Hermetic Compressor and protects Motor by cutting off
current in Compressor Motor by Bimetal in the OLP in
case of over-rising temperature.

(2) When over-voltage flows to Compressor motor, Bimetal

works by heating the heater inside OLP, 
and OLP protects Motor by cutting off current which
flows to Compressor Motor.
