OLP (OVER LOAD PROTECTOR)

7.3.1

Definition of OLP

i.

OLP (Over Load Protector) is attached

to hermetic Compressor and protects

motor by cutting off current in

Compressor motor by Bimetal in the

OLP in case of overrising temperature.

ii.

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.

7.3.2

Role of OLP

i.

OLP is attached to hermetic

Compressor used to refrigerator and

show case and prevents motor coil

from being started in the Compressor.

iii. Do not turn the Adjust Screw of OLP

in any way for normal operation of

OLP (Composition and Connection
