Information 405 e Thermal Protectors Series 01 Types C01 / CK1 / C02 / S01 / SK1 / S02 Application: Thermal Protectors of Series 01 - Types 01 / K1 (NC) and 02 (NO) are utilised for overheating protection of all kinds of electrical equipment or devices, most suitable for electrical motors whereat after overheating and subsequent cooling an automatic resetting is required. Conditionally by the high pressure stability of the housing, they can either be attached on or embedded within coil windings. CK1 and SK1 are the preferred types for low switching temperatures. Design: These switches are equipped with a high capacity contact mechanism, wherein the bimetallic disc can move freely, without the current flowing through it. An additional spring disc maintains constant contact pressure until reaching its switching temperature. Versions: S01 / SK1 / S02 with insulation cap C01 / CK1 / C02 without insulation cap Operation: If, in the case of overheating, the rated switching temperature of the bimetallic disc is reached, it suddenly snaps over and opens (01 / K1) or closes (C02 / S02) the contact. After cooling down beyond its resetting temperature, the bimetallic disc returns automatically to its initial position. Diameter d (with / without insulation cap) Height h (with / without insulation cap) Length of insulation cap l 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
