GIRA Switching Actuator 4-Gang DIN Rail KNX/EIB 16A C-Load 104500

Managing multiple lighting circuits or loads in a KNX building automation system often requires separate actuators, adding complexity and cost. The GIRA Switching Actuator 4-Gang DIN Rail KNX/EIB 16A C-Load 104500 consolidates four independent switching channels into one compact module, simplifying installation while delivering robust performance for resistive, inductive, and capacitive loads. Its C-load capability ensures reliable switching even with challenging loads like LED drivers or fluorescent ballasts.

Who is it for

This actuator is ideal for electricians, system integrators, and building automation professionals who need a dependable, space-efficient solution for controlling lighting, heating, or other electrical loads in residential or commercial KNX installations. It suits projects where DIN rail space is limited but high switching capacity is required.

Main features

• Four independent switching outputs, each rated at 16 A (AC1, C-load) for versatile load handling.
• Supports resistive, inductive, and capacitive loads, including LED lighting and electronic ballasts.
• Manual operation via push buttons and clear LED status indication for easy commissioning and troubleshooting.
• Compact 4 TE (72 mm) DIN rail housing saves valuable distribution board space.

Tips

When installing, ensure the actuator is mounted in a distribution board with adequate ventilation and that the load current does not exceed 16 A per channel. Use the manual push buttons during commissioning to verify wiring before downloading the KNX application. For capacitive loads, consider derating if multiple channels are used simultaneously at high ambient temperatures.
