What this molded case switch is
The ABB XT2LU3030AFF000XXX is a XT2L 125 TMF molded case switch — a non-automatic switch-disconnector in the XT2L frame, rated for the 125 A frame size. It is listed under the title XT2LU3030AFF000XXX and carries the description ABB XT2LU3030AFF000XXX XT2L 125 TMF molded case switch, current lifecycle stage. This is a molded case switch, meaning it provides manual switching and isolation of circuits under load, but without integral overcurrent protection — it is a switch-disconnector, not a circuit breaker. It belongs to the XT2L family, ABB's compact molded case platform for panel building and distribution.
Sourced through independent distribution channels, quoted to order against the BOM quantity.
Integration context for panel builders
As a molded case switch in the XT2L frame, it mounts in standard panel cutouts and connects via busbar or cable — the 125 A frame is sized for feeder and branch switching in distribution boards, motor control centres, and machine control panels. The TMF designation indicates a thermal-magnetic release mechanism, though as a switch (not a breaker) the release is for switching duty rather than protection coordination. The XT2L family is designed for DIN-rail or screw-mount integration, with finger-safe terminals and a compact footprint that saves panel space compared to older molded case platforms. No specific IP rating is listed, so standard indoor panel installation is assumed.
