1 non-potential-free switch 16A/250V AC. 230V LED lamps up to 200W, incandescent lamps 2300W. Self-learning. Standby loss only 0.8 watts. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high switching capacity of special relays. The field disconnector interrupts the power supply after the shutdown of downstream consumers, thereby preventing disturbing electromagnetic fields. Small consumers with a current draw of up to 200mA are allowed, which do not prevent the field disconnection after larger consumers are switched off. The threshold does not need to be set manually but is learned automatically by the FR12 using a patented method. Consumers with a current draw of more than 200mA are always defined as consumers that should trigger the connection of the mains voltage. As long as no larger consumer is switched on, the monitored circuit remains disconnected from the mains in a single-pole manner. Neutral and protective conductors are not switched to prevent an antenna effect. A low ripple adjustable DC voltage is present for monitoring. Therefore, bridging the working contact is not permitted and will lead to the destruction of the device. When a consumer is switched on, the field disconnector reconnects the monitored phase with a delay of about 1 second, and the LED lights up red.
