The relay power constraints OM-310

Limiter OM-310 Power is designed to:

• consumer protection with substandard electrical parameters of the network;
• full load shedding when power consumption exceeds the basic threshold specified by the user at the time;
• partial load shedding when power consumption exceeds an additional threshold to a user specified time;
• measure and display three-phase network parameters (operating values of the phase and line voltages;
• stresses positive, negative and zero sequences; operating phase currents; consumed by the load of active, reactive and apparent power, power factor phi);
• notification of emergency situations;
• remote connection and disconnection of the load on the RS-232 / RS485 or external switch.

A device designed to work with a load capacity from 2.5 kW to 30 kW using the integrated current transformers up to 350 kW with external current transformers, including in networks with isolated neutral.

Limiter OM-310 output provides the following consumer protections:

• when poor-quality mains voltage (harmful power surges, phase failure, phase sequence and violation of sticking phase distortion phase / line voltage);
• when exceeding a predetermined maximum current in any phase of the load;
  by leakage currents on the "ground".
