current will then 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
When you start a warm pump, the motor will draw the start-up current shown in
current drawn will then immediately fall to the full load current specified in
Electrical short-circuit and ground-fault protection of the pump will be provided by fitting Class CC fuses of the values
