Why Choose the Lovato SDSI55415 Star Delta Starter?
The Lovato SDSI55415 is a robust star delta motor starter designed for reliable starting and control of three-phase industrial motors. As part of the Lovato SDSI Star Delta Starter series, it provides a complete motor starting solution with integrated switching components, overload protection and isolation for industrial automation and machinery applications.
This starter reduces the high inrush current associated with direct-on-line motor starting by initially connecting the motor in star configuration before switching to delta operation. The integrated enclosure, thermal overload relay and isolator provide a practical solution for protecting motors and simplifying installation in demanding industrial environments.
With a motor power rating of 55 kW, a 400 V AC three-phase supply and a maximum motor current rating of 105 A, the SDSI55415 is suitable for larger industrial motors used in pumps, fans, compressors, conveyors and production machinery.
