Square D MA11286 Auxiliary Switch is a 120–240 VAC auxiliary contact accessory for Square D MA/MH/MAL/MHL frame circuit breakers that provides a second, independent 2A/2B contact pair for status signaling. Rated at 10 A at 240 VAC and supporting 1/3 HP at 50/60 Hz, it enables remote monitoring or interlock circuits without loading the main contacts. Install on compatible Square D breakers to gain feedback for control circuitry in 120/240 VAC systems.
