Square D 8536 Contact Kits

Square D 8536 contact kits are replacement contact kits used to service compatible Class 8536 Type S NEMA motor starters. The Class 9998 replacement kit series covers different 8536 starter sizes, with the correct kit number depending on the starter type and NEMA size.

These kits are intended for maintenance and contact replacement rather than complete starter replacement. Depending on the equipment configuration, a kit can include movable and stationary contacts, contact springs where applicable, and other required hardware.

Applications

Square D 8536 contact kits are used for maintenance of Type S full-voltage NEMA motor starters in industrial motor-control applications. They are suitable when the contact components require replacement but the existing starter remains otherwise serviceable. Certain Class 9998 kits may also apply to related Square D contactors and lighting contactors depending on the specific Type and Size.

Why Replace the Contact Kit?

Contact surfaces experience electrical and mechanical wear during repeated switching. A replacement kit can renew these components without replacing the entire starter, helping maintenance teams extend the service life of compatible equipment.
