The window/busbar-type terminals are located at the top and bottom, ensuring easy access with the busbar installed. The Z-HK and Z-NHK auxiliary contacts are mounted on the side, with contact position indication in red and green. It is suitable for use with conventional luminaires, with or without electronic ignition, up to 20 units per phase. The switch position and supply direction are arbitrary. The disconnection is independent of the mains voltage. The 4-pole switch can be used as a 3-pole switch with terminals 1-2, 3-4 and 5-6 (+ busbar bridge), or as a 2-pole switch with terminals 5-6 and N-N. Monthly testing is recommended by pressing the “Test” button, where the switch must trip. The test checks the disconnection due to leakage current and does not replace the measurement of the earth resistance RE and the insulation resistance of the conductors.
