Power limiter OM-630 3ph 5-50kW multifunctional connection of priority and non-priority loads F&F EA03.001.007 Euroautomatika F&F

"OM" series power limiter Mounting on DIN-rail. For continuous monitoring of power consumed from the power supply network and disconnecting the load when it exceeds a set value, and protecting power circuits from short circuits. The limiter also protects power consumers (the load) from voltage surges occurring in 3-phase networks during a neutral wire break. The limiter monitors the voltage magnitude and the load current magnitude, calculates the power consumption value separately in each phase and processes these values according to the selected operating algorithm. When the power value increases above the set value, the load is disconnected from the network for a set time. After this time, it is automatically reconnected to the power supply. Features: three-phase; multifunctional; overcurrent protection; cyclic overload protection; protection against low and high voltage operation; protection during neutral wire break; selection of the method for determining the disconnectable power value: - total; - total, with power limitation in any of the phases at the level of 2/5P. supply voltage 3x(50...450) V AC; power control range 5...50 kW; contact - 2NO/NC (2x8 A).
