Product Outline
HGLD automtic change-over switch (ATSE) integrates switch and logic control. Thus it is not
Necessary to provide external controller. This truly electrome chemically integrated automatic
Change-over switch has the following functions, such as voltage detection, frequency detection,
Communication inferface, electrical and mechanical interlocking etc., So automatic control,
Electrical remote control and emergency manual control can be performed.
The operation is carried out through the logic control control board, which gives various
Commands to control the motor and gear-box. The motor drives the accelerator which can take
Seich-spring power accumulating and instantaneous releade, swifty truns making and breaking the
Circuit or makes circuit switching. The visible operation status can help you to perform safe
Separation, increasing extremely the various electrical and mechanical performance.
The shell of switch HGLD 1, HGLD 2 is made of metal, being small and compact, While the shell
Of swich HGLD is made of different materials: Its control section is made of metal, but the
Switching section is made of glassfibre unsaturated polyester resin, having stronger dielectric
Property and protective capability as well as safe operation performance
The kind of switch is suitable for the automatic change-over of the main power source and the
Secondary power supply system or the automatic change-over and safe separation of the 2sets
Of load-equipment. This kind of switch has beautiful, novel and simple structure, a small volume
But complete functions, being the best choice among congener of products.
Example for model selection
HGLD1-100/A III~380V In 50A
Automatic change-over switch, Appointed clarify current is 100A, AC rate voltage 380V,
Rate current 50A, 4poles(3 poles +on and off neutral pole), Suitable forautomatic change
And automatic recovery of municipal power oil generator power supply system.

HGLD Series Automatic Change-Over Switch Complies with the Following Standards:
IEC60947-1(1998)Low-voltage switchgear and controlgear, part one: General Rules IEC60947-3(1999) Low-voltage
Switchgear and control gear, switches, disconnetors, switch-disconnectors and fuse-combination
IEC60947-6(1999)Low-voltage switch equipment and control equipment multi-function-switch automatic change-over switch electrical device
National Standard:
GB/T14048.1-2002Low-voltage switchgear and controlgear, part one: General Rules

GB14048.11-2002Low-voltage switch equipment and control equipment multi-function-switch automatic changeover switch electrical device

HGLD series automatic transfer switch is mainly used in AC 50Hz, rated voltage of 380V DC rated voltage of 220V, load switch a preparation of a master or mutual standby power supply switching system and the city electricity and the generator rated current of 16 to 3200A distribution or motor network. Can also be used for less frequent switching on and off circuit and circuit isolation in.
Products are widely used in fire fighting, hospitals, banks, and other high-rise buildings are not allowed to cut off power supply of important places of transmission and distribution system and automation system
The switch has 3 poles or 4 poles (3 poles+on or off neutral pole). 
27 current grades can be divided into 16A\20A\25A\32A\40A\50A\63A\80A\100A\125A\160A\200A\225A\250A\315A\350A\400A\450A\500A\630A\800A\1000A\1250A\1600A\2000A\2500A\3200A.
