Square D 9998SL Series NEMA Contactor Replacement Contact Kit, 3 Pole

The Square D 9998SL Series replacement contact kit is engineered for Type S NEMA contactors and motor starters, including the 8502SD, 8536SD, and 8903SP families. This 3 pole kit line is available across NEMA Size 0 through NEMA Size 4 configurations, with amperage ratings spanning from lighter-duty sizes up to NEMA Size 4 at 200A, so maintenance teams can match the correct kit to the contactor or starter in service. Rather than replacing an entire contactor or starter assembly, technicians can swap worn Type S contacts in the field, restoring electrical performance and extending equipment life at a fraction of the cost of a full unit replacement. Each kit is halogen-free, mercury-free, and built without added toxic heavy metals, supporting cleaner maintenance practices in industrial and commercial facilities.

Square D 9998SL2 – Frequently Asked Questions

1) Which Square D contactors and starters does the 9998SL contact kit fit?
The 9998SL Series kits are for Type S NEMA contactors and motor starters, specifically the Class 8903 contactors and Class 8536 Type S starters, covering the 8502SD, 8536SD and 8903SP families. The 8502SD/8536SD side is motor control; 8903SP is lighting control. Match the kit to the NEMA size of the unit in service, not just the family name.
2) Which 9998SL part number do I order for a NEMA Size 2 starter?
Order by the NEMA size of the contactor: 9998SL2 for NEMA Size 0, 9998SL4 for NEMA Size 2 (60A), and 9998SL9 for NEMA Size 4 (200A). All three are 3 pole kits. The size stamped on the contactor nameplate is what decides it, so pull the cover and read it before ordering.
3) What are my options if my contactor is a Size 1, 6 or 7 rather than a Size 0, 2 or 4?
The Square D 9998SL kits offered cover NEMA Size 0, Size 2 (60A) and Size 4 (200A), so a Size 1 or a Size 6/7 frame needs something else. For Size 1, the Eaton A201 Model J contact kit covers three or four pole Size 1. For the large frames, the Eaton Citation Series C1 contact kit is a 3-pole kit for Size 6-7. Contact kits are frame-specific, so the brand and size have to match the contactor in the panel.
4) Will an Eaton A201 contact kit work in a Square D Type S NEMA contactor?
No. The Square D 9998SL contact kit is built specifically for Type S NEMA contactors and starters in the 8502SD, 8536SD, and 8903SP families. The Eaton 373B331G09 kit is an A201 Model J kit for three or four pole, Size 1 Eaton equipment, so it is a parallel part for a different manufacturer's contactor line rather than a drop-in for a Type S unit. Match the kit to the brand and series stamped on the contactor you are servicing.
5) What amperage range do the Square D 9998SL contact kits cover?
The 9998SL line spans 60A to 200A across the sizes offered, topping out at NEMA Size 4 rated 200A. The Size 0 kit covers the lighter-duty end. You are not selecting on amps directly, though: pick the kit that matches the contactor's NEMA size and the amp rating follows.
6) Is it worth replacing the contacts instead of swapping the whole contactor?
That is exactly what this kit is for. Worn Type S contacts can be changed in the field to restore electrical performance, so a panel with a pitted or welded contact set does not need a full contactor or starter assembly replaced. For a maintenance crew servicing several identical Type S starters, stocking the matching 9998SL kit per NEMA size keeps units in service.
7) Do Square D 9998SL contact kits meet RoHS and mercury-free requirements for our facility?
Yes. The 9998SL kits are RoHS compliant in EU scope, halogen free, mercury free, and built without added toxic heavy metals. That matters for institutional and government spec sheets that screen hazardous substances on MRO purchases. Country of origin is Mexico.
8) Can I use a 9998SL kit on a lighting contactor, or is it motor-control only?
Both. The 9998SL kits serve motor control units in the 8502SD and 8536SD families as well as lighting control contactors in the 8903SP family. Lighting contactor servicing and motor control panel maintenance are both listed applications, so a facility running both can standardize on the same kit series.
9) What is the difference between the Square D 9998SL and the Eaton 6601 contact kit?
Both are 3-pole replacement contact kits for NEMA contactors. The Square D 9998SL serves Type S contactors and starters in NEMA Size 0, Size 2 (60A), and Size 4 (200A), and is halogen-free, mercury-free, and RoHS compliant. The Eaton 6601 is a Series C1 Citation kit sized for Size 6-7 equipment. They cover different manufacturers' contactor lines and different size bands.
10) Is there a 4-pole alternative to the Square D 9998SL contact kit?
The Square D 9998SL kits are three-pole only. If the contactor in service needs four poles, the Eaton 373B331G09 A201 Model J kit is offered for three or four pole Size 1 contactors - though it applies to Eaton A201 equipment, so confirm the contactor nameplate before ordering.
