Product Description

UBZ***1 (*****0A) UNIVERSAL INDUCTION MOTOR PROTECTION UNIT CONTROLS DESCRIPTION AND DIMENSIONS DIAGRAM 1. Control for nominal current setting, Inom; 2. Control for operating current setting, Iop (± % Inom); 3. Control for T2 (double overload trip) delay setting; 4. Combined trip adjustment control for Umin/Umax; 5. Control for phase imbalance adjustment, PI; 6. Control for trip threshold for the minimum current, Imin (%Inom); 7. Control for automatic reset delay setting, Ton; 8. Green LED indicating for the mains voltage presence; 9,*0,*1. Red LEDs indicating faults for insulation, overload and U fault respectively; *2. Green LED indicating for load energization; *3. Output terminals; *4. Input terminals (*0,*1,*2 are used for the connection with the BO**1 exchange unit); *5. Insulation monitoring terminal. Applications The UBZ***1 *****0A universal induction motor protection unit is designed for the continuous monitoring of the mains voltage parameters and for RMS phase/line currents of *-Phase AC **0V/*0Hz electrical equipment monitoring, primarily, of induction motors whose power is from *0kW up to **5 kW, isolated neutral system included. The unit provides full and effective protection of electrical equipment by a magnetic starter (contactor) coil control. The unit isolates electrical equipment from the running system and/or disables its start. This is performed in the following cases: 1. when the mains voltage is of poor quality (unallowable voltage jumps, phase loss, incorrect phase sequence and phase «coincidence», phase/line voltage imbalance); 2. when mechanical overloads (symmetrical phase/line current overload) take place. The unit performs overload protection with a dependent time delay; 3. when phase/line current asymmetrical overloads induced by faults inside the motor occur.
