GVB351CAB Bidirectional Contactor

GVB351CAB – Bidirectional DC Contactor by Gigavac

The GVB351CAB from Gigavac is a bidirectional contactor capable of switching current in both directions – from positive to negative and vice versa. Unlike directional contactors that only operate in one direction, bidirectional contactors like the GVB351CAB are ideal for systems requiring flexibility and reverse current flow.

This compact, sealed contactor features built-in coil suppression and a hermetic chamber filled with arc suppression gas, which enables safe interruption of high fault currents while preventing contact oxidation. Thanks to its low heat generation, it operates with high efficiency and is ideal for battery-powered systems.
