Electrical data: single-phase motor

When you start a cold pump, the motor draws the start-up current shown in
prevent unnecessary fuse failure during start-up use a slow-blow fuse. Within five minutes, as the oil in the pump
warms up, the start-up current reduces to the full-load current specified in

Electrical data: three-phase motors

Refer to the data in Table
range electrical supply: refer to the diagram specified in
highest of the selectable voltages.
When you start a cold pump, the motor draws the start-up current listed in
five minutes, as the oil in the pump warms up, the current drawn slowly reduces to the full-load current specified in
Table 2.
When you restart a hot pump, the motor draws the start-up current specified in
current drawn then immediately falls to the full-load current value.
