Eaton FDC3175 - 175 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton FDC3175 is a 3-pole bolt-on molded case circuit breaker rated for 175 A at 600 V, crafted to deliver reliable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built for consistent performance in demanding environments, this breaker helps keep electrical systems safe and running smoothly.

Key advantages you’ll notice in real-world installations:

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to bus bars, reducing the risk of loose terminations in panels subjected to mechanical stress or vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining thermal and magnetic sensing to handle both sustained overloads and instantaneous short-circuit events.
• OEM-compatible design is engineered to work with matching Eaton load centers and panelboards, ensuring proper fit, traceability, and coordinate protection across the system.
• Versatile application suited for residential, commercial, and light industrial environments where dependable circuit isolation and quick fault interruption are critical.

Why this makes a difference

Choosing the Eaton FDC3175 means prioritizing reliability and ease of installation in one package. The bolt-on design minimizes connection issues in busy electrical environments, while the thermal-magnetic trip unit reduces nuisance trips and provides fast clearance during faults. When paired with compatible OEM panels, it helps maintain protective coordination across the electrical distribution system, enhancing safety and reducing downtime.

Practical guidance for use

• Pair with the corresponding Eaton panelboard or load center to ensure seamless fit and electrical coordination.
• Plan for 175 A load-carrying capability on feeder or branch circuits, with consideration for upstream protective devices and conductor sizing.
• Follow standard electrical safety practices during installation; bolt-on mounting should be torqued to the panel’s specified requirements to maintain a solid connection.

For projects requiring a dependable, high-capacity 3-pole solution with a secure mounting method and proven protection characteristics, the Eaton FDC3175 stands out as a practical, purpose-built choice. AmpState stocks this model to support commercial, industrial, and residential panel needs with a component you can trust to perform when it matters most.
