Solutions that Match Requirements
ISA HD - Medium Voltage SST
Reliable Medium-Voltage Motor Starting
The ISA HD is a heavy-duty medium-voltage soft starter for AC induction motors. It delivers smooth, controlled motor starting and stopping in demanding industrial applications. The advanced control technology reduces electrical and mechanical stress while improving system reliability.
Reduce Stress. Improve Performance.
The ISA HD limits inrush current, voltage dips, and torque shocks during startup. As a result, motors and driven equipment experience less wear. This helps extend equipment life and reduce maintenance costs.
Flexible control functions allow users to optimize performance for different applications. The ISA HD is ideal for pumps, fans, compressors, conveyors, crushers, and other critical motor-driven equipment. In addition, advanced monitoring and diagnostics provide clear visibility into motor and system performance.
Simplify Maintenance
The ISA HD features a withdrawable power module design. Maintenance teams can quickly access critical power components for inspection or service. This reduces maintenance time and lowers Mean Time To Repair (MTTR). As a result, downtime is minimized and equipment availability is increased.
With a proven track record in mining, water and wastewater, marine, power generation, and heavy industry, the ISA HD is a trusted solution for medium-voltage motor starting. It combines reliable motor control, comprehensive protection, and simplified maintenance in a single robust platform.
