Vacuum Contactor 250A and 400A

The GVC20 series vacuum contactors are suitable for AC 50-60Hz power network systems with main circuit rated currents of 250A and 400A. They are designed for remote switching, frequent starting, and control of AC motors, transformers, and capacitor banks. This series of vacuum contactor features a fully enclosed design, a elegant appearance, stable and reliable performance, maintenance-free operation, and a long service life. They are the ideal replacement for old-fashioned vacuum contactor.

• The ambient air temperature for the installation of the contactors ranges from -25°C to 40°C. The altitude of the contactor's installation location should not exceed 2000m.
• The control power supply voltage can be AC/DC, with options of 36V, 110V, 220V and 380V. Customization is also available according to user requirements.
• The control circuit can be operated using either a DC electromagnetic system or a DC permanent magnet system. In the case of an AC control power supply, it is supplied to the coil through a rectifier bridge.
• The standard types of auxiliary circuit contacts include electric holding type (two normally open and one normally closed) and permanent magnet type (one normally open and one normally closed). Customization is also possible based on customer requirements.
• The maximum specified heating current for the auxiliary switch contacts is 5A.
