Operating Principle

The operating principle of the ST07 is both simple and effective. At the heart of the protector is a bimetal snap actiondisc. When the temperature of this disc reaches its rated temperature it snaps open, resulting in an open circuit. This temperature is reached during a fault condition, caused by either an increase in ambient temperature, an increase in currentflowing through the disc, or a combinationof both. After the ST07 breaks the circuit, the system cools and the ST07 automatically resets allowing power to be restored to the circuit.

Quality

Each ST07 rating has a bimetal disc designed and manufactured for that specific temperature rating. Each individual device is then calibrated and checked for opening temperature. This results in precise operating characteristics necessary toachieve consistent, reliable performance over the required life cycle. This high level of performance is obtained through ourtraditional emphasis on quality.
