Why Choose the ABB TS 8/8 ES Bell Transformer?
The ABB TS 8/8 ES is an energy-saving bell transformer designed to supply safety extra-low voltage circuits for loads requiring discontinuous operation. As part of the ABB TS-ES series, it is particularly suited to doorbells, chimes and similar signalling equipment in residential and commercial electrical installations.
The TS 8/8 ES operates from a 230 V AC primary supply and provides an 8 V AC secondary output with a maximum rated power of 8 VA. Its secondary circuit provides SELV separation, while integrated thermal protection helps protect the transformer under overload and short-circuit conditions.
As an Energy Saving TS-ES model, the TS 8/8 ES is designed to reduce power losses compared with conventional TS bell transformers, with an off-load power loss of less than 0.8 W. Its compact two-module construction makes it suitable for integration into modular distribution boards and control enclosures.

Energy-Saving SELV Supply for Bells and Signalling Loads
Bell transformers provide electrical isolation between the mains supply and safety extra-low voltage equipment. The ABB TS 8/8 ES converts a 230 V AC primary supply to an 8 V AC SELV secondary supply, making it suitable for doorbells, chimes and other compatible loads requiring discontinuous operation.
ABB's TS-ES energy-saving range is designed to reduce transformer power losses by approximately 50% compared with the standard TS range. The TS 8/8 ES also incorporates a thermal protection device that 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.
- Other compatible discontinuously operated SELV loads.
