A circuit breaker works by tripping a switch when too much current passes through it. As you may know, the higher the flow of energy, given a fixed resistance, the more heat will be generated. Because of this property, the heating of a metal strip (usually made from 2 different types of metals, so that it bends) is the mechanism for circuit discontinuation in a circuit breaker.
Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.

Short circuit fault.
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.
Square D circuit breakers can be purchased from various homeware and DIY stores such as Home Depot or Lowes. Websites that specialise in circuit breakers such as Circuit Breaker Service or All Breakers do sell them as well.
most circuit breakers are under the hood near the battery. major breakers. you have to unscrew cover.
GE circuit breakers with catalog numbers ranging from THQL1115 through to THQL1150 can be substituted like for like with Cutler-Hammer circuit breakers coded CL115 through to CL150, ITE Siemens circuit breakers coded Q115 through to Q150 and Square D circuit breakers coded HOM115 through to HOM150. These are single pole breakers. GE circuit breakers with catalog codes from THQL2115 through to THQL2150 can be substituted with Cutler-Hammer circuit breakers CL215 through to CL250, Square D circuit breakers HOM215 through to HOM250 and ITE Siemens circuit breakers Q215 through to Q250 of the same amperage and voltage. These are double pole breakers.
Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.
3 pole circuit breakers are used for 3 phase lines
Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
Lowes and Home Depot carry circuit breakers as well as the wiring and box. Circuit Breakers come in several watts, so be sure you get what is appropriate for your living space.
Circuit breakers operate. is the operetion of the break of the circuit. FORMULA : f(x) = m x+b
Circuit protectors are fuses and circuit breakers.
No, not all circuit breakers are automatically reset. Some circuit breakers need to be manually reset by flipping the switch back to the "on" position after they have tripped. Automatic reset circuit breakers are typically used in specific applications where it is important for the circuit to be quickly restored without human intervention.
The different types of Square D breakers available for residential electrical panels include standard circuit breakers, tandem circuit breakers, and arc fault circuit interrupters (AFCIs).
