Single phase motor
protection and suggested
wiring diagram
Single phase compressor motors are internally
protected by a temperature / current-sensing
bimetallic protector which senses the main and
start winding current as well as motor winding
temperature. If the motor were to be overloaded
and the protector trips, it might take up to several
hours to reset and restart the compressor.
The standard CSR wiring system provides addi-
tional motor torque at start-up, by the use of a
start capacitor in combination with a run capac-
itor. The start capacitor is only connected during
the starting operation and a potential relay
disconnects it after the start sequence. This sytem
can be used for refrigerant circuits with capillary
tubes or expansion valves.
