## Summary description

DIN-rail circuit breaker ABB UD/S4.210.2.1 designed for 230 V installations, occupying up to 6 modular units. Compact white housing with dimensions 108 × 64 × 90 mm. Intended for overcurrent protection in residential and light commercial electrical panels. Supplied as a single unit, suitable for straightforward installation and modular distribution boards.

## Long description

Multichannel universal dimming actuator optimized for dimming retrofit LED lamps (LEDi) and compatible with incandescent lamps, low-voltage halogen lamps with conventional or electronic transformers, 230 V halogen lamps and dimmable energy-saving halogen lamps. The device features automatic load detection (which can be disabled), a separate neutral connection per channel and the option to connect outputs in parallel to increase total output power. Manual operation is possible on the device even without bus voltage or when unprogrammed; programming can also be performed without applied 230 V supply. The actuator includes an integrated bus coupler and offers extensive test and diagnostic functions for use with the i-Bus tool as well as fast parameter setting in ETS via copyable channel templates.
Advantages
Supports multiple lamp types including retrofit LEDi and conventional halogen; automatic load detection simplifies configuration while the option to deactivate it provides flexibility. Separate neutral per channel improves wiring options and safety. Parallel output connections allow scalable output power. Device supports manual control without bus power and can be programmed without main supply, and includes diagnostic functions for commissioning and troubleshooting.
Suitable for
Dimming retrofit LED lamps (LEDi)
Incandescent lamps and 230 V halogen lamps
Low-voltage halogen lamps with conventional (inductive L) or electronic (C/LC) transformers
Installations requiring scalable output power via parallel outputs
Key specifications
Supply voltage: 230 V~
Channels: multichannel universal dimming outputs
Minimum load: 2 W
Nominal power (incandescent/halogen): from 4×210 W/VA up to 1×600 W/VA depending on configuration
Dimmable LEDi trailing edge: 4×210 W/VA to 1×600 W/VA
Dimmable LEDi leading edge: 4×80 W/VA to 1×200 W/VA
Inductive (L) transformer support: 4×210 W/VA to 1×600 W/VA
Electronic (C) transformer support: 4×210 W/VA to 1×600 W/VA
Electronic LC transformer support: 4×80 W/VA to 1×200 W/VA
Separate neutral connection per channel
Integrated bus coupler and i-Bus diagnostic functions
How to use
Wire the actuator to a 230 V~ supply and connect lamp loads to the outputs, ensuring neutral is connected per channel as required. Configure parallel output connections where increased output power is needed, following the wiring rules for parallelized loads. Use the device front controls for manual operation if bus voltage is absent or the device is unprogrammed. Program parameters via ETS using channel templates or perform programming without applied mains if necessary. Use the i-Bus tool for testing and diagnostics during commissioning.
Usage recommendations
Use trailing-edge control for best compatibility with dimmable retrofit LEDi where supported; if lamps or transformers require leading-edge control, verify load ranges (minimum 2 W) and choose the appropriate control mode. Disable automatic load detection only if required by the installation. Ensure total connected load does not exceed the configured parallel-output rating.
