White Electric | Single Switch Socket Outlet, 250V, 10A, Standard Size, Vertical

It is not possible to perform this application and connect secondary P5 VT directly on lines 415/240.

As per P5 documentation, even though the secondary setting VT range is 25/250 V, the voltage withstand is only 276 Vac.


And P5 is not designed for a direct VT scheme, and they have to add an interposing VT.

Issue:

Can use the 2P iC60 (N or H) MCB for 400V application measuring 400V across phase to Neutral?

Product Line:

Acti 9

Environment:

iC60 (N or H)

Resolution:

Yes, MCBs Acti9 iC60N/H 2P can be used under Ue (Ph/N) or (Ph/Ph)=400Vac applications.
You can refer to breaking capacities declared in catalogue pages for Ue=380-415Vac (e.g Icu=10kA for iC60N 2P C 40A including ref.A9F44240).

The alternative replacement for NS630H with STR23SE trip unit is the new offer Compact NSX new Generation C63H32D630.

Issue:
N/A

Product Line:
Altistar 48

Environment:
Altistart 48

Cause:
N/A

Resolution:
ATS48 has a control supply and a power supply.

On  the Y range, you have a control supply that is 110-220 and the power supply is 208-690V. Y range is dedicated for the US market, with NEC standard soft starter that must be protected against the current unbalance.  Y range has three current sensors,. There are only 2 on the Q range (one more OLF on the Y range).

On Q range, the control supply is 220-415V and the power supply is 230-415V.
 

The maximum output voltage of ATV drives are the same as the output voltage of the input voltage.

ATV320 can take maximum 240VAC single phase.

It can accept 240VAC max single phase input, however, it cannot output voltage greater than 240VAC. Therefore, if the voltage is rate 415V in Y connection, it will not be able to reach its full voltage, therefore, the motor would not be able to reach full speed at full load, please consider delta connection.

ATV600 can take maximum 480 VAC Single-phase
https://www.se.com/ww/en/download/document/EAV64300/
We may use transformer on the input of 240VAC single phase input, and boost the voltage to 480VAC single phase and feed to VSD. The drive in this case will be able to reach nominal voltage of the motor, however, this is only for pump application and de-rating is required, please see the above link for detail.

No ATV900 Process drives are approved for single phase supply.  They are designed strictly for 3 phase input power to run a 3 phase motor.

Issue:
Reference point for the 24V power supply.

Product Line:
Altivar VFD

Environment:
All models and serial numbers with the exception of the ATV11.  (The ATV11 has a control voltage of +15V.)

Cause:
None

Resolution:
Yes, the common (COM) terminal of the Altivar power supplies are floating (no connection to earth ground) so the voltage measured to the 24v from the earth ground can be different from the COM terminal.
