9999SM12 | Square D | Relays & Contactors

The 9999SM12 is a Schneider Electric Type S NEMA contactor (mechanical interlock kit, horizontal mounting, 2-5 pole, NEMA size 3-4).

Type S reversing magnetic contactors and starters are used for starting, stopping and reversing AC motors. Type S reversing contactors and starters are availble in NEMA Sizes 00 through 7. Type S contactors or starters can be mechanically interlocked so that only one device is energized at a time. The mechanical interlock is an interference (non-jamming) type, locking at the beginning of the stroke of any starter or contactor. The mechanical interlock is separate from the mounting pan on NEMA Sizes 3 and 4.
