If your furnace is 20 kW unit, the maximum amperage it can draw is 83 amps at 240 volts. If it is a two stage unit the first element will be the 5 kW and the second element sill be the 15 kW element. If you are connecting the unit to a 60 amp breaker it will only allow either the 5 or the 15 kW element on but not both.
The breaker in the unit needs a voltage source brought to it from the service distribution. If this is a new installation, call an electrician as permits should be taken out for your protection. By doing this, if a fault occurs and a fire is started the first thing that the insurance company wants to know is if the installation was inspected. If you have no documentation you might not be covered.
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.
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.
For 220v circuits
The provisioning of the breakers in a panel has a physical limitation regarding how many breakers will fit and a load calculation based on what devices the panel has to support. Your question really applies to both types of breakers. There are rules of thumb for sizing and populating the panel. This information is in the National Electric Code. If you have an existing panel and a new application requiring additional breakers for 220 Volt applications, the current draw in panel can be measured by an electrician and you will know what additional load you can support. If breakers fit physically in the panel, but connected devices exceed the total current capacity you will trip the main panel breaker. At this point you would need to get an electrician involved.
GE circuit breakers with catalog numbers ranging from THQL1115 through to THQL1150 can be substituted like for like with Cutler-Hammer circuit breakers coded CL115 through to CL150, ITE Siemens circuit breakers coded Q115 through to Q150 and Square D circuit breakers coded HOM115 through to HOM150. These are single pole breakers. GE circuit breakers with catalog codes from THQL2115 through to THQL2150 can be substituted with Cutler-Hammer circuit breakers CL215 through to CL250, Square D circuit breakers HOM215 through to HOM250 and ITE Siemens circuit breakers Q215 through to Q250 of the same amperage and voltage. These are double pole breakers.
Normally creatures break a single shield but double breakers break two sheilds.Similarly with triple breakers

Most of the breakers in a panel will be 120 VAC. Double height breakers are 240 VAC. A triple height breaker probably indicates you have 3-phase power in the panel.
240V appliances, such as range, dryer, air conditioner.
Check voltage on top side of breaker each leg to ground should read 110 if not check main fuses on incoming side to be sure 220 is present,then check secondary side of fuses 220 line to line 110 from line to ground.I think you will find that one leg is open. Did you use a 1 inch double breaker by chance.You need to use regular double pole breakers so you get volts from both phases,The skinny double breakers are the same width as a single 1 inch breaker but they are running off one phase and that would cause your problem.
U.S. 240 VAC breakers are always double pole since they are protecting two legs of the circuit.
