Potential-free relay 16A/250V AC, 230 V LED lamps up to 600W, incandescent lamps 2000W. No standby loss. Modular device for mounting on DIN rail EN 60715 TH35. 1 division unit = 18mm wide, 58mm deep. With the patented Eltako duplex technology (DX), the normally potential-free contacts can still switch at zero crossing when switching 230V AC 50Hz, thus drastically reducing wear. Simply connect the neutral conductor to terminal (N) and live to terminal 1(L). This results in a standby loss of only 0.1 watts. If the contact is used to control devices that do not switch at zero crossing themselves, (N) should not be connected, as the additional closing delay would have the opposite effect. Control voltage 110V AC - 240V AC at control input A1/A2. Very low switching noise. No constant power supply required, therefore no standby loss. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. By using a bistable relay, there is no coil loss and no heating even in the switched-on state. The relay contact can be open or closed at startup and will synchronize on the first actuation. The terminal assignment is identical to the electromechanical impulse switch S12-100-. If this impulse switch is in a circuit monitored by a field disconnector, no additional basic load is required. However, the monitoring voltage must be set to maximum, and control is only via A1-A2.
