As the last resort I post the following question:
Preamble- I import some equipment from Holland which has a control panel configurable for single and three phase operation.
Originally the equipment was designed to cater to a load in the order of 3.5kW and therefore has three line filters rated at 20A each.
Filter capacitors ( 2 off ) are 22nF to ground from Line and Neutral.
These capacitors contribute to leakage current seen by a residual current device.
In single phase configuration all three EMI filters are connected in parallel and accordingly the leakage current is in the order of 6mA plus.
On a 10mA RCD ( which typically trips out on 8mA as an added safety feature ) additional 6 Ma causes a trip.
Filter has following markings
0.47uF ( X1 ) + 2x 22nF ( Y2 )
+2 x 1mH + 680kohm
and a graphic logo with a what looks like a stylised BK
Google search did not help
Does anybody recognise the part number/ source/ supplier?
