The breaker will trip to the off position because of the heat caused by more amps than it is rated for. Only lightening strikes do odd things. And a loose breaker connection can arch causing limited damage to breakers.

Only under extreme circumstances, like a lightning strike to the mast head. Breakers have a current interrupting rating. For a small home distribution breaker rated at 15 amps, it has an maximum RMS symmetrical interruption of 10,000 amperes. The breaker will not blow up but it will stop the current flow up to 10,000 amps. Under normal operation the breaker will trip when it reaches its operational set point, meaning that when the load current goes beyond the breakers rating, which is found on the handle, it will disconnect the circuit load.
First, determine the current draw of the coffee roaster, then check the breaker size. Using the formula, Watts = Amps * Volts, determine if the current draw of the coffee roaster is anywhere near the maximum current draw of the breaker. For example, if the roaster is using 14 Amps, and the circuit breaker is rated at 15 amps, that doesn't give much room for anything else on the circuit. Add up all of the current of all devices on the circuit (the one that trips the breaker) and either move things around so that you don't have too much load on a single circuit, or you may need to bring in an electrician to run a new circuit. If you are ABSOLUTELY certain that your appliances are nowhere near the rating of the circuit breaker, you could have a faulty breaker, in which case, bring in an electrician to replace the breaker.
Problem with ac drawing to much current.
The current (in question) flows through both the circuit AND the circuit breaker [they are in series]. Within the circuit breaker when the current exceeds the preset limit it will open the circuit thus stopping all current flow. There are two common ways of doing this 1) magnetism - a coil pulls a switch open 2) thermal - a bimetallic strip bends away from its contacts, which opens the circuit.
Where I'm from, it's called a "circuit breaker".A circuit breaker.
circuit breaker or fuse
An overload condition is demanding more current than can be supplied. This could trip a breaker, blow a fuse or possibly destroy a device that is drawing too much current.
Yes! A socket is a part of a circuit. Usually there are a number of sockets and lights associated with a specific circuit. The wiring of the circuit and the circuit breaker are limited to a specific amperage. If you exceed the amperage, you can blow the breaker. If the wire is rated for 15 amps and the circuit breaker is rated for 20 amps, the wires can overheat and cause fires.
Not necessarily. It can blow because the circuit was overloaded and pulling too much current. That would cause the fuse to overheat and blow.
A fuse blows when the circuit is drawing too much current. It could be a short or an overload.
The current is limited by the fuse or circuit breaker.

Either a short to ground, or too much current draw in that circuit.Either a short to ground, or too much current draw in that circuit.
You exceed the power dissipation capability of the device and it burns up. Too much voltage across the terminals , too much current being passed through it, reverse voltage spikes can all cause the triac to "blow".
