The energy consumption limiter OM-611 is used for the automatic disconnection of the power supply of the circuit of the single-phase installation in case the specified power value of the receivers in the relay's measuring circuit is exceeded.

Operation

The limiter is adapted to operate with a power box, whose primary cycle is connected to the measuring circuit, allowing the control of circuits with any load capacity and setting the actual operating limit of the relay higher than 5A (IOM).

The measured current range depends on the box, e.g., from 5A to 50A at 10:1 for the 50/5A box. The current of the measuring input 4-6 should not exceed 5A. The relay's power supply is indicated by a green LED (U).

When the current in the measured cycle is less than the specified IOM limit, the contact is closed. Exceeding the specified limit in the measured cycle is indicated by a flashing red LED (I>). After the specified time, the Tdelay contact will open. The contact will automatically close after the specified Treturn time. If the current value in the measured cycle is still greater than the specified limit, the contact will reopen.
