Eaton CC3175 - 175 A, 240 V, 3-Pole Circuit Breaker | AmpState

The Eaton CC3175 is a compact, reliable solution for protecting large branch circuits in panelboards and load centers. At 175 A and 240 V, this 3-pole molded case circuit breaker delivers precise, dependable overcurrent and short-circuit protection where it counts, built to integrate with matching OEM loadcenters for a seamless upgrade or expansion.

• Compact molded-case design optimizes panel space, making it easier to fit in crowded electrical enclosures without sacrificing performance.
• Thermal-magnetic trip unit provides stable, repeatable protection, responding quickly to overloads and faults to help protect wiring and connected equipment from damage.
• 3-pole configuration is ideal for three-phase circuits, enabling robust protection in commercial and light industrial installations operating at 240 V.
• 175 A amperage rating supports sizable feeders and branch circuits while maintaining coordination with upstream protection devices.
• OEM-compatibility designed to work with matching Eaton loadcenters and panelboards for straightforward replacement, maintenance, or system expansion.
• Versatile application suitable for residential, commercial, and light industrial environments, including service upgrades, distribution boards, and new panel installations.

Why it matters: In any electrical distribution system, the right breaker combination matters for both safety and uptime. The CC3175’s molded-case construction reduces panel congestion and improves cooling, while the thermal-magnetic trip curve delivers reliable protection across a range of fault conditions. This means fewer unexpected trips, clearer fault isolation, and a safer, more resilient electrical installation.

Use cases and practical scenarios

• Upgrading an existing panel to support additional 3-phase equipment in a small commercial space.
• Installing a new load center or expanding a distribution board where a 175 A, 240 V 3-pole protection device is required.
• Replacing a failed breaker with a compatible Eaton unit to maintain consistent protection characteristics and panel compatibility.
• Protecting large feeders and main distribution circuits in light industrial settings where reliability and compact space utilization are priorities.

How to get the most from the CC3175: Ensure your enclosure is compatible with Eaton OEM loadcenters, verify that the circuit requires a 3-pole 175 A device at 240 V, and follow standard torque and connection practices for molded-case breakers. Pair this breaker with properly rated conductors and upstream protection to achieve optimal coordination and safety across the system.
