There are several type of circuit breakers now a day we are using these are as follows:
1. M.C.B. (Miniature circuit Breaker)
Rating : 1, 2, 4, 6, 10, 16, 20, 25, 32, 63 Amperes
2. M.C.C.B. (Miniature current circuit Breaker)
Rating : 10, 16, 20, 25, 32, 63, 100, 200, 250, 400 Amperes.
3. A.C.B. (Air Circuit Breaker)
Rating : 400, 800, 1000, 1200, 1500, 1800, 2000 Amperes.
4. A. B. Switch (Air Breaker)
used in High tension line.
5. SF6 Breaker (Contact break in the Sf6 medium)
used in High tension line.

∙ 16y agoCircuit breakers, like fusible links (fuses), are rated according to the maximum amount of current (load) they can support before the circuit is interrupted. Many appliances have their own circuit breakers, typically rated at something less than 10 amps.
In general, breakers are designed to open (turn off the circuit) when the current has been slightly exceeded for more than a few seconds, or greatly exceeded for less than a second. If you're attached to the circuit, you'd be electrocuted before the breaker blew, but at least the house wouldn't burn down.
Home circuit breakers come in many sizes and configurations, ranging from 15 amps to 400 amps (for main disconnect), with intermediate sizes including 20, 30, 40, 50, 60, 70, 100, 150 and 200 amps, among others.
Breakers are also classed by how many poles they have, whether both poles open simultaneously, what additional safety features there are (GFCI, arc-fault), who makes them, and what model panelboard they are to be installed into.

An adjustable trip breaker can be set to trip at varying values of current or time or both.
An instantaneous trip breaker has no time delay before the tripping action.
In an inverse time breaker the delay to trip decreases as the current increases.
An arc-fault breaker is designed to recognize the characteristics unique to arcing and open the circuit.
A ground fault breaker is intended for the protection of personnel by recognizing current to ground leakage.

What is the ACB circuit breaker?
The letters ACB stand for Air Circuit Breaker. These types of circuit breakers are used for high voltage switching. The breakers are usually enclosed in steel switch gear enclosures that are situated in electrical service vaults.
Can different rating circuit breakers have the same short circuit characteristics?
Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
Will multiple tripping of a circuit breaker damage the circuit breaker?
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.
What fuses and circuit breakers provide protection in the event of?
Short circuit fault.
Which type of circuit breakers used in EHT applications?
SF6 circuit breaker
Are there different types of Circut breakers?
There are several different types of circuit breakers that can carry various electrical loads.
What circuit protector?
It is usually classed as a device that will open the circuit if the current in the circuit goes high. Two examples of these types of devices are fuses and circuit breakers.
What is vacuum interrupter?
Vacuum interrupters are special types of high-voltage circuit breakers.
When would you need to use westinghouse circuit breakers?
You need these types of circuit breakers when using 240 volt power rather than 120 volt. Large appliances such as a dryer require these larger circuit breakers. Other appliances such as stoves and some water heaters also require them.
What is the ACB circuit breaker?
The letters ACB stand for Air Circuit Breaker. These types of circuit breakers are used for high voltage switching. The breakers are usually enclosed in steel switch gear enclosures that are situated in electrical service vaults.

Where can Square D circuit breakers be purchased?
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.
Where are the circuit breakers on a 2000 chev Tahoe?
most circuit breakers are under the hood near the battery. major breakers. you have to unscrew cover.
What breakers are compatible with ge breaker boxes?
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.
Is gold used in circuit 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?
3 pole circuit breakers are used for 3 phase lines
