Westinghouse PBK-11 A200 Accessory Kit

The Westinghouse PBK-11 is an accessory kit specifically designed for the A200 series of motor starters and contactors, providing auxiliary contacts to expand control capabilities. This kit includes a side-mount auxiliary contact block with 1 normally open (NO) and 1 normally closed (NC) contact, pre-wired color-coded cables for quick connections, and a metal mounting bracket for secure installation. It is ideal for industrial applications requiring additional signaling, interlocking, or control functions, such as in motor-driven systems for conveyors, pumps, compressors, and fans in manufacturing, oil and gas, and utility sectors. Key features include robust construction for reliability in demanding environments, easy integration without tools, and compatibility with A200 series sizes 00 to 4. Benefits encompass enhanced system flexibility, improved safety through additional monitoring, and cost-effective upgrades for legacy equipment. Drawbacks may include limited availability due to the product's vintage status (Westinghouse now under Eaton) and potential incompatibility with modern digital controls without modifications. Compared to similar auxiliary kits from competitors like Siemens or Allen-Bradley, the PBK-11 offers superior durability for heavy-duty use at a lower cost for maintaining older installations, though it lacks advanced features like LED indicators found in newer models. Overall, it provides a reliable solution for extending the life and functionality of A200-based control systems.
