Product Description

The Sensata Gigavac GX23CAB is a 350 A stand-up DC contactor built for reliable switching from low-voltage DC circuits up to 800VDC. As part of the GX23 Series, it uses a compact vertical mounting layout with an integrated safety cover, making it useful where a stand-up form factor fits the busbar, cable, or enclosure design better than a bottom-mount contactor. It is suitable for electric vehicles, hybrid vehicles, battery systems, industrial DC equipment, marine power systems, heavy-duty vehicles, renewable energy systems, and power management cabinets.

GX23CAB uses a normally open main contact. In the de-energized state, the main power circuit is open and the load is isolated. When the 24VDC coil is energized, the contactor closes and current flows through the power terminals. When coil power is removed, the contactor opens again. This makes the GX23CAB suitable for main battery disconnect, charge contactor, inverter input control, DC bus switching, auxiliary load control, and high-current load isolation.

The complete model number should be kept in product listings and replacement records. “GX23” identifies the 350 A, 800VDC stand-up contactor family. The first “C” indicates the 24VDC coil version with internal coil suppression. The “A” indicates 15 inch flying leads. The final “B” indicates an SPST normally open auxiliary contact. The main contact and auxiliary contact are both normally open, but the main contact switches the power circuit while the auxiliary contact provides low-current status feedback.
