Square D MA11284 Auxiliary Switch

Square D MA11284 Auxiliary Switch is a single auxiliary contact accessory designed for inclusion with Square D MA-series molded‑case circuit breakers. It provides one auxiliary switch and is compatible with MA, MAF, MAL, MAP, MH, MHF, MHL, and MHP frame breakers, expanding the control or signaling options available to the breaker assembly. The device is rated for 125/250 VAC, enabling it to operate with common control circuits without imposing on the main breaker contacts. When installed in a breaker, the accessory is identified by the suffix -1286, helping distinguish it from other MA accessories. Catalog listings for the MA11284 typically specify a 10 A load rating at 120/240 VAC for the auxiliary contact, underscoring its role as a signaling or interlock accessory rather than a primary switching element.
