Comat AC Current monitoring relay

The EOCR-AR provides for the monitoring of overcurrent on AC power circuits, the EUCR-BR for undercurrent. One or two current paths can be monitored directly up to 60(75)A, by means of the integrated current loop transformers. The adjustable alarm delay (to) and the automatic alarm resetting (tr) permit universal usage in motor and transformer protection systems, in the monitoring of electrical heating elements and in the control of pumps, ventilation systems, suction and feed devices. The nominal monitoring range in the three types -05/-30/-60 can be altered by multiple looping of the conductor.
