The 'A1A 100' frame means the breaker sits in the ABB A1A 100 platform — a compact MCCB line for panelboard and distribution boards up to 100 A frame. The thermal-magnetic trip gives you inverse-time overload protection (thermal) plus instantaneous short-circuit pickup (magnetic), both fixed at the 50 A mark. ## Lifecycle reality — eol_hot means order while you can If you need a drop-in replacement, you'll need to check the A1A 100 family's current catalogue for a comparable fixed-trip thermal-magnetic MCCB with the same frame and 50 A rating. The page does not carry a direct pin-compatible alternative. ## Sourcing this MCCB — quoted to order The A1A050TW-1 is sourced through independent distribution channels. For a line-down spare or a BOM freeze, send the quantity and target lead time; the desk will quote against the available channel inventory.","metaTitle":"ABB A1A050TW-1 A1A 100 TMF 50, Thermal Magnetic MCCB, 50 A","metaDescription":"ABB A1A050TW-1 A1A 100 TMF 50 thermal magnetic MCCB, 50 A fixed trip, eol_hot lifecycle.
