Electric motor                                                                                                    

3-phase squirrel-cage induction motor, 50 Hz.      Service factor 1.1. Class F insulation.    Motor rating P2 : 3.7 kW. 2 pol. Speed: 2860 rpm.    Nominal current 7.6A    

‍Starting method and motor protection                                                          

XJ 40 AT: Direct on line start (DOL 230-550 V) with built in AquaTronic unit, which automatically adjusts phase order by dual contactors, ensuring correct motor rotation. The AquaTronic unit monitors motor temperature, by use of NTC thermistors built into stator windings, and stops the motor at high temperature. It will also stop the motor at high amperage or if a phase is missing.  XJ 40: Direct on line start with built in contactor. Pumps to be used with VFD or 1000 V must have terminal block instead of contactor. Thermal switches (140 °C, ±5) built into the stator windings are connected to the contactor and stop the pump at high temperature.

‍Power cable‍
