ETI BE 220 modular buzzer for DIN rail, 220 V (2413001)

The ETI BE 220 modular buzzer is designed for installation in distribution boards on a DIN rail and serves as an audible signaling device in electrical circuits. It is used wherever it is necessary to generate a sound signal for switching events, state changes, alarms, or other events within the control scheme. Thanks to its modular format, the device integrates into standard shield assemblies alongside other rail-mounted equipment and does not require separate external mounting space. The model BE 220 is intended for a supply voltage of 220 V, which makes it suitable for use in AC networks with the corresponding rated voltage. This allows the buzzer to be applied in residential, commercial, and auxiliary electrical installations where audible indication is needed without additional complex signaling solutions. DIN-rail mounting simplifies installation in modular distribution boards and supports convenient layout of the electrical equipment inside the enclosure. According to the catalog classification, the product belongs to the group "Dzvinok ZE / Zumer BE, BEE" and the subgroup "Dzvinok/Zumer," confirming its function as an acoustic notification element. In a distribution board, this buzzer can be used to provide audible feedback for alarm conditions or service signals, as well as local notification for operators or users. It is especially relevant in control panels, automation systems, small distribution installations, and other electrical projects where a compact signaling module is required. The ETI BE 220 is part of ETI’s modular electrical equipment range and combines standard panel-format installation with sound signaling functionality. It is a practical choice when a clear audible alert is needed directly within a modular electrical panel, without the use of separate external signal devices.
