Yes, but the handles should be linked together so if only one breaker trips (phase to ground short) it will kill both poles of the circuit.

Can double pole circuit breakers be changed into single to create more room in the pannel box?
Yes. The double pole breaker can be removed and replaced with two single pole breakers. The double pole breakers are only used for 240 volt supply loads.
Why does my heating and air conditioner in my house have 3 double pole breakers - a 30 40 and 50?
In North America a two pole breaker usually represents a load that requires a 240 volt source. Larger current load appliances use 240 volts to reduce the feeder size and there by reduces the cost factor when wiring a building. Two pole 15 amp breakers are used for kitchen counter split receptacles.Two pole 20 amp breakers can be used for baseboard heating and hot water tanks.Two pole 30 amp breakers can be used for clothes dryers and some heating units.Two pole 40 amp breakers can be used for electric ranges.Two pole 50 amp breakers are not common in home wiring circuits. It might be used for an electric furnace or some other high current device.
What is 4 pole circuit breaker?
I have never seen a four pole circuit breaker. Breakers are single, two and three pole. Single pole for 120 volts, two pole for 240 volts and three pole for three phase loads. In North America all neutrals are SN (solid neutrals) and are not switched. In certain applications using a three phase Y-connected load, where complete isolation of the load from the supply is required, the neutral line connects to one pole of a 4 pole circuit breaker.
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 many wires are used for a 460 volt circuit breaker?
If the load is single phase and the load requires 460 volts to operate, then two conductors will be needed and they will connect to a two pole breaker. If the load is three phase and the load requires 460 volts to operate, then three conductors will be needed and they will connected to a three pole breaker. The sizing of the wires will depend upon the current that is drawn by the loads.

How can I connect a single-phase - 2 hot wires plus ground- 220V load to a 3-pole 220V breaker?
Common usage of a three pole breaker is for use on a three phase distribution panel. Single phase distribution panels only use two pole breakers for a 240 volt load.Remember that the breaker must protect the conductors that connect to the load. If you want to try and use a three pole breaker in a single phase panel just because you have the breaker, this is not a good idea even if it will fit.Purchase the proper single phase two pole breaker to match the wire size and the amperage of the connected 240 volt load. Keep in mind that connected 240 volt motor loads have to be sized to 250% of the motor's full load amperage.By doing what you want to do and a fault occurs from this type of installation your insurance company might not cover the damage that it would cause.If the distribution panel is three phase then just connect the two load wires to any two of the three poles on the breaker.
Why would a dryer in Canada run off of 2 single pole 15 A breakers without tripping and dry clothes perfectly?
My mistake. They are single pole 30 amp breakers. Probably should replace with a double pole. Sorry for any incovenience to this forum. d

3 pole circuit breakers?
3 pole circuit breakers are used for 3 phase lines
What difference between using 4poles circuit breaker and using 3 single pole breakers?
3 pole would be for 3 phase, 4 pole would be 3 phase & neutral

What does it mean when you have two 30 amp breakers linked together?
Two single-pole 30 amp breakers tied together make a two-pole 30 amp breaker. From this you can power a device that requires 220-240 volts, typically.
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.
What is the difference between single pole mcb and double pole mcb?
A single pole circuit breaker can protect one hot wire to a given load where as a two pole circuit breaker can protect two hot wires to a given load. In the North American system this would equate to 120 volts on a single pole circuit breaker and 240 volts on a two pole circuit breaker.
