9998 SL4 - Square D Contact Kit

9998 SL4 - Square D Contact Kit

The 9998 SL4 replacement contact kit is made for maintaining compatible NEMA Size 2 contactors and starters used in industrial and commercial electrical equipment. It fits Class 8502SD contactors, 8536SD Type S starters, and 8903SP lighting contactors, making it a useful replacement part for many existing motor control and lighting control systems still in operation today.

This 3-pole contact kit includes movable and stationary contacts along with the hardware needed for installation. In many facilities, replacing worn contacts is part of normal maintenance, especially on equipment that cycles on and off throughout the day. Instead of replacing the full assembly, technicians often replace the contact kit to help keep the original equipment in service and reduce downtime during repairs.

The 9998 SL4 is a professionally manufactured aftermarket replacement contact kit made in the U.S.A. and designed as a form, fit, and functional replacement for the original OEM kit. Its compact design works well in existing control panels and starter enclosures where space can be limited. For maintenance departments, contractors, and service electricians working with older motor control equipment, this kit provides a straightforward replacement option built for compatibility with the original assembly.
