If the load is continuous you need to observe 80% rule. A 20 Amp breaker will handle short term loads that exceed 16 Amps. Think about it as a heat issue where continuous higher current will heat up components to unacceptable levels.
For a 41 amp load, you would typically use a 50 amp circuit breaker. The general rule is to select a breaker size that is 125% of the continuous load amps or equal to the load amps if it is not a continuous load. In this case, 41 amps is considered a continuous load, so you would round up to the nearest available breaker size, which is 50 amps.
The equation for amperage is Amps = Watts/Volts = 10000/240 = 41.6 amps. It is not stated if this is a motor load or not. If it is a motor load then the feeder has to be rated at 125% x 41.6 = 52 amp wire. Also if it is a motor load then the breaker will have to be 250% x 41.6 = 104 amps. A 100 amp breaker will work and still be within the electrical code ruling. Otherwise for 41.6 amps a 50 amp breaker will be sufficient.
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
No, a 12-gauge wire is typically rated for a 20 amp circuit. To safely handle a 25 amp breaker, you would need to use a 10-gauge wire. It's important to match the wire gauge to the amperage rating of the breaker to prevent overheating and potential fire hazards.

The maximum amperage capacity of a 240 amp breaker is 240 amps.
The maximum current capacity of a 120 amp breaker is 120 amps.
The maximum current capacity of a 225 amp breaker is 225 amps.
The maximum amperage capacity of a 30 amp breaker is 30 amps.
The maximum current capacity of a 125 amp breaker is 125 amps.
The maximum current capacity of a 150 amp breaker is 150 amps.
The maximum current capacity of a 90 amp breaker is 90 amps.
The recommended amperage for a 30 amp RV breaker is 30 amps.
I would suggest a 20 amp breaker. * Added - I would suggest a 25 amp breaker. A slight surge, depending upon what equipment is the source of the 17.3 amp load, should not result in circuit breaker opening. <<>> In North America, the electrical code only allows circuit loading up to 80% on a continuous load. A 20 amp breaker can be legally loaded to 16 amps. A 25 amp breaker can be legally loaded to 20 amps.

15 amp breaker.
