230V supply voltage and switching voltage.
State-of-the-art hybrid technology combines advantages of nonwearing electronic control with
high capacity of special relays.
The FR61-230V mains disconnection relay disconnects the power supply once all series
connected loads are turned off, thus preventing any electromagnetic interference fields from
occurring.
Small loads up to 20 mA are acceptable and, once major loads are disconnected, they do
not prevent field disconnection. There is no need to manually set the limit; it is learned by the
FR61. Loads drawing more than 200 mA are consistently defined as loads which should cause
the line power to be connected.
As long as no major load is turned on, one pole of the monitored circuit remains isolated from
the mains. Neutral and earth are connected continuously to avoid acting as an aerial.
A DC voltage of 230 V DC with an extremely low residual ripple is applied for monitoring.
Therefore, it is prohibited to bridge the relay contact, which would ultimately cause device
failure.
When a load is turned on, the mains disconnection relay connects the phase.
If the phase is switched on for the first time and after a power failure the FR61
automatically learns in again: At first an inrush current of 30 mA is specified. If a new small
load is switched on for more than 24 hours, the total current drawn by the monitored circuit is
less than 200 mA, and in the meantime the light has been switched on and off, the new load
is learned in and the conductor is switched off. This learn-in mode can be realised immediately
after connection of the new load by briefly switching off the MCB.
