2Y-△ connection two-speed motor contactor control circuit three
Source: InternetPublisher:子丑寅卯 Keywords: Control circuit motor contactor control Updated: 2020/03/06
The circuit is shown in Figure 3-98. The low-speed start and high-speed operation of the motor are controlled by the transfer switch SA .
Adjusting the time relay KT can change the time interval between starting the motor at low speed and running at high speed.
