Lifecycle & Sourcing
The XT4NU2200AJJ000XXX: The lifecycle stage is marked as current, meaning ABB still manufactures and supports this order code as a standard catalog item. No EOL notice or last-time-buy window applies. For a BOM freeze or a line-down replacement, this part is available through independent distribution channels — sourced and quoted to order against an RFQ, with availability and current pricing confirmed at quote time. If you are planning a multi-year build, this is a safe part to freeze into the BOM without worrying about a sudden phase-out.
Integration & Compliance
Mounts on standard DIN rail or panel plate. The 2-pole footprint leaves room for auxiliary contact blocks or shunt trips on the side. Compliance documentation (RoHS, REACH, UL, IEC) is available from ABB's product support portal for this order code — the part carries the usual ABB declarations for industrial control gear. No special wiring beyond standard lug torque values; the TMF thermal-magnetic trip unit provides both overload and short-circuit protection in one package.
