This high quality, Chinese manufactured unit is also called a transfer load switch. It is suitable for the shift of two-way power and provides safe isolation. The YGLZ series meets the IEC60947-3 and GB14048.3 standards. The small size and compact design makes for easy installation of the unit by a qualified electrician. The unit is extremely affordable and will provide many years service when correctly fitted. The unit is operated by means of a handle which is installed on the switch. If the unit is fitted inside a distribution cabinet the handle can be fitted on the outside of the cabinet and an observation window will allow the user to view the status of the switch. The YGLZ series ranges from 125 Amps up to 3150 Amps.
Benefits of the YGLZ-400 3-POLE 400AMP Manual Transfer Switch
The transfer switch plays an essential role in keeping critical electrical load functioning during power outages. Most large factories as well as hospitals and data centres and many other commercial and institutional facilities require a constant supply of power. When the mains power fails they need to have a backup power source like a generator. Transfer switches are a means of quickly and safely transitioning all critical electric circuits from one power source to the other. With a manual transfer switch the generator needs to be switched on and running correctly before the transfer is made.
Characteristics of the YGLZ-400 3-POLE 400AMP Manual Transfer Switch
The switching mechanism is the part of the transfer switch that is physically responsible for carrying the rated electrical current and shifting the connection between the power sources. The unit will isolate the one power source before allowing the other to enter the system. This is a safety measure to prevent any power flowing back down the power lines. This safeguards the repairmen who will be working to restore power and who could be electrocuted by feedback from a second source. The unit is simple to operate even by a relatively inexperienced person.
