1 normally open contact, not potential-free, 16A/250V AC, 230V LED lamps up to 600W, ESL up to 200W, incandescent lamps up to 2300W. Switch-off warning can be activated. Standby loss only 0.7 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. Contact switching at zero crossing to protect the contacts and lamps. The noiseless electronics do not bother the most sensitive ear - in contrast to many synchronous motors with mechanical gears. By using a bistable relay, there is no coil power loss and no heating as a result, even when switched on. After installation, wait for the automatic short synchronization before connecting the switched consumer to the mains. Control, supply and switching voltage 230V. Glow lamp current up to 50mA depending on the ignition voltage of the glow lamps. Precise time setting 1 to 12 minutes with minute scale. Separate permanent light switch with the large rotary switch. For 3-wire circuits with attic lighting, cannot be switched on later. Only for retrofitting existing systems. After a power failure, the lighting is switched on again if the time period has not yet ended. If the switch-off warning is activated, the lighting flickers starting around 30 seconds before the time period expires and a total of 3 times at increasingly shorter intervals.
