Feature 1

One shot type thermostat developed on the basis of the CS-7. It can function only once and will no longer be reset after functioned, same as a thermal cut-off.

Feature 2

Operating temperature can be arbitrarily set, in contrary with conventional thermal cut-off that has only limited operating temperature. It is excellent in aging deterioration in high temperature atmosphere compared with conventional thermal cut-off.

Feature 3

Contact type that is used in direct contact with a heat source and Non-contact type that is used with a clearance from a heat source are available with excellent thermal response.

Feature 4

The specifications of the temperature range and the terminals are subject to limitations under the safety standards.
