Sensata Gigavac GV244CPX

Sensata Gigavac GV244CPX is a 400A 800VDC High Voltage DC Contactor for charging modules, industrial DC distribution panels, battery cabinet power boards, and compact equipment assemblies that use PCB-style control integration. This GV24 series High Voltage DC Contactor uses a 24VDC coil, SPST-NO main contact arrangement, PCB pins, chassis mounting, hermetically sealed construction, and no auxiliary contact. GV244CPX is a useful High Voltage DC Contactor when the design needs 400A switching but does not require auxiliary feedback.

This page is written around PCB-pin cabinet integration and no-auxiliary-contact selection. Many product pages for GV24 contactors sound similar because the current and voltage class are shared. For GV244CPX, the important distinction is the 24V coil, PCB pin termination, and X suffix with no auxiliary contact. In a charger module or DC power distribution cabinet, this High Voltage DC Contactor can be used where the controller already monitors current, voltage, or bus state elsewhere and does not need a separate auxiliary contact from the contactor.

Product Positioning

GV244CPX is positioned as a 400A High Voltage DC Contactor for 24V-controlled DC cabinets that favor PCB pin termination. It is suitable for compact charger assemblies, industrial DC control panels, battery interface boards, inverter service sections, and renewable energy distribution equipment. The High Voltage DC Contactor provides sealed high-current switching in an 800VDC-class design while keeping the auxiliary configuration simple.

Compared with GV244CPB, which includes a normally open auxiliary contact, GV244CPX is selected when no auxiliary contact is required. Compared with flying-lead GV241 variants, this High Voltage DC Contactor is better matched to PCB-oriented mounting and control layouts. The 24VDC coil fits standard industrial control power, making GV244CPX a practical High Voltage DC Contactor for equipment that already uses 24V relay drivers, PLC outputs, or contactor control boards.

Features and Benefits

The PCB pin termination is a major benefit of GV244CPX. A High Voltage DC Contactor in a compact cabinet may need to align with a control board, driver board, or modular power assembly. PC pins can simplify the connection between the contactor coil and the control electronics while the high-current path remains arranged around the main contactor body and power terminals.

The no-auxiliary-contact configuration is also important. Not every system needs contactor feedback from the device itself. Some designs monitor bus voltage, current sensor output, charger status, or insulation data to confirm system state. In those cases, GV244CPX offers a simpler High Voltage DC Contactor option without adding an auxiliary contact circuit that the controller will not use.

The 400A rating gives GV244CPX enough current capacity for many charger, battery, and industrial DC distribution paths. The sealed construction helps protect the contactor from dust, moisture, oxidation, and environmental contamination. For a High Voltage DC Contactor inside a charging cabinet or power conversion enclosure, this construction supports long-term switching reliability.

Applications

• Charging modules requiring a 400A High Voltage DC Contactor with 24V control.
• Industrial DC distribution panels using PCB-style control boards.
• Battery cabinet power boards where auxiliary feedback is not required.
• Inverter DC bus switching circuits in 800VDC-class systems.
• Renewable energy power conversion cabinets and DC output sections.
• Compact power assemblies that use PC pins for coil/control integration.
• Service disconnect circuits where external monitoring is already provided.

Selection Guide

Select GV244CPX when the design needs a 400A High Voltage DC Contactor, 800VDC nominal voltage class, 24VDC coil, PCB pin termination, sealed construction, and no auxiliary contact. If the system requires normally open auxiliary feedback, choose GV244CPB. If it requires normally closed auxiliary feedback, choose the corresponding CPC suffix. If the layout uses flying leads instead of PC pins, compare the GV241 series High Voltage DC Contactor variants.

Before final selection, confirm PCB clearance, creepage and spacing, coil driver capability, busbar layout, thermal rise, fuse coordination, and contactor control sequence. A High Voltage DC Contactor should be matched to the full electrical design. GV244CPX is strongest where the equipment needs a compact 24V-controlled 400A contactor and the monitoring strategy is handled outside the contactor.

FAQ
