Square D 9998SL-4N Limit Switch, 4 No Contacts

Square D by Schneider Electric 9998SL4 is a three-pole, size-2 contact kit designed to replace worn or damaged contacts in select Square D magnetic contactors and motor starters (Class 8502SD, 8536SD, 8538SD, and 8539SD). The kit provides four contacts to restore switching performance in 60 A, 600 VAC systems, compatible with 3-pole, NEMA size-2 devices. It includes movable and stationary contacts along with mounting hardware to facilitate replacement; contact springs are included only when required, with larger configurations (NEMA Size 3 and above) typically not including springs, and springs not available separately. This replacement kit is part of Schneider Electric's Class 9998 family, offering a direct substitute for worn-out OEM components in legacy Square D starters and contactors, helping extend the life of equipment without replacing the entire device. Typical applications include industrial motor control circuits where compact, robust contact replacement is needed for Size 2 contactors up to 60 A at up to 600 VAC, ensuring reliable make/break operations in control panels and motor control circuits.
