Sensata Technologies’ line of automatic and manual reset protectors phenolic protectors are
intended for ½hp to 15 hp general purpose, commercial and industrial motors. These
single–phase and three–phase protectors can be used in single and dual voltage type motors.
Klixon Motor Protectors are designed to protect against damage caused by overheating due
to locked rotor running in overload or blocked ventilation conditions including: single-phasing,
plugging duty, stalling or failure to start, heavy overloads, high ambient, and ventilation failures.
This protector consists of a molded phenolic base assembly containing three heaters and a Klixon
snap–acting thermal disc with three contacts.
The protector should be mounted in the motor so that it will receive the maximum amount of heating
from the windings, not only for running but also for stalled rotor conditions.
