Eltako FR61-230V Mains disconnector Nominal voltage: 230 V Switching current (max.): 10 A 1 pc(s)

Self-learning field isolator 230V. 1 NO contact non-potential-free 10A/250V AC. Stand-by loss only 0.8 Watt. For panel mounting. Built-in device 45mm long, 45mm wide, 26mm deep. Supply and switching voltage 230V. The latest hybrid technology combines the advantages of wear-free electronic control with high switching capacity of special relays. The FR61-230V field isolator interrupts the power supply after switching off downstream consumers and thus prevents interfering electromagnetic fields. Up to a current consumption of 20mA, small consumers are permitted, which do not prevent field activation after switching off larger loads. The limit does not have to be set manually, but is learned from the FR61. Consumers with more than 200mA power consumption are always defined as consumers, which are supposed to cause the mains voltage to be switched on. As long as no larger load is switched on, the monitored circuit 1-pole remains switched off from the mains. Neutral and earth conductors are not switched to prevent an antenna effect. A DC voltage of 230V DC with low ripple is applied for monitoring. Therefore, bridging the working contact is not permitted and will destroy the device. When a load is switched on, the field isolator switches on the monitored external conductor. When the external conductors are switched on for the first time and after a power failure, the FR61 automatically learns anew: First, an inrush current of 30mA is specified. If a small consumer is then switched on for more than 24 hours, the total current consumption of the monitored circuit less than 200mA and has been switched on and off in between, this small consumer is trained and the conductor is switched off. By briefly switching off the relevant circuit breaker, this learning phase can also be initiated immediately after connecting a new small consumer.
