A circuit breaker was examined to determine how it worksBasically it is designed to disconnect the current if the current passingthrough the breaker is higher than the allowable current Its main partsconsist of a switch connecting pads and the disconnect device Sincethe breaker consists of many individual parts the only improvement foundwas to combine some of the parts into a single partOur group dissected a thirty-amp household Circuit-breaker Its purpose isto protect electrical appliances from being damaged though excessivecurrents A circuit breaker limits the amount of current that may safelyenter a household electrical system via a predetermined amperage ratingIt is placed in series between your house and the provided electricityAny current in excess of the rated current amount will trip the circuitbreaker in to a non-conducting or open path condition The closed path ismaintained until either magnetism or thermal expansion causes the circuitThe circuit breaker has several features that are worth noting in thedesign discussion First is its ability to detect various types of loadingsituations The breaker can not only open a circuit in response to acurrent spike but can also react to a sustained moderate current drawjust above its rated current The circuit breaker also has an easilyresetable 3-position switch and various internal safety features such as Operation of the circuit breaker is simple but utilizes complexmechanisms Essentially there are to main internal mechanisms the triggerand the switch The trigger is the device that senses the abnormal currentload A sharp spike in current will cause a magnetic field to form in thetrigger releasing the switch A slightly elevated but more constantcurrent draw through the breaker will cause the bi-metal composition ofthe trigger mechanism to deflect in an arc like manner which is alsocapable of releasing the switch This reaction may take a longer amount oftime to open the circuit but is designed to provide the user with a shorttime of extended current draw through the circuit before the breaker The switch which
