RSGT Series Soft Starters for AC 3-Phase Induction Motors

The RSGT Series Soft Starters are an easy-to-use product range for AC 3-phase induction motors up to 75 hp (55kW). Only three settings are required (FLC, ramp-up, ramp-down). The self-learning algorithm adjusts the soft starter's parameters to work with different applications and varying load conditions.

The integration of a Class 10 electronic overload provides advanced motor protection and space savings in the electrical panel. Phase sequence protection, overload function, and dry run function can easily be enabled or disabled through the front-located test/reset push button.

Additionally, the series has a Modbus/RTU communication port with a 2-wire RS485 connection, allowing complete real-time monitoring of the product.

The RSGT Series Soft Starters are ideally designed for HVAC, conveyors, agriculture, smart building, and water/wastewater markets.
