Abstract
1,049,106. Protective arrangements. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. June 15, 1964 [June 14, 1963], No. 24653/64. Heading H2K. A protective circuit for an apparatus, e.g. a motor in, includes at least one positive temperature coefficient resistor r in series with the winding of an electromagnet d which normally retains contacts 2 closed. These contacts are initially closed by the operation of a " stop " and " reset " push-button b2 which opens the stop contacts 1 when closing the contacts 2. On release of the push-button b2, the contacts 1 reclose so that the operation of start-button b1 causes a main contactor C to close. In the event of overheating of the motor windings, the resistance of the resistor r increases, causing the electromagnet d to release the contacts 2 and the contactor is opened.
