GIRA Wireless Switch/Button Actuator Mini 1-Channel Potential-Free 542400

Controlling a light or small appliance wirelessly without running new cables can be a challenge in existing buildings. The GIRA 542400 solves this by providing a compact, potential-free switching actuator that installs in a standard flush-mounted box and communicates via the EnOcean wireless standard at 868.3 MHz.

Who is it for

Electricians and smart-home integrators who need to retrofit wireless control for lighting, fans, or other loads up to 10 A. It suits residential and commercial projects where wired bus systems are impractical.

Main features

• 1-channel potential-free relay output (dry contact) for flexible load switching.
• Operates on 230 V AC mains and switches up to 10 A resistive load.
• Supports incandescent lamps up to 2000 W, halogen 230 V up to 1000 W, and LED lamps under 20 W up to 400 W.
• Wireless communication via EnOcean protocol at 868.3 MHz, compatible with other EnOcean devices.
• Learnable for up to 35 universal pushbuttons and 10 direction pushbuttons.
• Switching functions include on/off, push-button, scene control, and central control.
• Flush-mounted installation in standard wall boxes; IP20 protection.
• Standby loss only 0.8 W; operating temperature from -20 °C to +50 °C.
• Short-circuit and overload protection built in.

Tips

For best wireless range, mount the actuator away from large metal objects and avoid placing it inside metal junction boxes. Pair it with EnOcean-compatible pushbuttons or sensors to create a complete wireless control system.
