circuit breakers provide two basic forms of protection: overcurrent and short circuit The mechanism used on most simple breakers for overcurrent is a calibrated bimetalic strip > when it draws two much current it gets hot and bends the strip to trip a mechanical arm The mechanism used for short circuit is a electro-magnetic coil > when a fault current goes through the coil, it magnetically attracts a ferrous lever that trips a mechanical release Many larger breakers have electronic trips which monitor the above two functions plus others functions electronically, and a microprocessor then desides to trip the mechanical release

A Murray or similar breaker would work but most inspectors want the brand breaker to match the brand panel.
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
Before anyone is allowed to work on a high-voltage circuit breaker, it must be tripped, electrically isolated, earthed (grounded), barriers/warning notices put in place, and a permit to work document issued by an engineer to the senior member of the maintenance crew. 'Isolation' means a physical (and visible) break in the conductors between the circuit breaker and any potential source of supply -and this is provided by placing isolator switches on each side of the circuit breaker. Without these isolators, the circuit breaker would remain energized, even though the circuit has been broken by the circuit breaker.
Where I'm from, it's called a "circuit breaker".A circuit breaker.

A manual circuit breaker must be reset by hand, as opposed to an automatic circuit breaker, that may be able to reset itself once it cools down.

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.

An open circuit does not work. You need to have a complete circuit for the electrical current to flow back to its source. For example: An open circuit occurs when a series fuse blows or a connector is unplugged.
Power windows are protected by an automatic resetting circuit breaker.
bulb burned out; fuse/circuit breaker open
