Single-motor Soft Starter

NR1000 series 90kW~115kW high-power built-in bypass soft starter is specially developed for heavy-duty high-current 380V three-phase squirrel cage motors, adopting upgraded large-current thyristor module and enhanced heat dissipation air channel structure. This power segment upgrades to 3 independent programmable relay output channels, standard integrated 4-20mA analog monitoring terminal, and strengthens short-circuit breaking capacity for high-current industrial equipment. The built-in bypass contactor greatly reduces long-term thyristor heat generation, solving overheating failure risks of high-power soft starters under 24-hour continuous running, widely used in mining, water conservancy and heavy crushing industrial sites.
