Nietz - Model EDR Series -Low Voltage Soft Starter
EDR is a cost-effective soft starter that integrates intelligent control, industrial aesthetics, and safe output, specifically designed for 0.75-11kW asynchronous squirrel-cage motors. It serves as an excellent replacement for traditional contactors and star-delta starters. While ensuring sufficient current capacity, the product adopts an book-style design with a thickness of only 48mm, allowing for quick installation on standard DIN rails.
