Thermal Limiting Fuse: Description and Operation
SYSTEM OPERATION
Thermal Limiter Switch
The thermal limiter switch is used to measure the compressor surface temperature. If the compressor surface temperature is excessive, the switch
will cut the battery feed voltage to the compressor clutch coil. The switch will reset itself, once the compressor surface temperature returns to
normal.
The thermal limiter switch will interrupt the battery feed to the compressor clutch coil at a temperature of about 122 to 128° C (250 to 260° F).
The switch will reset and restore the clutch coil operation at a temperature of about 104 to 116° C (220 to 240° F).
