Why Choose the ABB BR12 12 V AC Buzzer?
The ABB BR12 is an electromechanical modular buzzer designed for clear acoustic signalling in residential, commercial and industrial electrical installations. Operating from a 12 V AC supply, it provides a straightforward low-voltage signalling solution for alarms, notifications, supervision systems and other applications requiring an audible indication.
The BR12 produces a buzzer sound level of approximately 70 dB at 0.6 m while consuming just 4 VA. It operates at 50/60 Hz and is intended for discontinuous operation, with ABB specifying a maximum permanent operating time of 15 seconds followed by a rest period of at least 60 seconds.
At only 18 mm wide, the BR12 occupies a single standard DIN module and can be installed in a flexible mounting position. Its IP20 protection rating, terminals accepting conductors up to 4 mm² and compliance with EN 62080 make it a practical acoustic signalling device for modular distribution and control equipment.

Compact Modular Acoustic Signalling
Modular buzzers provide an audible indication directly from electrical distribution and control equipment, making them useful for alarms, notifications and supervision functions. The ABB BR range is designed specifically for discontinuous acoustic signalling and includes versions for different supply voltages.
The ABB BR12 combines a 12 V AC operating voltage with a 70 dB buzzer signal and compact single-module construction. This makes it suitable where DIN-rail space is limited but an integrated audible notification is required within a compatible electrical installation.
Typical Applications
- Residential acoustic signalling circuits.
- Commercial building notification systems.
- Alarm indication.
- Electrical supervision and status signalling.
- Industrial acoustic notification.
- Schools, factories and other building installations.
- DIN-rail distribution and control panels.
- Compatible 12 V AC signalling circuits.
