Eaton FD4225L - 225 A, 600 V, 4-Pole Bolt-On Circuit Breaker | AmpState

The Eaton FD4225L is a 225 A, 600 V, 4-pole bolt-on molded case circuit breaker engineered to protect electrical systems with precision and lasting reliability. Built for dependable branch circuit overcurrent and short-circuit protection, it’s a proven choice for panelboards and loadcenters where rugged performance matters.

Why the FD4225L stands out

• Secure bolt-on mounting delivers a rigid, vibration-resistant bus connection. This reduces micro-movements that can degrade contact performance in demanding environments, ensuring consistent protection over time.
• Thermal-magnetic trip unit provides stable, repeatable protection by responding to both sustained overloads and instantaneous faults. This helps prevent nuisance trips while still offering fast isolation when needed.
• 4-pole design is ideal for 3-phase systems with a shared neutral, delivering complete circuit protection and isolation across all poles.
• OEM-compatible design means seamless pairing with matching Eaton OEM load centers and panelboards, helping to maintain system integrity and streamlined installation.
• Broad applications suitable for residential, commercial, and light industrial installations where robust branch-circuit protection is a must.

Practical use cases

Install the Eaton FD4225L in new panel projects or when upgrading existing distributions in homes, small offices, retail spaces, or light industrial facilities. It excels in environments subject to vibration, frequent cycling, or where a solid, low-resistance bus connection is critical for reliable fault isolation. The 225 A rating at 600 V makes it well-suited for feeders and subfeed configurations that demand strong overload protection and quick short-circuit clearing.

What problems it solves

• Prevents damage from electrical faults by delivering precise overcurrent protection across all four poles.
• Minimizes unwanted trips on ordinary load changes thanks to a calibrated thermal-magnetic mechanism.
• Eliminates compatibility concerns by aligning with Eaton’s own load centers and panelboards, supporting a cohesive, easy-to-service electrical distribution system.
