The Sensata | Crydom DRH Series is a family of compact DIN Rail Mount, IEC standard based Solid State Contactors. The DRH3P60A18R in the DRH Series has a rating of 18 Amps per channel at 600 VAC with AC control and Instantaneous (inductive loads) turn-on output. The DRH Series is ideal for heating applications of 18A per phase and can also be used to control (start/stop) 3-phase motors of up to 5HP at 480 VAC. It is an effective solution for replacement of electromechanical contactors in commercial and industrial applications that require frequent switching.
