Information 406 e Thermal Protectors Series 01 Types L01 / LK1 / L02 Application: Thermal Protectors of Series 01 - Types L01 / LK1 (NC) and L02 (NO) are utilised for overheating protection of all kinds of electrical equipment or devices, whereat after overheating and subsequent cooling an automatic resetting is required. A mount-on housing with a M4-srew allows to attach these types e.g. in switch cupboards, on heat sinks or on motor casings. The LK1 is the preferred type for low switching temperatures. Design: The Thermal Protectors L01, LK1 and L02 are based on the well-proven mechanism of Thermik’s Types C01, CK1 and C02. These standard types are introduced into a housing with an M4-screw including an internal insulation between the switch and this housing. Operation: If, in the case of overheating, the rated switching temperature of the bimetallic disc is reached, it suddenly snaps over and opens (L01 / LK1) or closes (L02) the contact. After cooling down beyond its resetting temperature, the bimetallic disc returns automatically to its initial position. Diameter d Wrench size Height Screw / -length dimensions (average) : to fit closely built-up circuits : Featured by small protector mass and the metal-housing : due to instantaneous switching, fine silver contacts, constant contact resistance and to electrically as well as mechanically Excellent long term performance unstressed bimetallic disc, reproducible switching temperature values : with constant contact pressure over the whole temperature Instantaneous switching range Very short bounce times : < 1 ms : by use of high temperature resistant materials and components Temperature resistance Specially flat design Quick response sensitivity
