The numbers and letters of the transfer switch LW3-16YH3/3 can be seen as follows: LW stands for universal meaning, 3 is the design number, 16 is the conventional heating current, Y is voltage, H is the meaning of conversion, and 3 is the three-phase representative type, 3 represents three sections, the whole one represents that this universal switch is used for voltage indication to convert the phase-to-phase voltage.
What are the more important functions of the transfer switch?
(1) Leakage protection
The transfer switch can protect the device and has the function of leakage protection. Although there are many types and different structures, its protective effect remains the same.
(2) Conversion
The most important function of the changeover switch, of course, lies in its conversion. The more common transfer switches are voltage type, universal, three-phase and four-phase. Various types of wiring methods are different. Among them, the universal switch has more wiring lines and a wide range of power supply lines that can be controlled. It can realize the conversion between the voltmeter and the ammeter, and play the role of measurement and control for long-distance transmission.
