The ABB A1N100TW is a Thermal Magnetic circuit breaker from the A1N 100 TMF 100-1000 series, identified by the order code A1N100TW.
Sourcing and replacement path
Because the A1N100TW is eol_hot, sourcing relies on independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No official successor or pin-compatible alternative is recorded in the manufacturer's documentation; any replacement requires a parametric cross-check against the original BOM.
