Product Description

GN19-12, 12C Series Indoor High-Voltage Disconnect Switches

GN19-12, 12C Series Indoor High-Voltage Disconnect Switches

The GN19-12, 12C series indoor high-voltage disconnect switches are designed for indoor use with a rated voltage of 12kV, three-phase AC 60Hz. These switches are used for dividing and closing circuits under voltage and no load conditions.

Features:

• Three-pole type design


• Consists of base frame, rotating shaft, lever, porcelain pillar insulator, gate knife, and connection board


• Conductive part fixed on base by pillar insulators


• Improved mechanical strength and heat dissipation area

Working Principle:

The conductive part of the disconnect switch is fixed on the base by insulators, with each phase connected to the tie insulator and spindle. The connecting contact knife is composed of two slotted copper plates for enhanced stability.

Model Meaning:

The model numbers indicate the type and capacity of the disconnect switch, with variations in features such as magnetic locking plates for enhanced safety.
