QGLD AUTOMATIC CHANGE-OVER SWITCH (ATSE)  integrates switch and logic control. Thus it is not necessary to provide external. This truly electrome chanically intergrated automatic chang-over switch has the following functions such as voltage detection, frequency detection, communication interface, electrical and mechanical interlocking ect. ,So, automatic control, electrical remote control and emergency manual control can be performed.

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.

Performance and characteristic:

1 It adopted double complex contact, horizontal and vertical type framework, Micro motor pre-saving and Micro electronic control technical, basically, it have come to ‘Zero’ arc (No Arc Chute);

2 It adopt reliable machine interlock and electric interlock, the executive union parts adopt independency overload disconnect switch, it makes more reliable and safety;

3 Operate overload disconnect switch change over adopt singleness electromotor drive, switch over smooth and reliable, no noise, little wallop;

4 It include main power close, standby power separate; main power separate; standby power close; main, standby power all break off and steady working(Ⅰ-0-Ⅱ)

5 Four king of operation function: emergency manual operation, electromotion remote control operation, automatic control stage emergency off operation, automatic control operation.
