The thermal protector TB05 is normally not current sensitive. Temperature detection is realized by a bimetal snap disk. Using high-impedance bimetal material, the response time of the protector can be reduced (moderate current sensitivity). The thermal protector is available with normally closed (NC) as well as normally opened (NO) contacts. After cooling down to the snap-back temperature of the bimetal disk, the protector returns to its initial position automatically.
