Abstract

384,597. Automatic circuit-breakers. LEYHAUSEN, W., 79, Bucherstrasse, Nuremberg, Germany. July 1, 1932, No. 18636. [Class 38 (v).] In order to reduce the cross section of wire in the magnet windings of small circuit-breakers, and to enable a small thermal element to be used, the winding is divided into two parallel-connected parts c, d and the thermal element t or its heating coil is connected in series with one part. The parts c, d may have different numbers of turns so as to adapt the thermal element to a particular current value, or coils with different gauges of wire may be employed for this purpose.
