Views: 233
The GVC611-3200A is a high-current, low-voltage AC vacuum contactor typically used for heavy-duty industrial switching, featuring a rated operating current of 3200A and a rated operating voltage of up to 1500V. It is designed for reliable and long-life performance in demanding electrical control applications.
Key Technical Specifications
- Rated Operating Current (Ie): 3200A.
- Rated Thermal Current (Ith): 3200A.
- Rated Operating Voltage (Ue): Up to 1500V (commonly 1140V or 1500V systems).
- Rated Frequency (fr): 50/60Hz.
- Control Voltage (Us): 220V ac/dc or customized.
- Number of Poles: 3-pole design.
- Rated Making Capacity (I): 4 times the rated operating current (4Ie) for AC-2 operation.
- Rated Breaking Capacity (Ic): 4 times the rated operating current (4Ie) for AC-2 operation.
- Electrical Life: 10,000 operations.
- Mechanical Life: 300,000 operations.
Applications
The GVC611-3200A is suitable for various applications that require frequent and reliable connection/disconnection of main circuits:
- Motor Control: Directly starting and controlling large AC motors in industrial settings.
- Power Distribution: Used in transformers and capacitor bank switching to manage high currents in power systems.
- Harsh Environments: The sealed vacuum interrupter makes it ideal for use in mining, pumping, and other demanding environments by containing the arc and preventing contamination.
- Renewable Energy: Employed in wind power and locomotive variable devices.
Features and Benefits
- Vacuum Arc Extinguishing: The use of vacuum interrupter technology ensures rapid and safe arc quenching, which prevents external arcing, enhances safety, and minimizes contact wear.
- Durability and Longevity: The sealed design and high-alumina ceramic tube construction provide excellent mechanical strength and a longer lifespan compared to air contactors, reducing maintenance needs.
- Compactness: The design eliminates the need for large arc chutes, resulting in a smaller physical footprint within electrical panels.
- Safety: By containing the electrical contacts within a vacuum, the risk of fire and explosion is significantly reduced.
