A3T40 Mersen A3T 40A 300VAC/160VDC, fast acting/class T

A3T40 is listed at CA$53.28 (CAD) and can be ordered directly from this page with Add to Cart. That figure is a reference price and can change: your card is authorized at checkout and charged only once our order desk confirms the part, stock, and final price, and we email you first if anything has moved. Larger quantities or custom terms — email orderdesk@kkmsolutions.com for a volume quote.

A3T40 is made by Mersen and is listed in our Circuit Protection category. KKM Solutions is an independent distributor, not an authorized Mersen dealer: we source the exact Mersen part number A3T40, 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 new-old-stock, from excess inventory, 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 A3T40. Mersen lists whether a catalog number is current, superseded or end-of-life on its own product page, and our order desk confirms the status with the manufacturer at quote time, before you commit.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.

Lead time for A3T40 is quoted per order and confirmed on your quote, which our order desk sends within 1 business day. For a line-down emergency, call the 24/7 order desk at (825) 454-5367.
