Hager SU213 Modular Bell 230V AC 0.03A 1-Module DIN Rail with Continuous Tone

In residential and light commercial electrical installations, a reliable audible signal for doorbells, buzzers, or alarm notifications is essential. The Hager SU213 modular bell provides a clear continuous tone at 80 dB, making it suitable for hallways, workshops, or offices where a distinct call signal is required. Designed for DIN rail mounting, it integrates seamlessly into distribution boards alongside other modular devices.

Why choose it

The SU213 combines robust construction with straightforward installation. Its compact 1-module design saves space in the distribution board, while screw terminals ensure secure wiring. The continuous tone is easily distinguishable from other signals, reducing confusion in multi-occupancy buildings. Compliance with EN 60669-1 guarantees safety and performance.

Ideal use cases

• Doorbell signalling in residential flats and houses
• Audible alarm indication in small commercial premises
• Call notification in workshops or service areas
• Integration into existing 230V control circuits

Good to know

The bell is rated for indoor use only (IP20) and should be installed in a protected environment. It operates directly from the 230V mains without a transformer, simplifying wiring. For multiple bells or extended wiring runs, ensure the total current does not exceed the rated 0.03 A. The light grey housing blends with standard electrical panels.
