Sensata Gigavac GV224BPX

Sensata Gigavac GV224BPX is a 200A 800VDC High Voltage DC Contactor from the GV22 series, designed for energy storage systems, DC power cabinets, battery modules, and compact high-voltage DC switching assemblies. This High Voltage DC Contactor uses an SPST-NO main contact arrangement, a 12VDC coil, PCB pin termination, no auxiliary contact, and sealed construction. For OEM designs that need a reliable High Voltage DC Contactor for ESS battery isolation, DC bus control, and protected power switching, GV224BPX provides a compact and practical configuration.

As a GV22 series High Voltage DC Contactor, GV224BPX is built for 800VDC-class power systems where controlled connection and disconnection are required. The 200A current rating makes it suitable for medium-power energy storage cabinets, battery strings, DC distribution branches, and power conversion support circuits. Its sealed construction helps protect the contact system from dust, moisture, and contamination, supporting more stable performance in electrical cabinets and industrial energy equipment.

Product Positioning

GV224BPX is positioned as a High Voltage DC Contactor for ESS and battery power control applications that need 200A current capacity, 800VDC voltage capability, and a 12VDC control coil. Compared with higher-current GV24 models, this part is better matched to systems where compact size and 200A switching capacity are sufficient. Compared with auxiliary-contact versions, GV224BPX is a simpler no-auxiliary-contact configuration for systems that do not require direct contactor feedback.

This High Voltage DC Contactor is useful for battery pack isolation, DC bus switching, service disconnect circuits, charger interface control, and protected power branch switching. In energy storage equipment, a normally open contactor can help keep the power path open during shutdown, maintenance, or fault response, then close only when the control system commands operation.

Features and Benefits

The main benefit of GV224BPX is its combination of 800VDC voltage capability, 200A current rating, and compact PCB-oriented termination. As a High Voltage DC Contactor, it can support controlled switching in battery and ESS circuits where ordinary relays are not suitable. The normally open contact design keeps the main circuit open until the 12VDC coil is energized, supporting safer start-up, shutdown, and maintenance procedures.

The 12VDC coil makes this High Voltage DC Contactor easy to integrate into systems that already use a 12V control supply. This is common in battery management equipment, auxiliary control boards, compact DC cabinets, and equipment with low-voltage control electronics. PCB pin termination helps reduce wiring complexity and supports repeatable OEM assembly.

The sealed construction is important for energy storage and DC power equipment because electrical cabinets may face humidity, dust, temperature changes, and long operating hours. A sealed High Voltage DC Contactor helps protect the internal contact system from environmental contamination. This supports more consistent switching performance in ESS cabinets, industrial battery rooms, charging support modules, and power conversion assemblies.

Applications

GV224BPX is especially suitable for energy storage systems, which is the recommended application focus for this model. In an ESS cabinet, this High Voltage DC Contactor can be used to isolate a battery string, connect a DC bus, control a charger interface, or disconnect a protected power branch during service and fault events. The 200A current rating and 800VDC voltage capability make it suitable for medium-power storage and conversion equipment.

This High Voltage DC Contactor can also be used in DC distribution modules, backup power systems, battery test equipment, compact charging equipment, and industrial power-control assemblies. In these applications, GV224BPX supports controlled energization and isolation of high-voltage DC circuits when paired with suitable fusing, precharge circuits, and control logic.

Selection Guide

Before selecting GV224BPX, confirm the DC bus voltage, continuous current, peak current, inrush current, and switching duty. This High Voltage DC Contactor is intended for 800VDC-class applications and 200A current paths, but the final system must still account for load type, DC arc behavior, thermal rise, creepage and clearance, and protective fuse coordination. Battery and inverter circuits often require a precharge path before the main contactor closes.

The coil supply should also be reviewed. GV224BPX uses a 12VDC coil, so it should be selected for systems with a stable 12V control source. If the equipment uses 24VDC or 48VDC control power, another GV22 configuration may be more appropriate. If feedback is required, choose a related GV22 model with auxiliary contacts, because GV224BPX is listed as a no-auxiliary-contact version.

FAQ

Is GV224BPX normally open?

Yes. GV224BPX is an SPST-NO High Voltage DC Contactor, so the main contacts remain open until the 12VDC coil is energized.

What current and voltage does GV224BPX support?
