Square D MA11286 Auxiliary Switch 10A 240V 1 3HP 50 60Hz 2A 2B Configuration

Square D MA11286 Auxiliary Switch delivers four contacts in a 2A/2B configuration, rated 10 A at 240 V and suitable for up to 1/3 HP loads at 50/60 Hz. This control accessory provides auxiliary signaling and feedback for Square D contactors and MCCBs in industrial panels, enabling remote monitoring or interlock-type logic without loading the main circuit. The device is designed to mount with compatible Square D frames; common applications include use with MA, MH, and MHL frame breakers, allowing auxiliary contact feedback to the control circuit. In documented configurations, the MA11286 is used as the auxiliary switch option with MHL-series 500 A MCCBs (where a MA11286-1A/1B pair is included), illustrating its role as a factory-installable option for enhanced control and protection schemes.
