The Sensata | Crydom DRMS Series Hybrid Motor Starters are an excellent solution for controlling small and medium 3-phase asynchronous motors. The DRMS48D93 Motor Starter comes with 6 integrated functions in the same device: Forward/Reverse, Soft Start/Soft Stop, Motor Overload Protection and Mains Isolating relay. The DRMS Series are compact DIN Rail mountable devices (only 22.5mm wide) which use hybrid relay technology, combining benefits of EMR switching with non-wearing solid state switching technology.
