High-Current 3200A AC Vacuum Contactor - GVC611-3200A

Date: 2026.02.05 Views: 452

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.
