1 changeover contact potential-free 16A/250V AC, 230V LED lamps up to 200W, incandescent lamps 2000W. No standby loss. Modular device for mounting on DIN-EN 60715 TH35 mounting 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. Universal control voltage 8..230V UC. Low switching noise. Control display with LED. Integrated freewheeling/quenching diode (A1 =+, A2 =-). Safe separation according to VDE 0106, Part 101, therefore can also be used as a coupling relay. 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 commissioned and synchronizes when first activated. This relay is not suitable for feedback with the switching voltage of a dimmer switch. Only use the relays ESR12DDX-UC, ESR12NP-230V+UC or ESR61NP-230V+UC for this purpose. The electronics do not have their own power supply and therefore no standby loss. The microcontroller is only activated when the control contact is closed, which switches the bistable relay in the correct direction. When the control contact is opened or the control voltage drops, the relay switches back.
