what is difference between switch and circuit breaker 


                                                       switch

~A switch is used to close a circuit with a low current flowing through it.

~ The switch is not used to break the current fault current i.e. is useful only in healthy simulations.  The operation of the switch is manual.

~ The voltage level is low.

~ The design is simple and straightforward.

~ Less maintenance required.

~ Occupies less space.  

~ There are usually indoor types.  

~ Is less expensive.


                                                    circuit breaker

~ In which a circuit breaker is used to break a circuit where the current value is much higher.

~ Useful for circuit breakers even when there is a fault in the circuit I.e. also useful in fault condition.  

~ The operation of circuit breaker is manual as well as automatic.

~ The trip coil is operated through the protection relay and turns the breaker off.

~ Made for high and extra high voltage rating from normal voltage level.

~ The design is confusing and made for extra high voltage rating.

~ Regular maintenance is required.  Occupies more space.

~ Depending on the rating and type, there are both outdoor and indoor types.  Incredibly expensive.
