RCCB means residual current circuit breaker. This is used
to trip the circuit in case of earth faults to prevent
electrical shocks.Different sensitivity ratings are
30ma,100 ma, 300 ma.These are used for Domestic, commercial
and Industrial electric loads respectively.

Answer / ravi

RCCB-Residual current circuit breaker.This is used in
Industrial safety purpose i.e. is to isolate the healthy
circuit whenever earth fault & overload current occurs.we
have in market at different type of ratings 30ma,100ma.as
per requirement will use above ratings.for example human
body having current flowing capacity of 30ma.so in
industrial as per safety constraint they will prefer 30ma
RCCB/ELCB.

Answer / sumit

residual current circuit breakern it works on a magnetic
current of circuit when circuit in healthy condition RCCB
works normaly but in any phase current going unbalance that
time RCCB will trip.because RCCB works on residual magnetic
current so unbalance current flows in relay & RCCB will
trip.

Answer / vikash kr jha

A residual current device (RCD), or residual current
circuit breaker (RCCB), is an electrical wiring device that
disconnects a circuit whenever it detects that the electric
current is not balanced between the phase ("hot") conductor
and the neutral conductor. Such an imbalance is sometimes
caused by current leakage through the body of a person who
is grounded and accidentally touching the energized part of
the circuit. A lethal shock can result from these
conditions; RCDs are designed to disconnect quickly enough
to mitigate the harm caused by such shocks.

Answer / rishabh singh

RCCB is a electrical device which is called residual current circuit breaker. It prevent the human body from electrical shocks.whenever current is flowing through earth(E) & Neutral that time RCCB prevent human body.

If breaker is undefined position, first step to do.
