Latest company news about Type selection operating guide for electronic centrifugal switch


First of all, we need to know whether the voltage is 220V or 110V.


Secondly, whether it is a double voltage motor or not. Generally, a double voltage motor selects the product of 110V.


Next, the current Ics of the motor for starting is measured (see figure)

electronic centrifugal switch


According to the connection of the above figure, the power is set to the rated voltage, the motor is blocked and electrified, and the Isc displayed on the ammeter is recorded. And then, the type selection is conducted in the selection table based on the recorded Isc.


(Pay attention to the selection of power and voltage)  (Single capacitor, namely YC motor, neglects motion capacitance)

110V 1100-2000W REES-140P 85-135VAC 50/60HZ
220V 0-550W REES-205P 160-260VAC 50/60HZ
220V 600-2000W REES-220P 160-260VAC 50/60HZ
220V 2200-4300W REES-2240P 160-260VAC 50/60HZ


The above electronic centrifugal switches are applicable for the YC, YL series of the motor, without distinction between the poles 2,4,6,8 of the motor.
