Yes, a breaker will trip if there is a short circuit occurring on the breaker's connected load. The breaker will also trip on an overload condition when the current rises above the breakers trip set point.

2. unbalancing load condition it will be triped.
3. due to surge load.

What is meant by mcb and dp?
MCB = Miniature Circuit Breaker DP = Double Pole
What is the surge current limit for a 40 A MCB?
A 40A MCB is a circuit breaker. The surge current limit is protected to 250A 8/s0uS. The limitation capability of a circuit breaker is that characteristic whereby a current less then the prospective fault current is allowed to flow under short circuit conditions.
Will a rcd detect live to neutral fault?
No. An RCD operates by detecting fault currents on the circuit protective conductors(earth). An MCB(mini trip) should operate with a live to neutral fault(over-heating the circuit).
When will a 32 amp mcb trip?
The circuit protected by a 32 amp circuit breaker will trip when the circuit loading reaches on or about 32 amps. Theoretically a 32 amp breaker will not trip until current exceeds 32 amps. But this is affected by actual conditions such as ambient temperature, the integrity of the termination, the temperature of the breakers immediately adjacent to it, etc. In the United States the NEC requires that you not knowing load a breaker to greater than 80% of its rating. This avoids what is called nuisance tripping. Most common MCBs have an inverse-time component. This means the higher the current the faster it will trip. A current of 100 amps caused by a short circuit will trip faster than 33 amps which would most likely be an overload condition. The difference may not be noticeable without testing equipment.
How do you fix an electrical dead short in a house?
To avoid any short circuit in a house we suppose to have electrical panel with proper size of circuit breakers. These breakers installed to feed a number of circuits in the house which is controlled by the Electrical Code. The breaker ampacity is depend on the load size (light circuits, outlets, microwave, dryer, furnace, cenral vacuum). The individual circuits are calculated depend on the size of the load (like motors, transformers sucking a lot more power, current when they start) and this will be the base to figure out the proper wire size for feeding the circuit. When a short circuit occurs at the farthers point from the breaker this overcurrent device suppose to open up the circuit to avoid overheating ang fire.
What meaning mcb?
MCB, Miniature Circuit Breaker is electric switch which is used to protect against short circuits
What is the full form of MCB?
The definition of MCB is a miniature circuit breaker, it trips if there is a line to natural fault. Ill add some extra information about the different types. RCD - residual current device = This is what you could separate you're circuits up with by inserting 1 of these in you're consumer unit (if you have lets say 10 circuits it goes like this... rcd-mcb-mcb-mcb-mcb-mcb-rcd-mcb-mcb-mcb-mcb-mcb-main switch. you see the rcd's control 5 circuits each, if 1 of these circuits had an earth fault on it, the rcd will trip and 5 of them circuits will go off, which means you have to keep tripping in you're rcd with an mcb 1 at a time to see which circuit the fault is on. RCBO - residual current breaker with overload protection- These can be installed in place of mcb's and rcd's, the rcbo is an mcb and rcd in 1 breaker. For example, i have installed a consumer unit full of these, in this case if a circuit forms a fault then its only that circuit that goes off. I hope this extra piece of information helps you along and best of luck. <<>> In electrical terminology MCB stands for Miniature Circuit Breaker.
What is a mcb and what is it used for?
mcb is master circuit breaker. it is used in the circuit for the protection of equipments from over voltage.
What is mcb and cb?
MCB = Miniature Circit Breaker CB = Circuit Breaker
What is the 'short circuit capacity' of a 32A 60898 MCB?
Depends on manufacturer..Normally the ratings are as follows 1. Service short circuit breaking capacity is 7.5 kA 2. Rated short circuit breaking capacity is 10 kA.

What is the difference between MCB and MCCB?
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. MCB (Miniature Circuit Breaker)-rated current not more than 100 A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation.

What is difference between spn and tpn mcb db?
TPN MCB means Triple pole Neutral Miniature Circuit Breaker where as SPN MCB means single phase Neutral MCB.
Will a rcd detect live to neutral fault?
No. An RCD operates by detecting fault currents on the circuit protective conductors(earth). An MCB(mini trip) should operate with a live to neutral fault(over-heating the circuit).
What is the full form of MCB's in Physics?
It is miniature circuit breaker
What are the difference MCB and CB?
The main difference between MCB, RCCB, and Isolators Isolators are generally used in power system while on the other hand, MCB is the circuit breaker. Isolators are manually-operated device, and on the contrary, the circuit breaker is the automatically-operated device.
