Automatic Change-Over Switch (HKKQ3)

Product Description

HKKQ3 qutomatic change-over switch(ATSE)integrates switch and logic control, thus it is not necessary toprovide external controller. This truly electromechani-cilly integrated automatic change-over switch has the following functions such as voltage detection, frequency detection, communication interface, 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 board, which gives various commands to control the motor and gear-box. The motor drives the accelerator which can take switch-spring power accumulating and instantaneous release, swiftly turns making and breaking the circuit or makes circuit switching. The visible operation status can help you to perform safe operation, increasing extremely the various electrical and mechanical performance.

The shell of switch HKKQ3 is designed into small and compact construction. While the shell of switch HKKQ3 is made of different materials: Its control section is made of metal, but the switching section is made of glass-fibre unsaturated polyester resin, having stronger dielectric property and protective capability as well as safe operation performance. This kind of switch is suitable for the automatic change-over of the main power source and the secondary power source of the power supply system or the automatic change over and safe separation of the 2 sets of load-equipment. This kind of switch has a beautiful, movel and simple structure, a small volume but complete functions, being the best choice among congeneric of products. HKKQ3 series had been already passed the detection of EMC.
