Explanation of the motor code

In consideration of the varoius power supply systems Bitzer offers motors with different operating voltages and frequencies for all compressors. In the following tables the available operating voltages for the specific compressors are listed. To identify the operating voltages and the motor connection, Bitzer adds the motor code to the compressor name.

Orbit series

Example

For the motor code 4 the following table shows the different motor connections for the respective operating voltages and frequencies:

• 380-420 V / 3 / 50 Hz / Y
• 440-480 V / 3 / 60 Hz / Y

Voltage range (V)	Nominal voltage (V)	Motor code	Motor connection	Nominal voltage (V)	Voltage range (V)
50 Hz				60 Hz
380-420	400	4	Y	460	440-480

ESH7, ELH7 and ELA7 series

Example

For the motor code 40S the following table shows the different motor connections for the respective operating voltages and frequencies:

• 380-420 V / 3 / 50 Hz / Y
• 440-480 V / 3 / 60 Hz / Y

Voltage range (V)	Nominal voltage (V)	Motor code	Motor connection	Nominal voltage (V)	Voltage range (V)
50 Hz				60 Hz
380-420	400	40S	Y	460	440-480
