The Gira Switching Actuator, 2-gang 16 A with Manual Operation (1040 00), is a KNX actuator intended for switching electrical loads through two output channels. It receives control telegrams over KNX TP and operates the connected circuits according to the commissioned ETS parameters. The integrated manual operation feature can be useful during installation, testing or troubleshooting when local switching is required. The product is suitable for building automation designs that need KNX-controlled on/off switching, but load compatibility and switching limits must be checked for the specific application. Before selection, review the manufacturer’s ratings for load type, inrush current, protection and wiring, and confirm the current ETS application and installation instructions.
