Schneider Electric 9998SJ1 Contact Kit 3Pole Assembly

9998SJ1 is a direct-mount replacement contact kit for Schneider Electric Square D Type S NEMA Size 00 three-pole contactors and motor starters. Specifically designed for use with 8502SA contactors and 8536SA starters (Series B devices), this kit provides the movable and stationary contacts plus the mounting hardware needed to restore all three poles. It uses screw-clamp (TC) connections for secure wiring and is rated for up to 600 V AC with a 9 A contact rating, aligning with typical Size 00 Type S applications. As a replacement part, it preserves the original equipment’s electrical characteristics while extending service life by renewing worn contacts without replacing the entire assembly. The 9998SJ1 designation identifies it as a Class 9998 SJ1 replacement kit for 3-pole, Size 00 configurations compatible with NEMA motor control gear, making it suitable for light- to medium-duty motor control tasks in systems that employ 8502SA/8536SA devices.
