• NJR5-ZX is high performance soft-starter, which is mainly used for soft starting and stopping of the motor. By reducing the starting voltage and current, the motor can start smoothly and reliably, to reduce the impact force on the equipment, reduce the damage to the equipment and prolong the service life. At the same time, the soft starter also has the basic protection function of the motor comprehensive protector. • Wide voltage: 220V ~690V
• 7 starting modes • Smooth jump-start
