Product Description
GIGAVAC GVB351CAB Bidirectional Contactor
GIGAVAC GVB351CAB Bidirectional Contactor offers wide range of options for various application fields with its robust structure. With its bidirectional structure, this contactor provides the best solution for your switching applications.
- Gas filled design offers lower resistance than non-hermetic switches resulting in higher system efficiency and less heat generation. Meet IP67 level.
- Suppression gas allows high fault interrupt capability and prohibits oxidation---Strong capability of cooling arc, rapidly breaking current.
- High Efficiency Dual DC Coils - Very low 12, 24, or 48 VDC continuous coil power with no EMI emissions or cross-talk on your system control power. Ideal for battery powered systems or where low power is needed.
- Built-in coil suppression for all DC coils - Saves you engineering time and parts cost to add external coil suppression.
- Not position-sensitive - can be mounted in any position for ease of installation.
GIGAVAC GVB351CAB Bidirectional Contactor - 500A 1000VDC (24V Coil)
The GIGAVAC GVB351CAB is a premium bidirectional DC contactor designed for high-power switching in demanding 24VDC control systems. Utilizing a hermetically sealed, gas-filled chamber, it achieves significantly lower contact resistance than traditional switches, resulting in higher system efficiency and reduced heat generation. This 500A / 1000VDC rated unit features advanced arc-cooling suppression and is not position-sensitive, allowing for flexible installation in any orientation. With its IP67/IP69K environmental rating and built-in coil suppression, the GVB351CAB is a highly reliable solution for next-generation energy storage, electric mobility, and DC fast-charging infrastructure.
