Eaton HFD3225 - 225 A, 3 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton HFD3225 is a 225 A, 3‑pole bolt‑on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short‑circuit protection in panelboards and loadcenters. Built for durability, its bolt‑on mounting provides a rigid, vibration‑resistant bus connection, helping prevent loose connections that can lead to nuisance trips.

Key benefits that matter in real world use

• Secure bolt‑on mounting: Creates a solid, vibration‑resistant connection to the bus, enhancing long‑term reliability in environments with movement or vibration.
• Thermal‑magnetic trip unit: Combines precise thermal protection with instantaneous magnetic response for stable, repeatable protection as loads change or surge events occur.
• OEM‑grade compatibility: Engineered to work with matching Eaton OEM loadcenters and panelboards, ensuring coordinated protection and straightforward installation.
• High current capacity: 225 A rating makes it suitable for main or feeder protection in larger branch circuits across residential, commercial, and light industrial settings.

Where and how you’ll use it

Ideal for upgrading or outfitting panel systems where robust, reliable protection is essential. Use cases include:

• Residential subpanels and multi‑unit buildings that require durable, consistent circuit protection
• Commercial lighting and equipment feeders that experience moderate to high inrush currents
• Light industrial distribution panels where vibration resistance and secure electrical connections matter
