OM-110 power limiting relay is used for continuous control of single phase active or total power. The measured power range is between 0 and 20 kW or between 0 and 20 kVA OM-110 rejects the load in case the user-set maximum allowed load consumption power level is exceeded (with a set rejection time), and subsequently activates the load automatically (with a set activation delay time, or an option to block reclosing).
Potentiometers and DIP-switches installed in the front panel allow the user to set the following values:
The load consumption is measured without electrical opening, using an integrated current sensor.
OM-110 relay can be used in the following capacities:

*In the extreme right position of the knob, turn-off time of 295 s is allowed. **Reaction time on turn ON is not more than 2 seconds. This time includes device selftesting, turning ON the power load, measuring power consumption and tripping the power load OFF in case fault situation is detected. *** To increase operational range to low voltage ОМ-110 has function to disable LED digital indicator if voltage level gets lower than 130V. If voltage level is less than 110V then OM-110 automatically opens its output terminals to initial cold state position and thus tunrs OFF. |

OM-110 complies with requirements IEC 60947-1, ІEC 60947-6-2, CISPR 11, IEC 61000-4-2.
Harmful substances in concentration more than allowed are absent.
