Starting with stator reactors is suitable for electric pumps with cage rotor motor in which the voltage drop is produced by reactors placed in series at the stator during the starting phase.
The starting current is limited to about half of what you would have with the start at full voltage. At the end of the acceleration phase, the reactors are excluded (controlled by a timer) and the motor returns to the full voltage parameters.
The entire REACTO serie is offered as standard with metal box IP55, are then available a whole series of accessories and optional including double door box and fiberglass casings.
