Motor Temperature Overload Protection Bimetal Thermal Switch Thermostat 7AM Thermal Protector

General Description: The 7AM Thermal Protector is the market leader, backed by proven innovations in protection technology. The 7AM is a thermally operated snap-action device which delivers the maximum protection in the smallest package at an affordable price. The 7AM is a proven performer in protection technology with over 35 years of design experience combined with a modern state-of-the-art manufacturing facility.

Operation: The operating principle of the 7AM is both simple and effective. At the heart of the protector is a bimetal snap-action disc. When the
temperature of this disc reaches its pre-calibrated 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 current flowing through the disc, or a combination of both. After the 7AM breaks the circuit, the system cools and the 7AM automatically resets allowing power to be restored to the circuit.

Quality: Each 7AM 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 to achieve consistent, reliable performance over the required life cycle. This high level of performance is obtained through Texas Instruments' traditional emphasis on quality. A
corporate-wide thrust, re-emphasizes the supplier's responsibility and integrates modern statistical techniques into the production and quality
assurance processes. As continuous inputs to the quality monitoring systems, more than twelve different checks are made during the
manufacturing process.
