Quote a UL 508A control panel. Any brand.

Send your parts list. We check every part against the catalog, then quote the build.

Scoping the parts list is the slowest step in quoting a panel.

Every line has to be looked up in its own catalog, its ratings checked, and an alternate found for anything that may run long or is no longer sold.

Paste a part number and see what the catalog says about it.

Each one shows its description, its ratings and the catalog page it's printed on.

Free, with no contracts and no obligation.

Try one:

Your list carries over to a short form, so we know where to send the results.

Every panel quote starts with the free Parts Check.

Free. Nothing to commit to.

The full Parts Check

Reading the whole list together catches what no single line shows.

These come back as questions before the quote is final. Your team decides.

Every flag comes back with its reason, and an alternate where one fits.

Nearest available, differs on interrupting rating (higher). No exact match was found; this one needs your approval.

Matched (yours → alternate): Kind of product: circuit breaker · Poles: 3 · Trip curve / trip unit: thermal-magnetic · Trip rating: 100 A · Interrupting rating: 35 kA @480 V → 85 kA @240 V / 35 kA @480 V / 35 kA @480Y/277 V / 18 kA @600 V / 18 kA @600Y/347 V (covers yours) · Fixed vs adjustable trip: fixed trip

Order with it: Lug / terminal kit — order the lug / terminal kit, or the build is short a part

Confirm on the catalog data:

  • interrupting rating at your voltage
  • combination / series ratings
  • frame size and panel space — fit not compared

Each also covers your part on every rating compared; the further down the list, the further above your ratings it sits. Siemens 3VA5210-5ED31-0AA0 is tied with 3VA5210-5EC31-0AA0 on every rating compared. They differ in details we did not compare (options, versions or ratings not on file), so check the one you prefer before approving it instead.
