Power consumption limiters OM-611

Power consumption limiters OM-611


With adjustable actuation and return time. For cooperation with a current transformer.
Power consumption limiters OM-611 is devised for the automatic disconnection of power from the circuit of single-phase wiring systems once the rated power consumption of the receivers incorporated into the system is exceeded.

The relay is designed to cooperate with current transformers, whose input is included in the circuit controlled, and output to measuring contacts OM, which allows you to control the circuits of any load and set the  actual actuation threshold of the relay higher than 5A (IOM). The range of the measured current  will be dependent on the transmission of relay e.g. from 5A to 50A with the transmission 10:1.

Current input 4-6 relay does not exceed 5A.

The power supply of the relay is indicated by the green LED (U). When the current in the measured circuit is lower than the set threshold of IOM switch, the contact will remain closed (position 7-10). Exceeding the set threshold in the measured circuit is indicated by the pulsating red LED I>. After a preset time Tdelay, the contact is opened (position 7-12). The contact will be closed automatically after the preset time Treturn. If the value of the current in the measured circuit will still be higher than the set threshold, the contact will re-open.
