Please call an electrician before you burn your house down! Changing a 40A breaker to a 50A breaker will eventually melt your wire's insulation and start a fire if it continues to trip. I would say you should change it back, but you should let the electrician do that. There is a short or overload in that circuit, which needs to be corrected before you attempt to reapply power. Circuit breakers are not there to make your life harder, they are there to make your life longer! Have a professional electrician correct the short or overload and then replace the breaker with a properly rated breaker before energizing the A/C unit.
The electrical terminology for this type of breaker is a tandem breaker. It is where two breakers circuits can be in the same one breaker slot in a distribution panel. On this type of breaker there will be two output for a circuit value of what ever the breaker is rated for.
Circuit breakers operate on current not voltage.
Tandem breakers, often called split breakers or double breakers, provide two separate circuits in the space of a regular sized breaker opening. Every circuit breaker panel has a limited number of circuit openings available. The problem is that when the openings are all used up and you still need to add another circuit, what do you do? You could change the electrical panel or double up circuits on a breaker, but this could place too much load on a particular circuit. So what then? The answer that many have found is a tandem breaker. This type breaker is the same size as any other breaker, but it has its difference. This breaker sports two smaller breakers built into one regular sized breaker. Each has its own breaker switch and the breaker snaps in just like a regular breaker. With this simple innovation, you can add a circuit and protect the circuit on its own dedicated line.
No tandem breakers are of the same value.
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.
circuit breakers are connected in series manner in the circuit.
Yes. In most cases, yes. If the circuit breaker continues to trip when there is no fault in the circuit, it may be failing and need to be replaced.

Most automotive circuit breakers reset themselves after they cool off. Some bigger trucks use circuit breakers that are reset manually. They have a button you push in to reset the breaker after it has cooled off.
Square D circuit breakers can be purchased from various homeware and DIY stores such as Home Depot or Lowes. Websites that specialise in circuit breakers such as Circuit Breaker Service or All Breakers do sell them as well.

AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
