1 normally open contact, not potential-free, 16A/250V AC, 230V LED lamps and ESL up to 100W, incandescent lamps up to 2000W, without switch-off warning. Standby loss only 0.7 watts. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. The noiseless electronics do not bother even the most sensitive ear - in contrast to many synchronous motors with mechanical gears. Control, supply and switching voltage 230V. Time setting approx. 0.2 to 12 minutes. Glow lamp current up to 50mA, depending on the ignition voltage of the glow lamps. Own permanent light switch with the large rotary switch. For 3- and 4-wire circuits, can be switched on later, with attic lighting for 4-wire circuits. Automatic detection of the circuit type. Without switch-off warning and contact switching at zero crossing. With double connections for button and lamp, so that connection can be made either at the top and bottom or only at the bottom.
