These snap action single operation thermal protectors operate as a high limit, single operation (non-resettable) type control. These unique single operation bimetallic thermal control devices have a phenolic resin case with isolates them from the electrical circuit. As single operation thermostats, they perform like a thermal fuse with the reliability of a 100% tested bimetallic thermal control.
Features
- 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.
