FDQ3-63 Miniature Circuit Breaker Automatic Transfer SwitchDetailed product description：

FDQ3-63 miniature circuit breaker automatic transfer switch is a device used for automatic switching between mains power and generators in the power grid system, which can ensure continuous power supply. Suitable for important occasions that require continuous power supply, such as residential, hospital, hotel, bank, school, municipal, metallurgical, petrochemical, transportation, communication power supply, etc.
Compliant with GB/T1408.11 Low voltage switchgear and control equipment Part 6-1: Multifunctional electrical switching devices

Structural characteristics of FDQ3-63 miniature circuit breaker automatic transfer switch
Miniaturization, CB level;
Small circuit breakers as main switches (C65, C45, etc.);
Single motor operation has mechanical interlocking;
Permanent magnet synchronous motor, stable operation;
Adopting a unique patented transmission mechanism to ensure that the closing is fully in place;
Separate the status indication from the motor in place power-off switch to ensure the accuracy of the indication and the reliability of the motor power-off;
The use of plastic casing packaging enhances the protective capability of the mechanism, reduces the influx of moisture, and improves reliability;
ODM customers can install circuit breakers themselves quickly and conveniently. Simply connect the sampling line to the switch, install several components as a whole, and cover the casing to complete the installation.
