A higher voltage means that a higher current will flow in the same load. It is the current that causes the breaker to trip.
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.
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).
Generally circuit breaker is not designed to trip off in the event of lightning. The system has lightning arrestors which reroute the lightning effect to earth instantly. If there are no lightning arrestors then the equipment are likely to fail upon a lightning strike.
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
Yes, but you need a power source, for the shunt trip coil voltage, in the circuit.
A circuit breaker is designed so that it will trip when the electric current is too high. That is the purpose of a circuit breaker. If there is a metal piece on the circuit breaker that prevents it from tripping, it is useless. Perhaps someone has altered it.
No, it does not have voltage in trip position.
Yes this could be true. The breaker to the load will have tripped. The main breaker should still be allowing voltage to the distribution panel because it did not trip. If the main breaker tripped then the distribution panel must have been close to maximum amperage and the shorting of the branch circuit was enough to trip the mains.

ELCB means Earth Leakage Circuit Breaker -- it is used to trip the Circuit breaker if any leakage fault occured means
The ampere frame rating for a circuit breaker designates how the circuit breaker should be configured. It also states the trip unit of the amp.
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
