Answer / kunal
An isolator can be operted only at no load condition,because
there is no arc-quenching medium in isolator,where as
breaker can be operated at both On-load condition & off-load
condition,since it has arc-quenching medium.

Answer / esam hamdy
An isolator is the gate of the voltage while a breaker is
the gate of the current in a bay. The isolator opens and
closes only on zero current while the breaker opens and
closes on zero current, full load current and short circuit
current so, the breaker has arc-quenching medium and the
isolator has not.
