TH3838A - Double coil electromagnetic induction machine used in circuit breaker circuits. - Google Patents

Abstract

Electromagnetic induction machine consisting of an outer coil and an inner coil. The outer coil induces electromagnetic when using a predetermined overload and the inner coil induces electromagnetic when an internal earth leakage occurs. Power supply circuit By the aforementioned electromagnetic inductor where the outer winding is connected in series to the distribution circuit and the said inner coil in series with the balanced winding transformer. Where the electromagnetic induction of the two windings Will pull the electrical contacts of the circuit breaker switch to open the electrical circuit. To cut off the power supply inside the circuit breaker

Claims (3)
