Eltako 21100801 ESW12DX-UC with tungsten pre-contact. Electronic impulse switch

1 normally open contact, potential-free 16A/250V AC with tungsten pre-contact, 230V LED lamps up to 600W, incandescent lamps 3300W. Max. inrush current 500A/2ms. No standby loss. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. With the patented Eltako Duplex technology (DX), the normally potential-free contacts can still switch at zero crossing when switching 230V AC 50Hz, thereby drastically reducing wear. To do this, simply connect the N conductor to terminal (N) and L to 1 (L). This results in a standby loss of just 0.1 watt. Universal control voltage 8..230V UC. Low switching noise. No constant power supply required, therefore no standby loss. By using a bistable relay, there is no coil power loss and no heating as a result, even when switched on. The relay contact can be open or closed when started up and synchronizes when first activated. The electronics do not have their own power supply and therefore do not consume any power in either contact position. The control current, which activates the microcontroller, only flows during the short control pulse of just 0.2 seconds. It reads the last switching state from its non-volatile memory, switches the bistable relay in the opposite direction accordingly and writes the new switching state back into the memory.
