Why Choose the ABB TS244812 TS24/4-8-12 Bell Transformer?
The ABB TS244812 (TS24/4-8-12) is a compact 24 VA bell transformer designed to provide safety extra-low-voltage power 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 electrical distribution boards.
Operating from a 230 V AC primary supply, the TS24/4-8-12 provides selectable 4 V AC, 8 V AC and 12 V AC SELV secondary outputs. Its 24 VA maximum rated power is intended for discontinuously operated loads, providing flexibility for bell and signalling equipment requiring different extra-low-voltage supply levels.
The TS24/4-8-12 is a non-inherently short-circuit-proof bell transformer with an integrated thermal protective device that helps protect the transformer during overload and short-circuit conditions. Its compact 52.5 × 85 × 65 mm construction and multiple secondary voltages make it a versatile choice for modular low-voltage signalling installations.

Flexible Extra-Low-Voltage Power for Bell and Signalling Circuits
Bell transformers electrically separate mains voltage from extra-low-voltage signalling circuits, providing a suitable supply for compatible doorbells, chimes, buzzers and similar equipment. The ABB TS range is designed for discontinuous loads and incorporates thermal protection to help the transformer withstand short-circuit and overload conditions.
The ABB TS24/4-8-12 combines a 230 V AC mains input with selectable 4 V AC, 8 V AC and 12 V AC outputs. This multi-voltage capability allows one transformer to support a variety of compatible signalling devices, while its 24 VA maximum rating and DIN-rail construction provide a practical solution for modular electrical installations.
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 4 V AC, 8 V AC or 12 V AC loads.
