A1N 100 TMF 15-400 frame — what the type string tells you
The ABB A1N015TW-2 is a thermal magnetic moulded-case circuit breaker from the A1N 100 series, with a TMF 15-400 trip unit. The '15-400' in the type string indicates the adjustable thermal-magnetic trip range — the breaker is set for a 15 A continuous rating within a frame rated up to 400 A. Thermal magnetic means it uses a bimetal strip for overload protection (time-delayed, inverse-time curve) and a solenoid for short-circuit instantaneous trip. This is the standard protection for feeder and branch circuits in industrial distribution panels, not for motor overloads where a separate overload relay is required.
Lifecycle status — eol_hot, sourcing reality
For a BOM line that requires this exact order code, the supply path is through independent distribution — quantities are lot-specific and confirmed at RFQ. There is no pin-compatible or form-fit-function drop-in replacement from ABB's current catalogue; a board or panel re-design would be needed for a functional alternative.
