Detailed Product Description
The UBZ-301 universal electromotor protection unit belongs to the new generation of electromotor protection devices. Application of modern microprocessor-based technology allows to provide the necessary unit operation logic that no protection devices of domestic and foreign production can support. The UBZ is a conceptually new device that provides full and effective multi-fault protection (protection from all faults in the mains, motor performance-induced faults and internal fault conditions of motor) for 3-Phase AC motors by a magnetic starter (contactor) coil control. The unit is designed for the continuous monitoring of the mains voltage parameters and for RMS phase/line currents of 3-Phase AC 380V/50Hz electrical equipment monitoring, primarily, of induction motors that develop power from 2.5kWT up to 315 kW, isolated neutral system included. It offers a solution for an electric motor heat balance equation.
