Table 3: Material code shaft seal
2.4 CURRENT
2.4.1 NOMINAL CURRENT
VMS 02A, 04A, 06A, 10A, 15A, 85A
The nominal allowable current of the motor is stated
on the motor plate. This shows the nominal working
range of the motor and can be used to protect the
motor.
Measuring the actual current of the pump during
operation can be used to pre-set the motor protection
switch to protect the pump/motor combination.
This current value can also be used to determine the
proper electrical equipment such as variable
frequency drive, main switch, wiring diameter etc.
WARNING
Not only the motor, but also the pump has
to be protected in its application.
2.4.2 MAXIMUM CURRENT
VMS 32A, 45A, 65A
The maximum allowable current of the motor is men-
tioned as I.max. on the motor plate. This maximum
allowable current shows the maximum working range
of the motor and can be used to protect the motor.
WARNING
Be careful in using it this way, because, not
only the motor, but also the pump has to be
protected in its application.
On the pump plate (sleeve sticker) this "pump current
at 400 Volts" will be mentioned as I nom. and can be
used to pre-set the motor protection switch to protect
the pump/motor combination.
