best remote control circuit breaker list and get free ... Figure 2. Therefore when any one relay or switch contact closes, thus completing the circuit, the breaker trips. Only exception to the parallel wiring of contacts is the low-gas auxiliary relay contact (63X in the figure). This one is wired in series. Why?Modern power circuit breakers employ Sulfur Hexa-Flouride (SF6) gas to extinguish an arc.
