7AM Series Thermal Protectors Bi-metal Protector

The 7AM thermal protector prevents overheating in a variety of consumer, industrial and commercial products. It is a miniature, snap-acting, thermally operated device that is a proven performer in protection technology. We can provide these units with a variety of leads, terminations and insulating sleeves to meet specific require- ments.

How the 7AM protects against overheating

Current flows through your lead connection into the can crimp terminal, through the can member, bimetal disc, and mating contacts. The current completes its path by exiting through the plate member and the integral plate crimp terminal to your lead connection.

As the temperature rises, the heat is transferred to the bimetal disc. The disc then snaps open at the factory-calibrated opening temperature, thus breaking the current path.

The bimetal disc snaps closed when the reset temperature level is achieved.
