It is a residential circuit breaker to increase your circuit boards power. They are no longer widely available but they can be purchased from eBay and other on-line retailers.
no, not a fire hazard if it works don't fix it I have never cared for pushmatic breakers, but they work ok
The purpose of a circuit breaker is to protect electrical circuits from short circuiting.
The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.
only if listed in the panel board

The purpose of a circuit breaker is to protect electrical circuits from short circuiting.
The job of a breaker is to limit the amount of current that is applied to the size of wire that is connected to the breaker.
Usually a 15 or 20 amp breaker is sufficient
the purpose of a vacuum breaker is to keep the dirty water that might be in the sink from syphining back through the sprayer hose and going into the public water system.

There are various to check if your air circuit breaker working. You can use various tools that are available to test your air circuit breaker. A clamping ammeter is ideal for this purpose.
A circuit breaker is designed so that it will trip when the electric current is too high. That is the purpose of a circuit breaker. If there is a metal piece on the circuit breaker that prevents it from tripping, it is useless. Perhaps someone has altered it.
If i understand you correctly, yes there certainly can be. If you replace, say a 10 amp breaker with a 20 amp. you are losing the safety factor - the whole purpose of the breaker to begin with. Always replace a breaker with the exact same amperage rating!
A siphon breaker works in big closed tanks by transferring fluid to an upper level coming into a tank from above. The purpose of the siphon breaker is to produce pressure at its outlet and the fluid weight to produce pressure.
