Motor starting reactors are used to reduce voltage during starting of large 3 phase motors while limiting inrush currents.
Large motors generally draw 6-8 times more current than their nominal current. Typically, they are started with 70% voltage while the remaining 30% is dispersed via the motor starting reactor. After 15 – 20 seconds, the reactor is switched off by contactors in the system.
Advantages
l Perfect mechanical strength to withstand high short-circuit forces
l Limited temperature rise enables longer lifetime
l Special surface protection against UV and pollution Class IV areas
l Maintenance-free design
