Schneider Electric KA225 Molded Case Circuit Breaker

Schneider Electric's Square D KA225 molded-case circuit breaker is a 225 A, two-pole device built on the KA frame for 600 V AC service. This legacy KA-frame MCCB is designed for industrial enclosures, panelboards, and switchboards where robust overcurrent protection is required in commercial and light-industrial installations. The KA family—including KA, KC, KH, and KI molded-case breakers—supports applications up to 600 V and is used across a range of industrial control and distribution gear from Schneider Electric. The 2-pole configuration provides simultaneous interruption of two conductors, making it well suited for protecting feeders and branch circuits in systems that standardize on KA-frame breakers, and it integrates with mounting arrangements typical of legacy equipment.
