Description

HD11F series (Model G)

Open knife switch with protective cover

Open knife switch

Scope of application

HD11F (type G) series switch is a new product developed by our company on the basis of HD11F. It is an ideal substitute for the old HD11F series, which greatly improves the protective performance for life safety and prevents accidental electric shock.

This series of products are mainly used in low-voltage distribution equipment for infrequent manual connection, disconnection and isolation of power supply.

This product conforms to GB/T14048.3 IEC60947-3 standard.

Normal working and installation conditions

The ambient air temperature is not higher than +40 ℃ and not lower than -5 ℃.

The altitude of the installation site shall not exceed 2000m.

Humidity: when the maximum temperature is +40 ℃, the relative humidity of the air does not exceed 50%. At a lower temperature, a higher relative humidity can be allowed, such as 90% at 20 ℃. Corresponding measures should be taken for the occasional condensation due to temperature changes.Open knife switch

The pollution level of the surrounding environment is level 3.

The switch shall be installed in a place without significant shaking, shock vibration and rain and snow invasion. At the same time, the installation place shall be free of explosive dangerous medium, and the medium shall be free of gas and dust sufficient to corrode metal and damage insulation.

The insulating material of the product can reach flame retardant VO level.
