Why Choose the ABB TS8/8 Bell Transformer?
The ABB TS8/8 is a compact modular bell transformer designed to supply safety extra-low voltage circuits for loads requiring discontinuous operation. As part of the ABB TS series, it is particularly suitable for doorbells, chimes, buzzers and other low-voltage signalling equipment in residential and commercial electrical installations.
The TS8/8 operates from a 230 V AC primary supply and provides an 8 V AC SELV secondary output. With a maximum rated power of 8 VA, it provides electrical isolation and a dedicated low-voltage supply for compatible signalling equipment.
The transformer incorporates a thermal protection device in the secondary circuit, helping it withstand overload and short-circuit conditions. Its compact 35 × 85 × 65 mm construction and two-module width make it suitable for integration into modular distribution boards and other DIN-rail electrical assemblies.

Reliable SELV Power for Bell and Signalling Circuits
Bell transformers provide electrical isolation between the mains supply and safety extra-low voltage equipment. The ABB TS8/8 converts a 230 V AC primary supply into an 8 V AC SELV output, making it suitable for doorbells, chimes and other compatible signalling loads requiring discontinuous operation.
ABB TS transformers incorporate a thermal protection device in the secondary circuit and are classified as non-inherently short-circuit-proof bell transformers. The protection automatically allows operation to resume after the transformer has sufficiently cooled or the overload condition has been removed.
Typical Applications
- Residential doorbells.
- Door chimes and buzzers.
- Low-voltage signalling circuits.
- Residential distribution boards.
- Commercial building electrical panels.
- Compatible discontinuously operated SELV loads.
