ABB PSR105-600-70 Softstarter (1SFA896115R7000)

The ABB PSR105-600-70 softstarter is a compact and efficient motor starting solution designed for industrial three-phase motors up to 105 A. With a voltage range of 208–600 V AC and rated control voltage of 100–240 V AC, it ensures smooth start and stop via two-phase voltage ramping. The integrated bypass contactor enhances installation ease and reduces heat dissipation.

Ideal for applications such as compressors, pumps, conveyors, and fans, the PSR105-600-70 provides high starting reliability in space-constrained panels.
