10. ELECTRICAL SPECIFICATIONS
10.1 MOTOR TYPES
Each compressor model has specific electrical components, indicated
in the compressor Technical Datasheet in
Embraco Product Selector on
www.embraco.com
Avoid usage of different components.
CSR (CSCR) (Capacitive Start & Run - Capacitor Start Capacitor Run)
This motor has a start capacitor and a run capacitor. The start capacitor is connected in parallel with the run
capacitor during the compressor start-up and it is disconnected by a starting relay (voltage type) at the end of
the starting; the run capacitor is permanently connected in series with the start winding. Both running and start
windings remain connected even after the motor starts.
3Ø (Three-phase)
Three-phase winding with star connections, this motor doesn’t need a starting device.
Operation of motor-compressor at different rated voltage than assigned (marked on
the label) may result in improper function of motor-compressor, missing actuation of
overload protection or even to damage or motor-compressor and/or its accessories.
It is allowed compressor operation within Voltage working range indicated in
below Table:
