2.3 Current
2.3.1 Nominal current
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.
2.3.2 Motor protection
Standard single phase motors are delivered including motor protection. The motor protection is provided either by a thermal circuit breaker or by a motor winding protection.
Please contact your supplier for more detailed information about your motor protection.
