Hi all
i am designing a 3phase(220V) sensing circuit. my circuit will be just sensing circuit it is passing 100mA maximum. kindly may you people tell the connector standard, or is this CTB93VE/4 connector is according to euro standard for 3phase.
 

That connector is only specified as good for 200V working voltage and you may have issues with creepage and clearance distances.
There really is not a standard for small three phase circuits within equipment except that whatever you pick must meet the LVD and any applicable product specific standards.

If I was doing it I would probably pick a 5mm or so pitch part (Apart from anything else terminating wiring into the mating half will be easier), and remember to fit circuit protection sufficient for the PSC (Which can be very large in three phase systems).

Regards, Dan.
 

if i use 5mm pitch 4pin connector then peak voltage difference between two line may reach to (440*1.414=622V). so what do u recommend whether it will follow all standards.
 

Required pin distance is a matter of applicable overvoltage category. If you review Phoenix Contact datasheets, you'll notice that the 5 mm connectors are qualified for 250 V working voltage, although they can be used for 400 V interphase voltage according to some standards. For 400 V, you better use 7.5 mm connector families.
