3-Phase Isolator: Key Uses & Benefits in Electrical Systems
                     What Is a 3-Phase Isolator?
A guide to 3-phase isolators: working principles, benefits, and key 
considerations.
How 3-Phase Isolators Work
A 3-phase isolator is a manually operated mechanical switch designed to completely disconnect a 
three-phase electrical circuit from its power supply.
