Answer Posted / rajesh ku sahu
Basic difference between circuit breaker and contractor is
That, A circuit breaker can make, break and carry current
in all conditions i.e normal, overload and short circuit.
It will protect the system from over load, Earth fault &
unbalance as well as it has different load & trip setting
and it don’t want any fuse back up. That was not inbuilt in
contactor. A contractor can make, break and carry only in
normal and overloaded condition not in short circuit
condition. Also, Contractor are always backup by HRC fuse
where as there is no need of any backup in circuit breaker.
For frequent operation, contractor is more efficient than
the Circuit breaker.
