Title: Finder Type 20.21 Relays
Post by: Lt403 on January 16, 2025, 01:38:14 pm

Hi everyone,

Are all of these relays the same on our coach?

The one for the Gen keeps on tripping, it's original, and I'd like to replace it.
Both relays in the HWH compartment have the same marking.

These relays don't seem to be available without ordering them.

Thanks

Thanks,
Had seen that on the picture it showed 24V so thought that wasn't it. When you read the specs it says 12V.

The part number on the amazon link is correct, but the picture shown is the AC version not the DC version. I'd be leery of ordering that as you really don't know what you will get.

I would just order what you need from Digikey or Newark .. look for 20.21.9.012.xxxx 9 means DC / 012 is the 12v version

Attached the datasheet

Thanks Steve,
I'm planning on switching the one under the floor in my closet that controls the light with the one in the "control box " of the generator which keeps on tripping if the numbers are the same.

Try to space them apart a little. They will last longer
