DESCRIBE

The ABB 1SDA066149R1 (AUX‑C 1Q+1SY) is an auxiliary contact / trip‑status contact module designed to attach to circuit breakers from the ABB “FORMULA / SACE FORMULA / DSA” series. It adds two change‑over (CO / SPDT) auxiliary contacts: one for signalling breaker ON/OFF status (open/closed), and another for signalling “tripped” (breaker open due to fault) status. The module supports 3‑pole and 4‑pole breakers and can operate with control voltage up to 250 V (AC or DC). It’s used to provide remote indication or control logic (e.g. panel lamps, supervisory circuits, interlocks) based on breaker status. The module mounts alongside the breaker and integrates mechanically and electrically with the FORMULA‑series MCCB/MCCBs.
