5ST3043 is made by Siemens and is listed in our Miniature Circuit Breakers category. KKM Solutions is an independent distributor, not an authorized Siemens dealer: we source the exact Siemens part number 5ST3043, and the quote confirms condition and lead time before you order.

Parts we supply are new and genuine unless the quote expressly states otherwise. Where a part is surplus, new-old-stock, refurbished or open-box, the quote says so before you approve it.

Parts we supply are warranted against manufacturing defects for 1 year from the date of delivery; where the manufacturer's own warranty is longer, the manufacturer's warranty applies. The warranty covers repair, replacement, or credit of the defective part and does not cover normal wear items, misapplication, improper installation, or consequential damages. Contact us within 30 days of delivery before returning anything — all returns need a return authorization from the order desk.

No published lifecycle status is on file for 5ST3043. Siemens lists whether a catalog number is current, superseded or end-of-life on its own product page, and our order desk confirms the status with the manufacturer at quote time, before you commit. Send the part number through the quote form on this page.
