Harmony Control. This current monitoring relay has an integrated current transformer so that the line to be monitored is detected without contact. To do this, the line must be fed through the hole in the transformer. The adjustable current limit value of 2-20 A is also monitored for exceedance. A relay changer is available for reporting, which can be loaded up to 5 A. The function of the output relay can be inverted using a wire bridge. Two LEDs show the status. The width is 17.5 mm and it is mounted on the top hat rail. Supply voltage 24-240 VAC/DC (50-60 Hz).
