Double Pole Breaker Symbol

Such kind of breakers is used in three phase systems in industries.

Double pole breaker symbol.

This switch can be wired up as a reversing switch for a motor. A dual on off switch which is often used to switch mains electricity because it can isolate both the live and neutral connections. A dual on off switch which is often used to switch mains electricity because it can isolate both the live and neutral connections. Double pole double throw.

That means if there s a short circuit on either of the poles hot wires both trip. It connects three phases whenever there is an overload or short circuit in any phase the circuit breaker trips all three phases simultaneously. It cannot be used to supply 240 volts to a single circuit. After selecting the spdt symbol you can change the switch position up center or download by the action button.

Unlike a double pole breaker which serves a single 240 volt circuit a cheater serves two 120 volt circuits.

The voltage from either leg to the neutral line is 120 volts but across the two hot legs is 240 volts which is double the 120 volt supply.
