Answer / reshi

Circuit Breaker is used to isolate the power supply to the
equipment and avoid any damaged to the equipment during
the short circuit or overload.
Circuit breaket are of two types magnetic trip &
adjustable trip type.In adjustable there is the option of
adjusting the breaker to trip intantaneously or taking
short time or taking long time on crossing the particular
values.There are many types of MV Circuit Breakers.
1.Air Circuit Breakers
2.Vaccum Circuit Breaker
3.Oil Circuit Breakers

and in LV :
1. MCCB moulded case circuit breaker
2. MCB miniature circuit breaker
3. ELCB earth leakage circuit breaker.

Answer / v.balakrishnan,shj

Circuit breaker is used to break the power supply from
loads like switch, but it also protects loads from over
current, short circuit and earth fault.
Types of Circuit breakers as follows:-
MV
1.Air Circuit Breaker (ACB)
2.Vaccum Circuit Breaker (VCB)
3.Oil Circuit Breaker
4.SF6 Circuit Breaker
LV
1.Air Circuit Breaker (ACB)
2.Moulded Case Circuit Breaker (MCCB)
3.Earth Leakage Circuit Breaker (ELCB)
4.Miniature Circuit Breaker (MCB)
5.Motor Protection Circuit Breaker (MPCB)

Answer / a.muthu kumar

Circuit breaker is used to protecting the circuit
from overload and short circuting.
There are so many types of circuit breakers are
available.
1)MCB-Mini Circuit Breaker,
2)MCCB-Module Cash Circuit Breaker,
3)ELCB-Earth Leakaging Circuit Breaker.

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.

my question is that....few days ago i had installed a three phase motor starter for an electric saw.the motor will run and make the hydraulic pressure which will be goes to pressure cylender by up and down lever.two number of limitswitches are also installed on cylinder for safety of motor.now when the arm of cylinder reaches to the upper or lower limit it will cut the motor's line.and motor will be stop.now wana know that what will i do that motor runs continue after the limitswitch cut it down but it shold not be made any pressure.pls answer me in brief.
