Why Choose the ABB TS168 TS16/8 Bell Transformer?
The ABB TS168 (TS16/8) is a compact 16 VA bell transformer designed to provide a safety extra-low-voltage supply for bells, chimes and compatible signalling circuits. Part of the ABB TS / System pro M compact range, it combines electrical isolation with a modular DIN-rail format for straightforward integration into residential and commercial distribution boards.
Operating from a 230 V AC primary supply, the TS16/8 provides an 8 V AC SELV secondary output with a maximum output current of 2 A. Its 16 VA maximum rated power is intended for discontinuously operated loads such as doorbells and signalling devices where a safe extra-low-voltage supply is required.
The TS16/8 is a non-inherently short-circuit-proof bell transformer equipped with a thermal protective device that automatically resets after the transformer has cooled sufficiently or the overload has been removed. Designed in accordance with EN 61558-1 and EN 61558-2-8, its compact 35 × 85 × 65 mm construction makes it well suited to modular electrical installations.

Safe Extra-Low-Voltage Power for Bell and Signalling Circuits
Bell transformers electrically separate the mains supply from extra-low-voltage signalling circuits, providing a suitable power source for compatible doorbells, chimes and similar equipment. The ABB TS range provides a SELV secondary supply and is designed for applications where the connected load operates discontinuously rather than requiring continuous transformer output.
The ABB TS16/8 combines a 230 V AC mains input with a dedicated 8 V AC secondary output, 16 VA maximum rated power and up to 2 A output current. Its automatic-reset thermal protection and compact modular construction make it a practical solution for bell and signalling circuits installed within DIN-rail distribution equipment.
Typical Applications
- Residential doorbell circuits.
- Electric chimes and buzzers.
- Low-voltage signalling equipment.
- SELV bell circuits.
- Door-entry signalling installations.
- Residential and commercial distribution boards.
- Compatible intermittently operated 8 V AC loads.
