Siemens-Allis XL-3CC0 Three-Phase Motor Starter

Siemens-Allis XL-3CC0 is a size-3, three-phase motor starter rated for up to 600 VAC line voltage and designed to drive motors up to 50 HP, with a 115 V control coil. This compact, three-pole starter combines power switching for the main circuit with a 115 VAC control circuit, making it suitable for mid-range industrial applications where reliable starting of a 3-phase motor is required. Ideal for equipment such as pumps, fans, and conveyors in manufacturing and processing environments that use Siemens-Allis legacy components, the XL-3CC0 supports standard control-panel configurations with a robust frame that fits typical NEMA sizing. In operation, energizing the 115 V coil closes the three main contacts to allow current flow to the motor on up to 600 VAC lines, while the 50 HP maximum rating defines the upper bound of motor size for this starter. The XL-3CC0 is a hallmark of the Siemens-Allis era, offering a proven solution for controlling moderate-load motors in older installations or retrofits where compatible XL-series gear is present.
