Schneider Electric PA11212 Auxiliary Contact Switch

Schneider Electric PA11212 is an auxiliary contact switch designed for the PA/PH/PC/PE/PX family of molded‑case circuit breakers. It provides a pair of auxiliary contacts designated 1A/1B that interface with 125–250 VAC control circuits, enabling status signaling or interlock logic without changing the breaker’s main switching function. This accessory expands a panel’s monitoring and automation capabilities by delivering independent contact outputs that can feed PLCs, relays, or indicator circuits. The PA11212 is intended for use with Schneider Electric’s PA, PH, PC, PE, and PX breakers, ensuring electrical compatibility and a compact form factor that fits within standard control panel layouts. Typical applications include signaling the breaker position to automation systems, driving indicator lamps, or feeding control logic in motor control centers and industrial panels, all while preserving the integrity of the primary power path. This part is a factory-compatible accessory within Schneider Electric’s line of PA/PH/PC/PE/PX breakers, designed to be installed alongside the corresponding breaker to provide reliable auxiliary feedback in demanding environments.
