Contrac RHDE500 and RHDE800 Electrical Rotary Actuator Data Sheet

This data sheet describes the ABB Contrac RHDE500 and RHDE800 electrical rotary actuators, which are designed for continuous control, three-point position control, or bus control in explosion-proof applications. It details their operating principles, including stall-proof three-phase asynchronous motor operation, torque transfer via lever or direct coupling, and high-precision positioning for valve flaps and ball valves.
