ABB CB1-611R Circuit Breaker

The ABB CB1-611R is a 22 mm signaling accessory for the CB1 automation family that provides both audible and visual alerts in control panels. It is designed to mount in 22 mm CB1 frames and combines a red light indicator with a built-in buzzer, operating on 110–130 VAC. Cataloged as 1SFA619600R6111, the CB1-611R is described in ABB literature as a signaling device (luminosa y sonora) for CB1 installations, and is listed by distributors such as Mouser and Rexel as a CB1-611R buzzer with red signaling. Typical applications include panel status indication, alarm signaling, and process alerts in industrial equipment, where immediate notification of faults or events is required. With its compact 22 mm footprint and CB1 compatibility, it complements other CB1 signaling options to deliver clear, reliable alerts in automation cabinets.
