1SFA619600R6336

The ABB 1SFA619600R6336 CB1-633B Compact Buzzer is an industrial audible signalling device designed to provide clear pulsating sound alerts in electrical control panels, industrial machinery, and automation systems. Operating at 230V AC, 50/60 Hz, this buzzer produces an intermittent audible warning to notify operators of equipment faults, machine operating conditions, and process alarms.

Part of ABB's Compact Pilot Devices range, the CB1-633B features a black non-illuminated front, integrated sound-generating mechanism, and compact construction suitable for standard 22 mm panel mounting. Its pulsating sound helps distinguish warning signals from continuous audible indicators, making it suitable for industrial fault notification and equipment monitoring.
