OWEN UZOTE-2U Three-phase motor protection device

The UZOTE-2U three-phase electric motor protective shutdown device is designed to protect asynchronous electric motors by shutting them down in the event of the following emergency: power supply phase break or phase imbalance, electric motor rated current exceeded, stator winding overheating. If the insulation of the stator winding is broken, the start of the electric motor is blocked. The device is used in control circuits of electric motors switched on by magnetic starters or contactors of 0 ... V with switching coils for voltage from 220 to 380 V with a frequency of 50 Hz. Specifications Supply voltage of the device 190...240 V Power consumption, not more than 5 W Power of the protected electric motor 1.6...160 kW Permissible load current on the contacts of the built-in e/m relay 1.5 (2.5) A at 220 V Time to prepare the device for operation no more than 10 s Maximum line length: - between the device and the temperature sensor (with a line resistance of not more than 5 Ohm) no more than 300 m - between the device and transformer current sensors no more than 15 m Motor protective shutdown temperature from 80 to 90 °С Device response time: – in case of phase failure 4...12 s – in case of current overload by 1.5 times 30...60 s – in case of current overload by 4 times 8...24 s case dimensions130*105*65 mmCase protection degreeIP44Operating conditionsAmbient air temperature from plus 5 to plus 50 °C Atmospheric pressure from 86 to 106.7 kPa Relative air humidity (at 35 °C) from 30 to 80% Package contents Device UZOTE-2U resistance Set of fasteners type H Current transformer - 3 pcs.
