Schneider Electric MA11286 Auxiliary Switch 240V

Schneider Electric MA11286 Auxiliary Switch is a 240V AC signaling accessory designed for Square D MA, MH, MHL, and MAL frame circuit breakers. This two-contact (2A/2B) auxiliary switch provides signaling that changes state in step with the main breaker, enabling remote indication or control circuits without carrying main load. Rated for 10A and 1/3 horsepower, it operates at 50/60 Hz and mounts inside the breaker frame (internal/panel mount) for a compact, integrated signaling solution. Typical applications include status indication in control panels, remote alarm signaling, and signaling interlocks in industrial controls, where the auxiliary contacts are used to drive auxiliary circuits or feedback signals in process and machine controls. To ensure proper fit, verify compatibility with the exact MA/MH/MAL/MHL breaker model and consult the Schneider Electric documentation for wiring diagrams and terminal assignments. This accessory complements the MA family by providing reliable, mechanical signaling that reflects the breaker’s on/off state, helping operators monitor and integrate circuit protection within broader control schemes.
