Device is designed for the protection of asynchronous electric motors with power from 2.5 to 315 kW.
Device is a DIN rail design.
UBZ provides permanent control of main voltage parameters and current values of the phase (line) currents, as well as controls the insulation resistance values of the electric motor.
Network voltage control (prevents unacceptable power surges, phase loss, infringement of alternation and adhesion of phases, distortion of phase/line voltages, reduction in the network frequency below the set value and/or increase of network frequency above given).
Mechanical overloads control (symmetrical overload in phase/line currents).
Protection at the minimum starting and/or working current.
