DRA3P Series is a family of DIN Rail mount 3-phase Solid State Contactors with resistive ratings of 2.4 and 4.2 Amps per channel at 48-510 VAC, and motor ratings of 1 and 2 HP at 480 VAC. All the DRA3P series models are C-UL-US recognized. The DRA3P three phase solid state contactor is available in 2 configurations, with 2 or 3 controlled legs for added flexibility. In the case of the version with 2 controlled legs, the third leg is linked internally.
