Circuit breakers do not have circuit diagrams. The breakers have an input where the distribution voltage is applied and an output where the load is applied. If you want to know what is inside a breaker, the electrical terminology to use is "shop drawings" of the specific breaker that you need information on.

Can you use molded breakers instead shunt trip breakers for an Ansul fire suppression system?
Moulded breakers or shunt trip breakers - selection is defined by the current rating requirement.
What is a circuit breaker?
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.Types:MCB (Miniature Circuit Breaker)-rated current not more than 100 A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation. Breakers illustrated above are in this category.MCCB (Molded Case Circuit Breaker)-rated current up to 2500 A. Thermal or thermal-magnetic operation. Trip current may be adjustable in larger ratings.Fuses - These come in various sizes and make ups. The downside is most fuses need replacing after tripping.
What is the purpose of current relay?
Electrical protection refers to the sense and command protective relay features provided to control the interruption of electrical service resulting from mechanical or electrical failures or other unacceptable conditions. Electrical Protection includes short circuit and overload protection provided by molded case circuit breakers and fuses, as well as relays. Relay protection is a collection of protective relay devices and systems which monitor the electrical characteristics of equipment and/or power distribution systems to assure power systems and equipment operation remain within predetermined limits. The protective devices initiate the removal from service of any piece of equipment and/or power system which is subjected to an abnormal operating condition exceeding preset limits.
What is SPN MCCB?
An SPN MCCB is a Solid Pole Neutral Molded Case Circuit Breaker.
What are the materials used to make an Xbox One controller?
Mostly molded plastics then printed circuit boards (plastic composites, copper traces, solder) then ICs (plastic, metal alloy leads, silicon chips, aluminum or gold bond wires) then minor miscellaneous materials.

Moulded breakers or shunt trip breakers - selection is defined by the current rating requirement.
For circuit breaker what does it mean by AF AT?
AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
What meaning of 63at-125af in electrical parameters?
AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size
What is the meaning of 200AT-250AF in circuit breaker?
250AF refers to the ampere rating of the breaker frame and 200AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
What is the meaning of 200AT 250AF in circuit breaker?
250AF refers to the ampere rating of the breaker frame and 200AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.

What type of molded case circuit breaker would you refer to a customer if they need a breaker that has UL and IEC certifications?
If you look closely at the label on all circuit breakers you should find the certifications. If it is not on there you should not be selling it. There is a lot of off shore counterfeit electrical equipment reaching the market place these days. Don't sell it and don't buy it. If you use these types of non certified equipment and it causes a fault and you try and claim it on an insurance claim, your claim might be turned down. Buyer be aware.
Where can you find a 2002 Toyota Highlander fuse box diagram?
If you no longer have the owner's manual - there is a diagram molded into the inside of the fuse box cover.
Function of molded case circuit breaker?
== == == == == == To open a circuit during an overcurrent event, thus protecting the cabling and devices connected to it.
