Eaton CVH3225X3 - 225 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton CVH3225X3 is a 225 A, 240 V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built to endure the rigors of residential, commercial, and light industrial environments, this unit combines robust mechanical design with precise electrical protection.

Key advantages that matter in real-world panels

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays tight through temperature swings and equipment cycling, reducing the risk of loose connections and undesirable trips.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding accurately to both overloads and short circuits, helping to minimize nuisance trips while preserving safety.
• OEM-compatible designed to work with matching Eaton loadcenters and panelboards, simplifying installation, maintenance, and future system compatibility.
• High-current, three-pole design rated at 225 A and 240 V, suitable for balanced protection in three-phase power setups or configured in compatible panelboards for single-phase applications.
• Versatile for multiple sectors ideal for residential service upgrades, commercial panels, and light industrial applications where reliable branch-circuit protection is essential.
