Eltako FR12-230V

Field-free switch Self-learning field-free switch, interrupts the power supply after all downstream consumers and thus prevents disturbing electromagnetic fields, self-learning processor instead of setting buttons for the current thresholds, rated switching power 16 A/250 W AC self-learning field-free switch. Self-learning. Stand-by-loss only 0.8 Watt. Modern hybrid technology combines the advantages of wear-free electronic control with high switching power from special relays. The field-free switch interrupts the power supply after disconnection of downstream consumers and thus prevents interfering electromagnetic fields. Up to a current consumption of 200ma, small consumers are allowed which do not prevent field-free switching after larger consumers are switched off. The limit value does not have to be adjusted manually, but is learned by the FR12 using a patented method. Consumers with more than 200ma current consumption are always defined as consumers which are intended to cause the power supply to be switched on. As long as no larger consumer is switched on, the monitored circuit 1-pole remains switched off from the network. Neutral and protective conductors are not switched to prevent an antenna effect. An adjustable DC voltage with low residual ripple is present for monitoring. Therefore, a bridging of the working contact is not permissible and leads to destruction of the device. When a consumer is switched on, the field-free switch switches the monitored outer conductor with a delay of approx. 1 second and the LED lights red. Measurement voltage: 230 W
