Information 310e Thermal Protector types N01, NK1 and N02 (for Printed Circuit Board Application) Application: The Thermal Protector (TP) Type N01/NK1 (NC) and Type N02 (NO) with connection pins are specifically designed for direct installation into printed circuit boards for overheating protection of heat sensitive electronic components and circuits. φ 10 The Thermal Protector N01/NK1 and N02 are based on the well-proven mechanism of Thermik’s product series 01 and 02, featuring two solid, non insulated connection wires either with vertical or horizontal take off. A high temperature resistant insulation cap insulates the protector on the terminal side and provides the required distance between the connection wires. The protectors heat sensitive side with the marking on it is not insulated (caution: on voltage potential) for better heat sensitivity. Operation: When the temperature has reached the factory preset value, the bimetallic disc activates the snap-action disc, which in turn opens the contact (N01/NK1) or closes the contact (N02). Only after a significant temperature drop, the bimetallic disc resets and causes the contacts to reclose (N01/NK1) or to reopen (N02). Features: Small design Quick response sensitivity High pressure stability Vibration-proof Very short bounce times Closed metal housing Excellent long term performance : to fit closely built-up circuits : featured by small protector mass and by the metal housing with non insulated heat sensitive side : due to metal housing and steel cover : up to 100 m/s2 at 10 – 60 Hz in all directions : < 1 ms : suitable for impregnation : reproducible switching temperature values due to the tempered, electrically and mechanically unstressed bimetallic disc. Constant contact pressure due to the snap action disc over the whole temperature range. Instantaneous switching for a minimal strain of the fine silver contacts
