Description
1.Application
YMQ Series automatic transfer switch (transfer switch) is developed successfully with the help of the most advanced ATS technology in the world. This kind of transfer switch and intelligent display mated with it are mainly applied in the occasions required uninterrupted power supply like building, posts and telecommunications, mine industry, shipping industry. Under the necessary trend of urban power service increasing, it can meet the higher requirements of the reliable power service. This product has many features like reliable performance, small volume and simple operating etc.
2.Main function
With safe and reliable interlocking function, when the breaker is under closing state, the breaker cannot be glugged in or drawn out, you must open the breaker first to plug in or pull out. With function of reliable making and breaking main circuit and secondary circuit, besides, the device possesses self-locking function. When you draw out the breaker, the device has safe insulating isolation (your finger will not touch with the charged parts). The breaker can be mounted with various rotating manual operating mechanism and motor operating mechanism.
3.Product Classfication:
Two Sections without double-break Position.
Three Sections with intermediate double-break position.
4.Conversion mode: Power on the grid, grid generator,auto-charge & auto-recovery, auto charge & non auto-recovery, and mutual standby.
