Will multiple tripping of a circuit breaker damage the circuit breaker?

You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.

Is it dangerous to have water in circuit breaker?
Yes. Water can damage the breaker and prevent it from working, or it may continue to carry current after the breaker trips.
What is function of damping relay in circuit breaker?
The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the breaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the close command is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.
What does a circuit breaker do in a circuit?
Creates an open circuit in the event that the circuit becomes overloaded. It's a protection feature, preventing melting wires, damage to electrical components, and fires.
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 Selection procedure for motor protection circuit breaker?
The selection of overload protection for motors is taken from a table in the electrical code book. It is based on the full load current rating of the motor.
Why would a circuit breaker switch spark?
the circuit breaker spark when it comes an over load, loss contact,but the probable cause is loss contact...and also the circuit breaker is going to be damage or destroyed.

Can you convert a 30 amp 120V RV receptacle into a normal 120V outlet?
You can, but your circuit will be "protected" by a 30 amp breaker. So you'll have to consider the safety issues of having wiring and appliances that can draw up to 30 amps before tripping the breaker. Will the wiring and circuity support that much current without damage? If not, then switch to a 15 or 20 amp breaker.
Is fuse a part of a circuit?
When there is a fuse, yes it is part of a circuit. The fuse is a cheap, replaceable circuit breaker to avoid damage to the circuit components.

Did i do any damage to my 30 amp dryer wire by crossing it to trip the circuit breaker accidentially?
Visually inspect the wire at the short contact point. If there is no copper loss and the wire was not reduced (big crater hole) where the contact was made you are OK. If there was copper loss then cut the wire back to where the conductor is good and reconnect the dryer. There should be no damage to the dryer if it was not turned on. The breaker tripping was doing its job of protecting the wire from the over current.

The first measure you should take to help prevent damage against electrical problems is to do what to the circuit?
Protect the circuit with an OCPD, an over current protection device, such as a circuit breaker or fuse.
How a circuit breaker increases safety?
A circuit breaker limits the amps that a circuit can carry. If the amperage draw on a circuit exceeds that limit, the circuit breaker turns off the circuit. If the current through a wire exceeds the rated amperage, the wire will overheat and eventually cause a fire, or at a minimum, destroy the wire behind inside the wall. Obviously, people don't want a house fire caused by an electrical overload, so circuit breakers are used to prevent damage and potential loss of life.

How does a vacuum circuit breaker operate?
In a vacuum breaker the moving contact and fixed contact are sealed inside a vacuum chamber. Electrons cannot flow in a vacuum, therefore as soon as the moving contact seperates from the fixed contact the arc meets an infinite resistance and is immediately extinguished. Because of this, the gap between the fixed and moving contacts when the breaker is open need only be a tiny amount.
