Refrigeration Parts #1191844

DEFINITION OF TERMSAutomatic Reset: A type of thermostat that will automatically reset at a specific temperature (i.e. a thermostat operates at65, 5 oC [150 oF] and resets at 48, 89 oC [120 oF]).Bimetal: Two dissimilar metals bonded together to form the material for manufacturing thermally-sensitive discs which actuatethe thermostat.Close on Rise (COR): Refers to operation of the contacts. When the temperature rises to its set point, the contacts close ormake 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 apredetermined overvoltage for a specified time.Differential: The temperature difference between the operate and reset set points, also known as operate and reset.- 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.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 voltageand 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 fullvoltage 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.
NOTESStandard Temperature Characteristics Tables:- 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 shouldbe made to establish the widest acceptable tolerance possible.UL and CSA Approvals: 12, 7 mm [0.5 in] thermostats are available with multiple agency approval for incorporation intoequipment.Fan control applications: Require thermostat set points to be derated by 20 C from the equivalent temperature limitapplication. They also close on rise.Dimensions: Are for reference only and are given in mm [in].
