Lugao takes pride in being GN27-40.5 Indoor High Voltage Disconnect Switch manufacturer,Our GN27-40.5 indoor high-voltage disconnect switch features a three-phase common chassis structure with a vertical rotary guillotine type design. On the fracture side, the static contact is configured as a swing-type multi-contact piece, offering advantages such as low contact pressure, reduced wear, a large heat dissipation area, and minimal operating torque for each contact.

The chassis structure is designed to optimize insulating properties and provide high mechanical strength. To cater to diverse needs, this series includes variations such as flat type, wall type, and configurations with a grounding knife. Notably, these isolating switches can be installed horizontally, vertically, or obliquely, providing flexibility in installation options to suit various applications.

Operating Environment

1.  Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.

2.  Install and use indoors.  Altitude above sea level for operation site should not exceed 2000M.

3.  Relative humidity should not exceed 50% at max temperature +40.  Higher relative humidity is allowed at lower temperature.  Ex. 90% at +20.  But in view of the temperature change, it is possible that moderate dews will produce casually.

4.  Installation gradient not exceed 5.

5.  Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.

6.  Any specific requirement, consult with manufactory.
