switch 16 by the switch operation piece 26, the cut-off mechanism 32 is operated to turn off the electric circuit in the circuit breaker 1, and the abnormal notification part 33 is operated to inform the circumference that the connection state of the electric wire 50 is abnormal.Diagram...
A circuit breaker system designed for three-phase, four-wire, delta- connected electric panelboards or loadcenters allows users to derive 120 volts from vacant full size higher voltage leg bus spaces. Two independently operating circuit breakers arranged side by side, in a side-car configuration,...
The diagram below shows the simplified version of a self resetting circuit breaker. In this device, the current flows from the battery terminal, through the bi-metal strip and then to the other terminal. The bi-metal strip is made of two different types of metal which have different coefficie...
