Frequently Asked Questions
How do I get pricing for AC1256?
KKM Solutions is a quote-based industrial supplier, so prices are not listed online. Send the quote form on this page with your quantity, or email [email protected], and our order desk will reply with pricing and availability within 1 business day.
Who manufactures the AC1256?
AC1256 is a IFM part. KKM Solutions sources IFM components to the exact manufacturer specification and cross-checks every order against manufacturer part data before it ships.
What is the lifecycle status of AC1256?
We do not hold a published lifecycle status for AC1256. IFM's publishes whether a catalog number is current, superseded or end-of-life on its own product page, and our order desk confirms the current status with the manufacturer at quote time — you are told if the part is superseded or discontinued before you commit. Either way we source current-production, superseded and long-obsolete parts the same way; where a part is genuinely unavailable we identify a form-fit-function equivalent.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/.
What are the key specifications of AC1256?
Key specifications include Ambient temperature: -25...70; AS-i certificate: 98701; Back feeding protection: 35; Derating: 0 (60...70 °C). The full specification table on this page lists every published attribute for this part.
How quickly can AC1256 ship?
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.
