Compressor Motor Winding
Thermostats
CSHD Compressors
The compressors contain an internal line break
overload which stops the compressors under a number
of operating conditions that cause excessive motor
temperature. These include rapid cycling, loss of
charge, abnormally high suction temperatures,
excessive amperage, phase loss and low voltage
CSHN Compressors
PTC sensors are embedded in the motor windings of
each Scroll compressor. These sensors are wired to the
protection module which protects the motor from over
temperature that can occur under a number of
abnormal operating conditions. These include rapid
cycling, loss of charge, abnormally high suction
temperatures, low voltage and excessive amperage.
VZH Variable Speed Compressors
Over current and over torque protection for VZH
compressors are provided by the inverter.
