Old Siemens datasheet needed

[Denan]

Hello,

I am trying to find datasheet of an old Siemens vacuum contactor: 3TL 5100-1F 400A
And / or
Resistor: Siemens 470 Ohm, 110V 3 Ty S325-0E

Attached is connection diagram. Actually, I am trying to find power rating for those two resistors, I need to replace them. Voltage between terminal 37 and 48 is 110VDC.

Anyone who had any data for this? I have tried Siemens site but can not find anything there as these are very old components.

You will never need more than 25 watts. That is what each of them dissipates continuously if the coil resistance is zero ohms - which it probably isn't.

If there's room for 25 W resistors, use that rating. If not, measure the coil resistance and calculate power needed.

Half full - Half empty? I don't mind. It's what in it that counts.

Did you check this?

Thanks for replays! I found a resistor with 50 W, so think we go for that. Space in the cabinet is not a problem.

Yes I have found that at Siemens but those are newer models so I thought they are different.
Assume that those resistors are not neded for new types. Am I right?

One more question:

- the capacitor shown in the circuit har this data:
1µF +/-10%
1kV
B25351-J1105-K000

I need to replace it as well. Found something here:

but I am not sure if I can use one of these since they are all for AC voltage while my circuit has 110VDC.

Any suggestions?
