MBA12 is a GE part. KKM Solutions sources GE components to the exact manufacturer specification and cross-checks every order against manufacturer part data before it ships.

KKM Solutions does not publish a manufacturer lifecycle status for MBA12 — check GE's own product page for whether it is current, superseded, or end-of-life. It does not change what we can do: we source current-production, superseded and long-obsolete parts the same way, and where a part is genuinely unavailable we identify a form-fit-function equivalent. Send the part number through the quote form on this page, or use our obsolete part lookup at https://kkmsolutions.com/tools/obsolete-part-lookup/.

Key specifications include Current rating: 800 A; Voltage rating: 277 V. The full specification table on this page lists every published attribute for this part.

In-stock items are dispatched the same business day for orders placed by 11 AM; sourced and quoted items ship per the quoted lead time. KKM Solutions ships worldwide — to your site, warehouse, or freight forwarder.
