Please can anyone help me to identify a capacitor.
It is fitted to an MK Sentry RCD socket, it is fitted in position C6 and is used as the mains dropper to power the RCD circuitry.
It's only markings are 334K250 on the top line and NIS~S82 on the bottom line.
The socket has an active RCD and the Reset button will not hold in. I think that not enough voltage is being applied to the circuit, because if I apply 18V dc to the circuit it will latch the solenoid, but out of the mains derived supply I am only getting about 10V.
TIA
