Industrial BBI 9998SL7 N NOT SD7LCS Limit Switch

9998SL7 N is a Square D three-pole replacement contact kit designed for NEMA size 3 motor starters. This aftermarket kit (NOT OEM SD7LCS) provides the trio of power contacts needed to restore switching performance when wear or arcing has degraded a starter’s original contacts. The assembly supports a 3P configuration and is rated for up to 90 amps and up to 600 V AC, making it suitable for common lighting and motor-load applications in industrial settings. Because it is listed as NOT OEM SD7LCS, it is marketed as a non‑OEM alternative rather than an original Square D SD7LCS part. Typical uses include repair or refurbishment of Square D motor-control gear in equipment such as conveyors, pumps, fans, and machine tools where a 3-pole, NEMA size 3 contact kit is appropriate. The 9998SL7 is a replacement component intended to drop into compatible Square D starters, helping to extend the life of the control circuit without replacing the entire starter. When selecting this kit, verify the pole count, voltage rating, and that your starter requires a 3-pole contact kit for Square D 3-pole motor-control assemblies.
