product details

Hydroman^® WePanel™ HSD Star Delta Starters use contactors to reduce the voltage applied to each winding of 3 phase AC induction motors to about 58% of the line voltage. This reduces the starting torque and current for a variable amount of time (standard 1-30 seconds) and then switches over to Delta.
