Product Description
GIGAVAC GVB351BAB Bidirectional Contactor
GIGAVAC GVB351BAB 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 GVB351BAB Bidirectional Contactor - 500A 1000VDC
The GIGAVAC GVB351BAB is a high-performance bidirectional DC contactor engineered for robust switching in demanding high-voltage environments. Featuring a hermetically sealed, gas-filled design, it offers significantly lower resistance than non-hermetic alternatives, resulting in superior system efficiency and minimal heat generation. This 500A/1000VDC rated contactor is position-insensitive and equipped with high-efficiency dual DC coils with built-in suppression, making it an ideal choice for battery-powered systems. Its advanced arc-cooling capabilities and IP67/IP69K protection ensure reliable operation in DC fast charging and energy storage applications.
