The 275A16 is a brass jumper connector designed to connect two adjacent terminals in Curtis Series W and DW terminal block assemblies with 7/16" (11.11 mm) center-to-center spacing. This accessory component is constructed from plated brass and provides a simple, reliable method for bridging consecutive terminals without requiring additional wiring or lugs. The jumper is compatible with WT, DWT, WTC, and DWTC terminal block modules and integrates seamlessly with the snap-in track-type assembly concept. It is commonly used in electrical control panels, instrumentation systems, and industrial applications where compact terminal interconnection is required, offering reduced assembly time and improved circuit density.
