Square D By Schneider Electric MA11284 Auxiliary Switch

MA11284 is a Square D by Schneider Electric auxiliary switch designed for use with Square D M‑Frame molded‑case circuit breakers (MA, MAL, MAP, MH, MHL, MHP). It provides one auxiliary contact pair rated for 125/250 V and a current capacity of 10 A at 120/240 V AC, configured in a 2A/2B arrangement to support dual signaling paths. This accessory matches the MA‑series mounting and electrical interfaces, enabling a secondary signaling contact for control circuits, remote monitoring, or interlocking functions without altering the main breaker’s form factor. When installed inside a breaker, the part number suffix is -1286, identifying this configured auxiliary switch arrangement for the MA/MAL/MAP/MH/MHL/MHP frames.
