These snap action single operation thermal protectors operate as a high limit, single operation (non-resettable) type control. Ultra fast thermal repsonse due to the unique position of the bimetal element. As single operation thermostats, they perform like a thermal fuse with the reliability of a 100% tested bimetallic thermal control.
•Snap action devices; quick make/quick break switching action.
•Single Operation type thermostats. Reset temperature is less than -35°C. This prevents the thermostat from resetting under normal operating conditions.
•Unique positioning of the bi-metallic element allows for excellent heat transfer for improved reaction time.
•Available with exposed bi-metallic elements for even faster thermal response.
•Phenolic resin case isolates devices from the electrical circuit and is suitable for use in high temperature applications.
•Can be moounted directly on a heated surface.
•Preset calibration temperature, not adjustable in the field.
•Opposite end termination allows for flexibility of installation.
•Factory installed lead wires or terminals available – Consult Factory.
