Electrical data: three-phase pumps

The dual-voltage, dual-frequency motor is designed for a three-phase electrical supply and is suitable for 50 Hz or
60 Hz operation. The motor can be manually configured for nominal supply voltages of 220–240 V or 380–460 V (refer
to Section 3.7.1). Pumps are supplied preset for nominal 380–460 V electrical supplies.
When a cold pump is started, the motor will draw the start-up current shown in
current will then reduce quickly as the motor reaches the rated rotational speed. Within 5 minutes, as the oil and
pump warms up, the current drawn will slowly reduce to a maximum of the full load current specified in
When a warm pump is started, the motor will draw the start-up current shown in
current drawn will then immediately fall to the full load current.
Electrical short-circuit and ground-fault protection of the pump will be provided by fitting appropriate pre-approved
branch circuit protector or Class CC fuses of the values shown in
