Furnas Electric Company R327AR Drum Controller

Description:

The Furnas R327AR Drum Controller is used in industrial motor control systems to provide forward, reverse, and stopping control of electric motors through a manually operated rotary drum switching mechanism. Commonly installed in legacy motor control panels, reversing starter circuits, hoists, conveyors, and industrial machinery where direct mechanical switching of motor direction is required. Maintenance teams, OEM rebuilders, and system integrators use this controller for equipment repair, replacement of worn drum switches, retrofit of legacy control systems, and restoration of industrial motor control functionality.

Applications:

The Furnas R327AR drum controller is commonly used in industrial environments including conveyor systems, machine tools, hoists, pumps, and material handling equipment where manual motor direction control and on/off switching are required for 1-phase and 3-phase motors in industrial control applications.
