Thermal Switches and Thermal Protectors from Portage Electric Products, Inc.
Single Operation Bimetallic Thermal Control -- H-7




These Snap Action Thermostats operate as a high limit, single operation (non-resettable) type control. The ceramic case isolates them from the electrical circuit and allows them to operate at temperatures up to 260°C. As single operation thermostates 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 devices. 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.
- Ceramic case isolates devices from the electrical circuit and is suitable for use in high temperature applications.
- Can be mounted 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.
