating can support power path control for DC-side distribution. In industrial DC systems using 48V control power, the 48VDC coil contactor configuration helps align the contactor with the control architecture already used in the cabinet or power module.

Selection Guide

Choose GV244FPX DC contactor when the application requires a Sensata-Gigavac GV24 series contactor with 400A rating, 800VDC switching voltage, 48VDC coil, SPST-NO contact form, sealed construction, and PC pin termination. If the system uses 12V control power, compare GV244BPX. If the system uses 24V control power, compare GV244CPX. If the system needs a 48VDC coil contactor for an 800VDC power path, GV244FPX DC contactor is the more suitable option within this part-number family.

GV244FPX DC contactor should not be selected only by current rating. A correct selection must consider maximum DC voltage, continuous current, switching duty, coil drive voltage, fault current behavior, thermal rise, mounting position, termination style, and safety requirements. For applications above 400A or with a higher voltage class than 800VDC, engineers should compare GV35, GVB35, HX, GXV, or other high-voltage contactor families. For lower-voltage systems around 100VDC, GV14 series models may be more appropriate than an 800VDC contactor.
