Eaton ED3225 - 225 A, 240 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton ED3225 — a 225 A, 240 V, 3-pole molded-case circuit breaker designed to guard panelboards and loadcenters against overcurrent and short-circuit events. Built to fit Eaton's ecosystem and many compatible OEM panels, it delivers dependable protection where you need it most.

• Compact, space-efficient design — the molded-case construction makes efficient use of panel space, helping you fit more protection in tight electrical enclosures.
• Thermal-magnetic trip unit — provides stable, repeatable protection across varying temperatures and loads, with fast magnetic response to short circuits.
• OEM panel compatibility — engineered to pair with matching Eaton OEM loadcenters and panelboards for a precise fit and reliable electrical performance.
• Versatile application — ideal for residential service panels, commercial distribution, and light industrial circuits requiring 3-pole 240 V protection.
• Reliable 3-pole protection — 225 A rating safeguards main feeders and branch circuits while maintaining coordinated protection with other devices in the system.
