Reliance Electric K-268 Contactor Assembly Kit

The Reliance Electric K-268 Contactor Assembly Kit is an auxiliary contact kit that adds four normally open contacts to a Reliance Electric contactor, expanding the control pathways available in legacy motor starters. It installs with simple snap-in action and requires no tools; you simply hold the contactor steady and press the kit into the proper position. When mounted on a single side, the kit increases the contactor width by about 0.5 inches; a side-mounting kit can add four more contacts per side for a total of eight auxiliary contacts. The K-268 is a discontinued Reliance Electric accessory, and contemporary listings describe it as surplus or reconditioned stock rather than a new item. It is typically used with older Reliance contactors and is referenced in retailer catalogs as compatible with models such as 78091-50R/51R. Because it’s discontinued, availability is limited to secondary-market suppliers, and installations should verify compatibility with the target contactor’s mounting dimensions and clearance.
