Allis-Chalmers D71221-1 Motor Control Coil 110-208-220V 60-50CY

Allis-Chalmers D71221-1 Motor Control Coil is a 110/208/220 VAC coil designed to energize control circuits in Allis-Chalmers equipment, serving as the energizing element for compatible motor starters and contactors used in industrial wiring and automation setups. The 60-50CY designation indicates dual frequency compatibility, meaning the coil can operate within power systems that run at either 60 Hz or 50 Hz, a common configuration in North American and international facilities. The D71221-1 model code helps technicians identify the coil's exact electrical characteristics and physical form factor, ensuring correct replacement or refurbishment within an integrated Allis-Chalmers motor control assembly. Because it is a dedicated motor control coil, it is intended to energize the coil winding that actuates contact closures in the associated control hardware, enabling reliable motor start/stop sequences in industrial machinery.
