Eaton CA2225 - 225 A, 240 V, 2-Pole Circuit Breaker | AmpState

The Eaton CA2225 is a 225A, 240V, 2-pole molded case circuit breaker designed to deliver dependable branch-circuit protection in panelboards and loadcenters. Its compact form reduces panel clutter while the thermal-magnetic trip unit delivers stable, repeatable protection for both overload conditions and short circuits. Built to integrate with matching OEM panelboards, this breaker is a smart choice for both upgrades and new installations that demand robust 240V protection.

• Compact molded-case design prioritizes space efficiency, making it easier to fit large feeders and multiple circuits in tight panel enclosures—ideal for crowded residential panels, small commercial spaces, and light industrial installations.
• Thermal-magnetic trip unit provides reliable protection by combining a thermal element for steady overload sensing with magnetic action for fast, instantaneous response to short circuits. The result is predictable trip behavior and improved protection coordination with nearby devices.
• 2-pole, 240V operation protects both conductors of a 240V circuit, making it well suited for motors, HVAC equipment, large appliances, and feeder circuits that require simultaneous interruption on both legs.
• OEM loadcenter compatibility designed to work with matching Eaton loadcenters and panelboards, ensuring correct fit, mechanical alignment, and seamless replacement in existing installations.
• Ideal for a range of sectors from residential upgrades and commercial offices to light-industrial applications where reliable 225A protection is needed without sacrificing panel space.
