What differance between Circuit brekar and Isolater?

Answer Posted / shyamalmandirwala

Circuit Breaker is operated ON-LOAD whereas ISOLATOR can
not be operated ON LOAD as it does not have the arc
quenching medium as in the CIRCUIT BREAKER.
ISOLATOR is basically used for disconnecting a portion of
the power system for maintenance work to ensure safety of
persons doing maintenance work.

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
