Answer / anand yadav

The isolators are manually operated switches rated for different voltages and current and selected as per application. The isolators are of two types:
Off Load Isolator and On Load Isolators.
Off Load Isolators cannot be used to break the circuit on load, so it is provided with some mechanical or electrical interlock to avoid on load breaking, otherwise it may be dangerous for operator and the equipment.
On Load Isolator can be used to break the circuit on load but cannot substitute the Breaker.
The Breakers have remote operating features with many in built protections and so many add on protections with high breaking and making capacity.
Hence Isolator cannot be used as Breaker.
