Sensata Gigavac GV122CAC DC Contactor

The Sensata Gigavac GV122CAC is a sealed hermetic DC contactor from the GV12 Series, designed for 200A current switching in 100VDC nominal power systems. It uses a 24VDC control coil, side chassis mounting, stud and wire lead termination, 38 cm / 15 in flying leads, and a normally closed auxiliary contact. This model is suitable for EV battery systems, low-voltage battery packs, industrial DC power distribution, marine power control, material handling equipment, and OEM battery disconnect modules. In this model, 100VDC refers to the main contact switching voltage, while 24VDC refers to the coil voltage used to operate the contactor.

Product Description

The Sensata Gigavac GV122CAC DC contactor is designed for reliable low-voltage, high-current DC switching in battery and power control systems. As part of the GV12 Series, this contactor provides a 200A contact current rating and 100VDC nominal switching voltage. It is a practical choice for battery disconnect circuits, electric vehicle auxiliary power systems, material handling equipment, industrial DC cabinets, marine battery systems, and OEM control modules.

The GV122CAC uses an SPST-NO main contact arrangement, also described as 1 Form X. The main power contact remains open when the coil is not energized and closes when the 24VDC coil receives the correct control signal. This allows a lower-voltage control circuit to manage a higher-current DC load path. The 100VDC value belongs to the main switching circuit, while the 24VDC value belongs only to the coil control circuit.

A key advantage of the Sensata Gigavac GV122CAC is its sealed hermetic construction. The sealed body helps protect the internal contact system from dust, humidity, oxidation, and harsh operating environments. This makes the GV122CAC suitable for mobile equipment, outdoor battery systems, industrial control cabinets, and vehicle platforms where vibration, moisture, and contamination can reduce the service life of ordinary open-frame contactors.

This version uses side chassis mounting with stud and wire lead termination. Compared with PCB pin versions, the wire lead configuration is useful when the contactor needs to be connected into a vehicle harness, control box, or power distribution assembly. The C auxiliary option indicates a normally closed auxiliary contact, which can support status feedback, interlock logic, or battery management system monitoring.

Applications

The GV122CAC DC contactor is suitable for systems that need dependable connection and disconnection of DC battery, load, or charging circuits. Typical applications include EV low-voltage battery disconnect units, electric forklifts, AGV equipment, battery management systems, DC power cabinets, renewable energy control boxes, marine battery switching, UPS systems, and industrial automation equipment.

In a battery system, the Sensata Gigavac GV122CAC can be used as a main contactor, charge contactor, load disconnect contactor, or safety isolation device depending on the circuit design. Its 200A current rating and 100VDC switching voltage make it suitable for low-voltage, high-current platforms where sealed protection, auxiliary feedback, and stable switching performance are required.

Why Choose Sensata Gigavac GV122CAC

The Sensata Gigavac GV122CAC is a strong option when the system requires 200A current capacity, 100VDC switching voltage, 24VDC coil operation, side mounting, wire lead termination, and a normally closed auxiliary contact. Compared with versions without auxiliary feedback, this model gives the control system an additional status signal for diagnostics or interlock design.

For replacement and maintenance projects, GV122CAC should be selected when the original design requires GV12 Series performance with 200A current rating, 100VDC nominal switching voltage, 24VDC coil voltage, side chassis mounting, 38 cm / 15 in flying leads, and SPST normally closed auxiliary contact. Before ordering, confirm coil voltage, auxiliary contact logic, mounting style, terminal type, load current, and system voltage.
