For circuit breaker what does it mean by AF AT?
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.
What is a difference between 10KA and 22KA circuit breakers?
The previous answer is incorrect, and I would advise that user to not give out information if they are going to give completely misguided information. The interrupting rating of a breaker is the maximum current that the breaker is designed to handle, at the breaker's rated voltage, before damage will occur to the breaker. A breaker will trip at FAR LESS than the interrupting rating, but it is extremely dangerous to expose the breaker to any situation where it will have more than the rated interruption current. the breaker is designed for. The reason some breakers are rated at 22kA instead of 10kA is because they typically have far larger conductors hooked up to them, so with the lowered impedance on the circuit there is more of a chance for the breaker to experience a higher fault current at the breaker. So electricians install 22kA breakers to handle the higher "available fault current."
What is Ir value of a circuit breaker?
Ir is the Interrupt rating of the circuit breaker. It is the maximum amount of current the breaker can withstand without damage. In a molded case breaker's electronic trip mechanism, Ir is the continuous current rating that you select, to trip the breaker at a given overload current. Standard requirements request that the breaker trips at 2 hours with an overload of 135% and will trip as a function of I squared x time selected for higher currents.
What is the Function of circuit breaker?
The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.
What is the definition of circuit breaker?
An electrical switch which automatically shuts off when amperage get above a given value.
How many 120V circuits are in a breaker circuit box?
It depends entirely on the specific application and the rating and form factor of the box. If you add up all the amperage ratings in the box it will typically exceed the total amperage rating of the box on the theory that at any given time only a portion of the circuits are used.

Definition for time current curve?
It is the relationship between current and time on a circuit breakers opening. When the circuit breaker needs to open in given "windows" of amps and time. They should intersect on the curve to indicate proper circuit breaker functioning. The timing and current value should coincide with each other, per manufacturers specifications. Each breaker differs.

Why use an enclosed circuit breaker?
To protect the wiring from overheating and catching on fire.AnswerThe term, 'switchgear', describes a variety of switching devices including circuit breakers and isolators (disconnects).A circuit breaker is an overcurrent protection device. Overcurrents are overload currents (due to too much load for a given circuit) or short-circuit currents (due to electrical faults).
What does 30 amp mean on the electrical box?
It Means it provides or contains conductors and or Overcurrent Protection (breakers/Fuses) that have the ability of carrying 30 Amperes of Electricity. Amps/Amperes is how much electricity in Volume Flows through a given conductor or breaker every second
Can I use my old central air conditioner's circuit to power a new hot tub?
The capacity of the breaker in amperage and the size of the wire connected to the breaker of the A/C circuit must be stated along with the total load of the new hot tub. Only then can an answer be given.
