This is the same platform used across the A2A series for panelboard and switchboard feeder disconnects. The TMF designation means the trip unit combines a thermal element for overload protection with a magnetic element for short-circuit response — the 250-2500 range covers the adjustable magnetic pickup from 250 A up to 2500 A, giving selectivity headroom downstream. ## EOL — hot surplus sourcing For a line-down or MRO spare, this is a broker-sourced part: quantities are lot-specific and confirmed at RFQ. The TMF trip block is field-replaceable, so a used unit with a good trip block can still serve as a drop-in spare for an existing A2A 250 frame. ## Sourcing and compliance Sourced through independent surplus and liquidation channels — not from ABB factory stock.","metaTitle":"ABB A2A250TW A2A 250 TMF 250-2500, 250 A, 3-pole","metaDescription":"ABB A2A250TW A2A 250 TMF 250-2500 molded case switch, rated 250 A, 3-pole.
