DRA Series Solid State Contactors offer the advantages of Crydom's proven state-of-the-art solid state AC

switching technology in a ready-to-use contactor which requires no additional heat sinking. DRA Series

Contactors include a protective Forward/Reverse interlock for motor reversing and are ideal for applications

up to 2 Horse Power. For complete specifications, see DRA Series AC 3 Phase Contactors & DRA AC Motor

Reversing Contactors datasheets at www.crydom.com.

Install the contactor on the DIN rail as shown in fig. 1. Vertical

mounting operation is recommended.

If multiple units are installed be sure to follow derating curve (fig. 2).
