Product Description

Important Features

Intuitionistic Operation Interface

All the operation labels are marked on the interface. Operator can operate the switchgear according to the instruction.

New Structure For Enclosure

The enclosure is made up of high density and anti-corrosive zincified steel plate. The whole panel is separated into three individual compartments: busbar compartment, function compartment, and cable compartment. These three compartments are separated by each other to prevent from default extension.

Simple Busbar Connecting System

The busbars are connected without holes.

Innovational Contact Structure

The conversion among the connecting, testing and disconnecting position is implemented by moving primary and secondary contactors, not by moving the whole drawers. The primary and secondary contactors are designed with modules according to the capacity.

New Propelling Mechanism And Mechanical Interlock

There is perfect mechanical interlock between the propelling mechanism and switch to ensure the safety of operator.There is also the interlock between the switch and the door.
