Information 411 e Thermal Protectors Series 06 Types L06 / L08 Application: Thermal Protectors (TP) of series 06 - type L06 with normally closed contacts are utilised for overheating protection of all kinds of electric equipment or devices. After over-heating and subsequent cooling an automatic resetting is required. The type L08 with normally open contacts is utilised to start fans, warning lamps or acoustic signals in case of overheating. A mount-on housing allows to attach these types e.g. in switch cupboards, on heat sinks or on motor casings. Design: These switches are equipped with a high power 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. The well-proven mechanism of Thermik’s types 06 and 08 are introduced into a housing with an M4-screw including an internal insulation between the switch and this screw-housing. The connecting lead wires are welded on, to ensure the use the switch at high temperature and strong currents without any problems. Screw / -length dimensions (average) Operation: If, in the case of overheating, the rated switching temperature of the bimetallic disc is reached, it suddenly snaps over to open the contact of type L06 or to close the contact of type L08. After cooling down beyond their resetting temperature, the bimetallic disc resets and causes the contact to reclose (type L06) or to re-open (type L08). . Features: Small dimensions : to fit closely built-up circuits : featured by small protector mass and excellent heat Quick response sensitivity transfer from the metal-housing to the bimetallic disc Excellent long term performance : due to instantaneous switching, fine-silver contacts, constant contact resistance and to electrically as well as mechanically unstressed bimetallic disc, reproducible switching temperature values : < 1 ms Very short bouncing times Instantaneous switching : with constant contact pressure over the whole temperature range Temperature resistance : by use of high temperature resistant materials and components
