4.6.1 Electrical data: three-phase pumps

When you start a cold pump, the motor will draw the start‑up current shown in
Electrical data (three
reduce quickly as the motor reaches rated rotational speed. Within 5 minutes, as the oil and
pump warms up, the current drawn will slowly reduce to the full load current specified in

then immediately fall to the full load current specified in
pumps)
Electrical short‑circuit and ground‑fault protection of the pump will be provided by fitting
Class CC fuses of the values shown in
at the point of connection to the supply. If these are not available in your country of use,
Type aM European fuses of the same rating can also be used.
