Schneider Electric Q222125ACH Circuit Breaker

Schneider Electric's Square D Q2 series Q222125ACH is a 2-pole molded‑case circuit breaker rated for 125 A at 240 VAC, designed for I‑Line plug‑in panels in commercial and light‑industrial electrical systems. It provides thermal‑magnetic protection with a 10 kA short‑circuit interrupt rating at 240 V, delivering reliable interruption during faults while minimizing nuisance trips under overloads. The unit's two‑pole construction ensures simultaneous isolation of both live conductors, making it suitable for 240 V circuits within compatible Square D panels and buses. As part of the Q2 family, this breaker uses a non‑interchangeable trip mechanism and supports long‑time and instantaneous trip functions, giving precise protection for feeders and branch circuits. This model is UL‑listed and commonly stocked by suppliers as a direct replacement or upgrade in legacy installations that require 125 A protection, and it is widely identified by its Q2 designation and the Q222125‑ACH suffix. Typical applications include protection of feeders to industrial equipment, HVAC equipment, or other 240 V loads in facilities that use Square D Q2 breakers and I‑Line bus systems.
