Thermostats - Mechanical

This Product Selection Guide contains information to help select products in the Thermostats - Mechanical category on DigiKey.com

Mechanical Thermostats are designed to keep components safe in situations where there is an excessive amount of temperature. Components in this family will open or close a circuit that they are installed in when the Switching temperature (Adjustable, 14°F to 500°F) of the device is exceeded. The Reset temperature ranges are Manual Reset, One Shot, and 20°F to 440°F with Current ratings of 0.045 A to 25 A.


SelectionCharacteristics

Circuit: Describes the way the device actuates.

Switching Temperature: The nominal temperature at which a device’s output changes state. Actual temperature switch points are subject to manufacturing tolerances and hysteresis effects.

Reset Temperature: The temperature at which an actuated thermostat is rated to return to its resting (low-temperature) state.

Current Rating - AC: The maximum AC current the device is rated to interrupt, under the manufacturer’s stated test conditions.

Current Rating - DC: The maximum DC current the device is rated to interrupt, under the manufacturer’s stated test conditions.

Tolerance: Characterizes the extent of permitted variability of overall device temperature measurement among samples of a given part number, resulting from variations in manufacturing.

Switching Cycles: The number of actuation cycles at rated current that a device is expected to withstand.

Termination Style: Describes the shape or standard configuration of a device’s electrical connection(s).

Mounting Type: Indicates how the device is attached.

Package / Case: Describes the footprint and type of body the item has based on a general standard.
