Square D 9999SP2R N Industrial Relay Module Unit is a NEMA 1 pilot-light kit designed for 2- or 3-pole Square D 9999 contactors/starters in sizes 00–1. It adds dual incandescent pilot lights (red and green) to indicate coil status inside a NEMA 1 enclosure, making it ideal for 120 VAC control circuits up to 30 A. This field-installable module directly complements 9999-series contactors and starters, and includes red and green lens covers for clear visibility. The -N suffix denotes this specific variant of the pilot-light kit for use with these contactors in industrial control panels.
