2CSM081012R0811 ABB TS8468SW TS 8/4-6-8SW Bell Transformer 8 VA

Why Choose the ABB TS8468SW Bell Transformer?

The ABB TS8468SW, also designated TS 8/4-6-8SW, is a compact 8 VA bell transformer designed to provide safety extra-low voltage (SELV) for doorbells, chimes and other loads requiring intermittent low-voltage power. As part of the ABB TS series, it provides selectable 4 V, 6 V and 8 V AC secondary voltages from a 230 V AC primary supply.

Designed for modular electrical installations, the TS8468SW mounts on a DIN rail for convenient integration into distribution boards and control enclosures. Its multiple secondary-voltage options allow one transformer to support a range of compatible low-voltage signalling equipment.

With a maximum rated power of 8 VA, a 230 V AC primary voltage and selectable 4/6/8 V AC outputs, this transformer provides a practical solution for bell and signalling circuits. The SW version also incorporates a 0-1 switch for local switching.

Reliable Low-Voltage Supply for Bell and Signalling Circuits

Bell transformers reduce mains voltage to a safety extra-low voltage suitable for equipment such as doorbells and chimes. The ABB TS series is intended for loads requiring an intermittent supply, providing electrical isolation and convenient low-voltage outputs for building electrical installations.

The TS8468SW offers three secondary-voltage options from a single modular transformer, allowing installers to select 4 V, 6 V or 8 V AC according to the connected equipment. Its DIN rail format and integrated switch make it well suited to installation alongside other modular protection and control devices.

Typical Applications

• Doorbell and bell circuits.
• Electrical chimes and signalling devices.
• Low-voltage calling systems.
• Residential and commercial distribution boards.
• Building electrical installations.
• Intermittently operated SELV loads.
