Three-phase device OM-310 was developed to measure electrical circuit parameters and protect consumers from surges.

Power limiter OM-310 is designed to:

• protect consumers from electric circuit malfunctions (power surges, phase loss, infringement of alternation and adhesion of phases, distortion of phase/line voltages)
• disconnect the load should it exceed a power consumption threshold until a user-specified time
• measure and display three-phase electric circuit parameters
• notify administrators of emergency situations
• remotely control loads via interface RS-232/RS485 or external switch

The device works with load capacities from 2.5 kW to 30 kW when using built-in current transformers and up to 350 kW when using external current transformers.
