Thermal Protectors (TP) of version e1 with normally closed contacts are standard versions, utilised for overheating protection of all kinds of electrical equipments or devices, e. g. for electric motors, heaters and transformers. They can either be installed on or embedded inside the windings. Due to their small overall dimensions, they will fit even in smallest space. > Diameter The version e1 has an epoxy coating for best thermal transfer to the housing. Therefore when fitting ֖ the base insulation of the switch is provided and does not need to be done by the customer. The insulation is marked with the manufacturer logo, type and the nominal switching temperature with its tolerance. > d 10.1 mm Height h 4.0 mm dimensions (average) If, in case of overheating, the rated switching temperature of the bimetallic disc is reached, it suddenly snaps over to open the contacts. After cooling down to the resetting temperature, the bimetallic disc resets and causes the contacts to reclose. . > Smallest dimensions: therefore suitable for smallest applications High response sensitivity: featured by small protector mass and the metal - housing Excellent long term performance : performance of reproducible switching temperature values due to instantaneous switching, fine-silver contacts, constant contact resistance and to electrically as well as mechanically unstressed bimetallic disc Very short bouncing times: < 1 ms Instantaneous switching: with constant contact pressure over the whole temperature range Temperature resistance: by use of high temperature resistant materials and components > Thermik Gertebau GmbH ?
