to produce a latching of the output relay, so that it remains closed while the circulating current is over 200 mA. To use the
seal-in feature in the relay it is not necessary to configure any setting. It works, we only must program the corresponding
Circuit latching setting wiring the external circuit to terminals F34 and F36.
With this scheme, in the case of a failure to open from the breaker auxiliary contact, the F650 output relay does not open
the tripping coil current, as in this case the contact may be damaged, as it is prepared for opening currents around 0.35 A
at 125 Vdc. This latching or memory function is only guaranteed while the element is powered.
