Schneider Electric 9998-HC-1 Contact Kit

Schneider Electric’s Square D 9998-HC-1 Contact Kit is a Class 9998 replacement parts kit intended to service Square D relays, contactors, and starters, with compatibility tied to the HC10.170 assembly. This item is listed as a 9998-series contact kit and is noted by the manufacturer as discontinued. Weighing 0.17 lb, the kit is designed for field refurbishment of HC-series devices in legacy control panels, providing the essential contacts needed to restore proper operation without replacing the entire unit. While marketed as a genuine replacement kit, it aligns with Schneider Electric’s guidance that Class 9998 kits cover servicing Square D equipment, making it a targeted option for maintaining older installations that use HC10.170 components. When selecting this kit, confirm that HC10.170 is the correct mating assembly for your device to ensure proper fit and function.
