Sensata Gigavac GV141FAX DC Contactor

The Sensata Gigavac GV141FAX is a sealed hermetic DC contactor from the GV14 Series, designed for 400A current switching in 100VDC nominal power systems. It uses a 48VDC control coil, upright chassis mounting, stud and wire lead termination, 38 cm / 15 in flying leads, and no 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 48VDC refers to the coil voltage used to operate the contactor.

Product Description

The Sensata Gigavac GV141FAX DC contactor is built for reliable low-voltage, high-current DC switching in battery and power control systems. As part of the GV14 Series, this contactor provides a 400A contact current rating and 100VDC nominal switching voltage. It is a practical choice for battery disconnect circuits, electric vehicles, material handling equipment, marine battery systems, industrial DC cabinets, and compact OEM power modules.

The GV141FAX 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 48VDC coil receives the correct control signal. This allows a lower-voltage control circuit to manage a high-current DC load circuit. The 100VDC value belongs to the main switching path, while the 48VDC value belongs only to the coil circuit.

A key advantage of the Sensata Gigavac GV141FAX 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 GV141FAX 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 stud and wire lead termination for harness-based installation. 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 X auxiliary option indicates no auxiliary contact, so GV141FAX is best suited for systems where separate contact feedback is not required or where status monitoring is handled by another circuit.

Applications

The GV141FAX DC contactor is suitable for systems that need dependable connection and disconnection of DC battery, load, or charging circuits. Typical applications include EV battery packs, electric forklifts, AGV equipment, low-voltage 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 GV141FAX can be used as a main contactor, charge contactor, load disconnect contactor, or safety isolation device depending on the circuit design. Its 400A current rating and 100VDC switching voltage make it suitable for low-voltage, high-current platforms where sealed protection and stable switching performance are required.

Why Choose Sensata Gigavac GV141FAX

The Sensata Gigavac GV141FAX is a strong option when the system requires 400A current capacity, 100VDC switching voltage, 48VDC coil operation, upright chassis mounting, 15 in wire leads, and no auxiliary contact. Compared with versions that include auxiliary feedback, this model is simpler for designs where the controller does not need a separate auxiliary signal.

For replacement and maintenance projects, GV141FAX should be selected when the original design requires GV14 Series performance with 400A current rating, 100VDC nominal switching voltage, 48VDC coil voltage, stud and wire lead termination, and no auxiliary contact. Before ordering, confirm coil voltage, auxiliary contact requirement, mounting style, terminal type, load current, and system voltage.
