125 A, 22 kA — the protective envelope
The A2N125TL-2 is a 2-pole molded-case breaker rated 125 A continuous at 240 VAC, with a 22 kA interrupting capacity that clears a bolted fault at the panelboard without cascading upstream. The thermal-magnetic (TMF) trip element handles overloads on the thermal side and short-circuits on the magnetic side — the 125 A continuous rating means it holds a 125 A load indefinitely at 40 °C ambient, then opens on a sustained overcurrent per the inverse-time curve.
Sourcing — quoted to order
Lot quantities are verified per the BOM line; the breaker ships with line/load lugs as standard.
