In the US a miniature circuit breaker, sold in a single unit, is about 15$, about the same as a regular breaker. If sold as a double unit, meaning two mini breakers installed into one housing, then it is about 25$.

What are the differences between a Miniature Circuit Breaker and normal Circuit Breaker?
An air circuit breaker, or air-blast circuit breaker, is a type of circuit breaker used in high-voltage transmission/distribution systems. It uses compressed air to (a) operate its tripping mechanism, and (b) to extinguish the arc created by a fault current. A miniature circuit breaker is a type of circuit breaker used in low-voltage applications, such as the protection of lighting and power circuits in a domestic residence. It uses a spring to operate its tripping mechanism, and relies on the speed of operation to extinguish the arc created by a fault current. Apart from the fact they are both designed to interrupt a fault current, there is really no other similarity.
What is a Circuit breaker and explain type circuit breakers?
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.
What is a switch that opens a cuircut when too much current is flowing?
Where I'm from, it's called a "circuit breaker".A circuit breaker.
What is miniature CB?
circuit breaker
What is mcb and cb?
MCB = Miniature Circit Breaker CB = Circuit Breaker
What is miniature circuit breakers?
miniature circuit breaker or MCB in low voltage electrical network instead of fuse.
What is the full form of MCB's in Physics?
It is miniature circuit breaker
What is the advantage of Miniature Circuit Breaker?
Miniature circuit breakers are smaller & easier to instal. It occupy less space & are more efficient
What is meant by mcb and dp?
MCB = Miniature Circuit Breaker DP = Double Pole
What is the difference between fuse and MCB?
what is the difference between miniature circuit breaker and fuse
What meaning mcb?
MCB, Miniature Circuit Breaker is electric switch which is used to protect against short circuits
What is the rated short circuit capacity of the miniature circuit breaker used?
Breaking Current: The r.m.s value of short circuit current at the instant of contact separation.
What type of circuit breaker is required for a 240 v branch circuit?
the circuit breaker used will be miniature circuit breaker(MCB) maily used in homes.Answer for USA, Canada and countries running a 60 Hertz supply service.A two pole circuit breaker is used for a load of 240 volts. It is sized, according to the load amps of the device, to protect the wires that supply the load current.
How does a circuit breaker know that the voltage is high or low and trip off?
A circuit breaker doesn't respond to excessive voltages, but to excessive currents (overcurrents). A miniature circuit breaker, the type you have at home, has a bimetallic strip and a coil, either of which will initiate a trip in response to excessive temperature (overload currents) or excessive magnetic flux density (short-circuit currents).
What is mean by 4 pole ELMCB?
Earth leakage miniature circuit breaker (mcb+ecb=rcbo) rcbo is called elcmb
