Klixon SL-11 kits are mounted on the windings of general purpose motors and hermetically sealed compressors. They supplement conventional current overload relays in magnetic starters providing modern total protection for most older motors in use today. In addition to being small and lightweight, the unit is both temperature and current sensitive. Since the 9700 is sealed to withstand varnish dipping, it can be mounted directly in windings where it can best sense the true temperature of the electrical equipment. As a result, over-temperature protection is assured. Since the case is not electrically insulated, the protector is furnished with a durable Mylar insulating sleeve. - Klixon® thermostats provide a normal contact which opens within ±5°C of its rated catalog temperature. It recloses 20°C below its opening temperature. We stock 120°C and 130°C ratings to provide protection for Class F and Explosion proof motors. The 120°C rating is usually safe for all applications with Class F insulation. The 130°C rating allows more load and fewer nuisance trips.
