Product Description
GIGAVAC GVB351CBB Bi-Directional Contactor
- 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 GVB351CBB Bi-Directional Contactor - 500A 1000VDC
The GIGAVAC GVB351CBB is a high-performance bi-directional DC contactor engineered for efficient power switching in high-voltage energy systems. Featuring a gas-filled hermetic design, it offers significantly lower contact resistance than non-hermetic alternatives, reducing heat generation and maximizing system efficiency.
