Good Quality Low Price option for 24V upto 200A Bus Bar (no problem finding 12V)?

Any one used an affordable 24V for 200A bus bar? (No problem finding 12V, but no low cost 24V). Any pointers will be appreciated.

Found very good price on amzn.com, but different responses as the spec sheet says 12v, whereas a user says 24v works fine. No response from seller, of course.

Unless the Bus Bar has some sort of switching incorporated in it then I can't think why it would be limited to 12V and not be able to safely work on 24V systems.
Does it have fuses with it? These could have a Voltage rating, but should be fine up to 24V.
Do you have a link to the product that you can share with us?

Strictly a passive bar. Not sure why the spec would be 12V and bolt connector is rated for 24V. Never heard from the seller. Users all (except one) say they would only use it for 12V cause that's the spec. One said she's using it for 48V without problems.

Course I'm sure the seller is just a reseller and has no clue -- as I got no response from him/her.

Blue is 3 times the price.

bluesea makes busbars that they rate to 48VDC. If its purely passively with only the conductor and connection points, agree that "up-rating" to 24VDC is unlikely to cause issues.

The BlueSea 250A/48VDC 4 x 5/16-18 stud m/n 2127 MSRP is $56USD. A quick on line search shows them available for as low as $32USD.

A DIY bus bar with an insulated base would be difficult to produce for that cost.

Yeah. That is a good price. But the one I see is 4.5 star 4 stud 200A at $12. That's why I'm trying to see if I can save my customer about $40 (off two) -- and to keep in reference for myself, in case I ever one to do my own -)).

For a Bus bar there is really no voltage limit at all, (except insulation quality on the mountings)

They all would be OK at under 50v as the insulation on them and they would all be rated to 50v, the amps is the MAIN issue you should be looking at as this is what they are sized for.

200amp is the same for 12 volt 24 36 and 48, ( thats unless there is some fancy switching included which would be very rare.)

Thank you. This is consistent with another user of the product. She said she is using it with 48V even though its rated for 12V 200A. She never responded when I asked how many amps/watts she was pushing through the bus.

The mounts are rated for 24V. The item itself is rated for 12V @ 200A. One black & one red for $20. Seems like a really good deal w/ 4.5 star and only complaint being not to over tighten the bolts .
