•
Automatic Reset: A type of thermostat that will automatically reset at a specific temperature (i.e. a thermostat operates at
65,5
Bimetal: Two dissimilar metals bonded together to form the material for manufacturing thermally-sensitive discs which actuate
the thermostat.
Close on Rise (COR): Refers to operation of the contacts. When the temperature rises to its set point, the contacts close or
make contact and complete the circuit.
Contact Resistance: The value of resistance measured between the terminals.
Dielectric Strength: The value of insulation between two electrically conducting parts. It may be tested by the application of a
predetermined overvoltage for a specified time.
Differential: The temperature difference between the operate and reset set points, also known as operate and reset.

Exposure Temperature: Thermal environment of a device during application operation.
FLA (Full Load Amps): Current taken from the line by the motor when the motor is yielding the rated hp at the rated voltage
and frequency.
Life Cycles: The endurance rating of the thermostat expressed in number of operations with stated electrical load applied.
Temperature limit application = open on rise.
LRA (Locked Rotor Amps): The amount of current the motor can be expected to draw under starting conditions when full
voltage is applied, also known as starting inrush current.
Manual Reset: A bimetal thermostat with a reset button that must be pressed to reset the contacts.
Open on Rise (OOR): Refers to the operation of contacts. When the temperature rises to its set point the contacts open,
terminating the circuit.
Overmold: Encapsulation with an insulating material.
Phenolic: Thermoset plastic used for the insulating body of the thermostat.
Set Point: The nominal temperature at which the thermostat operates.
SPST (Single Pole/Single Throw): A switch with one current path which can be either open or closed.
Tolerance: The allowable range above and below the set point temperature.
Operate: Change of state when the thermostat reaches its set point.
Reset: Change of state when the thermostat returns to its original condition prior to operation.

UL and CSA Approvals: 12,7 mm [0.5 in] thermostats are available with multiple agency approval for incorporation into
equipment.
Fan control applications: Require thermostat set points to be derated by 20 °C from the equivalent temperature limit
application. They also close on rise.
Dimensions: Are for reference only and are given in mm [in].
Nominal: The temperature difference between nominal set points regardless of tolerance.
Maximum: Maximum number of degrees between actual opening and closing set points.
Minimum: Minimum number of degrees between actual opening and closing set points.
Temperatures: Please consult applications engineering for temperature ranges, tolerances and differentials not noted.
The operating temperature ranges include tolerances.
Tolerances: The ± tolerances given have been established after review of many thermostat applications. Attempts should
be made to establish the widest acceptable tolerance possible.
