A circuit breaker does not "cause" smoke. A circuit breaker "breaks" a circuit when there is too much current, creating a hazardous condition for the wires that are connected to the circuit breaker.
The circuit breaker PROTECTS you from electrical fire.
Find the source of the smoke; what burned?
If a circuit breaker tripped during the incident, it is usually caused by melting/burning wire insulation, either inside or outside of an appliance. If the insulation inside the walls of your house has burned/melted, it could be that the circuit breaker was too large for the wire or that the circuit breaker failed to shut off at the appropriate current load.
If the circuit breaker failed, your insurance should help you.
If an appliance overloaded the circuit, your insurance should help you.
If someone connected an oversized circuit breaker, causing the wire to overheat, your insurance company may refuse to help you.

Homeowner insurance typically covers damages caused by a circuit breaker trip, including any resulting smoke damage, as long as the damage was not intentional or due to negligence. It is important to review your specific policy coverage and consult with your insurance provider for more information.
A circuit breaker switch could spark due to a buildup of heat or a high level of current flowing through it. This can lead to arcing between the contacts inside the breaker, resulting in sparking. Additionally, loose connections or damage to the breaker can also cause sparking.
A short periodic low hum from a circuit breaker could indicate loose connections within the breaker or surrounding wiring, internal mechanical issues within the breaker itself, or electromagnetic interference affecting the breaker. It's recommended to have a qualified electrician inspect the breaker to determine the exact cause and address any potential safety hazards.
If your smoke detector is bleeping you have a serious risk of fire and the circuit breaker must not be reset until the fault that caused it to trip is investigated.
A short circuit in an oven can cause the circuit to overload, leading to a sudden surge in electrical current. This can potentially damage the oven components, trip the circuit breaker or fuse, or even cause a fire. It is important to address the short circuit promptly to prevent any further damage or safety hazards.
A breaker trips when its rated current has either been slightly exceeded over a period of time or grossly exceeded instantaneously.
