Square D MA11286 U Industrial Circuit Breaker

Square D MA11286 U is an auxiliary switch accessory designed for use with Square D MA-series molded-case circuit breakers, adding a second set of contacts for signaling or interlock control in industrial panels. It features a 2A/2B contact configuration and a rating of 10 A at 240 V AC, with an additional 1/3 HP rating at 50/60 Hz, enabling robust signaling in demanding environments. The device is intended to be mounted alongside the MA breaker in enclosures, allowing remote status indication or control signaling without imposing load on the main power path. This accessory complements the MA series by providing dedicated auxiliary contacts for automation and control circuits, helping integrate the breaker into larger control schemes.
