Sensata Gigavac GV122CAC

Sensata Gigavac GV122CAC is a GV12 series High Voltage DC Contactor designed for compact DC power systems that need reliable 200A switching in a 100VDC class circuit. This High Voltage DC Contactor uses a 24VDC coil, stud power terminals, flying lead control wiring, and hermetically sealed construction. For battery disconnect panels, small charging modules, DC service boxes, and industrial control cabinets, the GV122CAC High Voltage DC Contactor gives engineers a practical way to switch power without moving to a larger contactor platform.

The GV122CAC High Voltage DC Contactor is especially useful where the controller must know the contactor state. This model is listed with an NC auxiliary contact, so the High Voltage DC Contactor can support feedback logic in battery management systems, charger controllers, and safety interlock circuits. In a compact cabinet, that feedback capability can help confirm whether the main power path is open or closed before the next operating step is allowed.

Product Positioning

GV122CAC is positioned as a monitored High Voltage DC Contactor for 100VDC battery and charging architectures. It is not an oversized traction contactor for very high current EV packs, and it is not a simple signal relay. Instead, this High Voltage DC Contactor fits the middle ground where 200A switching, sealed construction, and 24VDC control power are required together.

For OEM designs that use 24V auxiliary control circuits, the GV122CAC High Voltage DC Contactor can reduce integration complexity. The coil voltage matches many industrial controllers and vehicle control modules, while the sealed body helps protect the switching chamber from dust, moisture, and service environment contamination. This makes the High Voltage DC Contactor suitable for equipment that may be opened for maintenance or installed in semi-protected locations.

Features and Benefits

The first benefit of GV122CAC is its sealed High Voltage DC Contactor construction. In battery equipment and charging panels, dust, moisture, and contamination can shorten the service life of open switching devices. A hermetically sealed High Voltage DC Contactor helps maintain a more stable contact environment and supports dependable operation in cabinets that may face vibration, temperature change, or field service exposure.

The second benefit is monitored switching. The NC auxiliary contact allows the control system to use the GV122CAC High Voltage DC Contactor as part of a supervised power path. In a battery disconnect panel, the controller may check auxiliary contact status before enabling charge, discharge, or service functions. This gives the High Voltage DC Contactor a stronger role in system logic than an unmonitored contactor.

The third benefit is installation flexibility. Stud terminals provide a secure connection for DC cables or busbar links, while flying leads give the installer room to route the coil and auxiliary wiring inside a tight enclosure. For compact charger modules and small battery cabinets, the GV122CAC High Voltage DC Contactor can be mounted close to the power path without forcing a complex harness layout.

Applications

GV122CAC is a strong High Voltage DC Contactor choice for compact battery disconnect boxes. In these systems, it can isolate a 100VDC class battery pack from downstream loads, service terminals, or charger connections. The High Voltage DC Contactor can also be used in auxiliary battery modules for mobile equipment where the control platform already uses 24VDC power.

In charging equipment, the GV122CAC High Voltage DC Contactor can control the charger output path or a battery connection point. Its NC auxiliary contact makes it useful when the charger controller must verify contactor state before closing the charging circuit. In industrial DC panels, this High Voltage DC Contactor can serve as a monitored load disconnect, service isolation contactor, or controlled connection device for a 200A power branch.

Additional applications include low-voltage energy storage cabinets, battery test fixtures, maintenance disconnect stations, DC UPS modules, and compact renewable energy support equipment. In each case, the GV122CAC High Voltage DC Contactor should be selected according to system voltage, continuous current, inrush conditions, coil supply, and protection design.

Selection Guide

Select GV122CAC when the project needs a 200A High Voltage DC Contactor, a 100VDC nominal switching class, a 24VDC coil, and NC auxiliary feedback. If the same system needs 12V or 48V control power, a different GV12 part number should be reviewed. If the application requires much higher voltage, a GX, HX, or GTM High Voltage DC Contactor may be more appropriate.

Before replacing another device with this High Voltage DC Contactor, confirm the cable lug size, mounting hole pattern, coil voltage tolerance, auxiliary contact logic, thermal environment, fault protection, and precharge requirements. A High Voltage DC Contactor should always be coordinated with the full DC system design rather than selected by current rating alone.
