It provides power to 3 conductors simultaneously, and more importantly, disconnects all three conductors simultaneously in case of a fault. A three pole breaker is used with a three phase power system.

Rating of a 3 pole circuit breaker is the same for each conductor?

Yes, the rating of a 3 pole circuit breaker is the same for each conductor that is connected to it. A three pole breaker rated at 30 amps will have 3 #10 wires from it that connect to the load.

Can a 220 VAC breaker be single pole or does it have to always be a double pole breaker?

U.S. 240 VAC breakers are always double pole since they are protecting two legs of the circuit.


How do you define a pole in circuit breaker?

A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time


Can you use a 2 pole breaker for a 120 volt single phase circuit?

A single phase circuit uses a 2 pole breaker if the circuit is 120/240 split phase and the load is connected 240. Both legs are hot, so both need to be protected. This is the normal US/Canada configuration.


Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?

Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.

Can a double pole 20 amp breaker be used with 12-2 wire for a single 220 circuit?

The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
