1SFA619600R6316

The ABB 1SFA619600R6316 CB1-631B Compact Buzzer is a reliable industrial audible signaling device designed to provide pulsating sound alerts in electrical control panels, industrial machinery, and automation systems. Operating at 110–130V AC, 50/60 Hz, this buzzer produces an intermittent audible warning to notify operators of equipment faults, machine conditions, and process alarms.

Part of ABB's Compact Pilot Devices range, the CB1-631B features a black non-illuminated front, an integrated sound-generating mechanism, and compact construction suitable for standard 22 mm panel mounting. Its pulsating sound helps distinguish warning signals from continuous alarms, making it suitable for machine fault notification, equipment monitoring, and industrial control-panel signaling.
