Eaton CHH3225H4X - 225 A, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton CHH3225H4X is a 225A, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built for reliability, it combines rugged mounting with precise protection so you can trust it to stay put and perform when it matters most.

Key advantages that set this unit apart:

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection—reducing connection looseness and ensuring consistent electrical performance in environments where equipment vibrations are common.
• Thermal-magnetic trip unit providing stable, repeatable protection across varying temperatures and load conditions. Overloads are handled with a controlled thermal response, while short circuits trigger an instantaneous magnetic trip to protect wiring and downstream devices.
• 3-pole design ideal for multi-phase circuits typical in residential, commercial, and light industrial panel configurations.
• OEM compatibility works with matching Eaton OEM load centers and panelboards, simplifying replacements, upgrades, and service continuity.
• Targeted protection specifically intended for branch circuit overcurrent and short-circuit protection, helping safeguard wiring, devices, and infrastructure without unnecessary nuisance tripping.
