The ABB AUX‑C 1Q1SY 250 V (T1‑T3) is a cabled auxiliary contact accessory designed to provide status signaling and trip indication when fitted to ABB molded case circuit breakers such as the Tmax XT1, XT2, and XT3 series. This module features two changeover (SPDT) contacts: one contact signals the open/closed position of the breaker’s main contacts, and the other signals a trip event (such as overload or fault) when the breaker opens. The pre‑wired design with a cable allows easy integration into control, monitoring, or automation circuits for real‑time feedback of breaker status. The unit is suitable for both AC and DC control voltages up to 250 V, and installs directly into dedicated accessory slots on compatible breakers.
