Details

Three phase Autotransformer RC30H2-F has common primary-secondary windings which are not insulated from each other, offers no interference or disturbance isolation between primary and secondary circuits. It is an economical solution but is not suitable for sensitive equipment with electronic and servo components but perfectly suitable for simple motor/heater single or balanced applications. NOTE: standard 3 phase autotransformer comes without neutral lead, but if you need, please request the neutral lead from "Optional Features" tab.
