Starting Method and Motor Protection

XJS 50 AT: Direct on line start (DOL 500-550 V) with built in AquaTronic unit, which automatically adjusts phase order by dual contactors, ensuring correct motor rotation.
Soft start is built in with the AquaTronic unit at 230-400 V, where three thyristors reduces start current to three times the nominal current. Here two relays ensure 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.

XJS 50: 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 ºC, ±5) built into the stator windings are connected to the contactor and stops the pump at high temperature.
