JSR1 Series

Send Message Request a Quote

The JSR1 soft starter control panel determines how the AC motor works through the variable thyristor rectifier circuit by allowing the motor to start under lower voltages and run with less energy consumption. It features a small starting current, no contacts, no spark, and reliable protection for overload, open phase, and short circuit. When the electric control box is used in water pump motor, protection approaches are required against leakage, stator overheat, and high temperature bearings.
