Eaton EDB3175L - 175 A, 240 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton EDB3175L—a rugged 175 A, 240 V, 3-pole molded case circuit breaker engineered to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Designed for real-world electrical environments, it helps keep residential, commercial, and light industrial systems safe, organized, and ready for service.

Why the EDB3175L stands out

• Compact molded case design optimizes panel space without sacrificing performance, letting you fit higher-capacity protection into tighter electrical enclosures.
• Thermal-magnetic trip unit provides stable, repeatable protection across varying loads and temperatures—balancing longer life with prompt response during faults.
• 3-pole configuration ensures coordinated protection for three-phase circuits, helping prevent imbalances and minimizing damage to equipment.
• 175 A, 240 V rating supports substantial branch circuits typical of commercial and light industrial loads while remaining suitable for large residential applications.
• OEM-compatible designed to pair with matching Eaton OEM load centers and panelboards for streamlined installation and reliable performance.

Practical applications and use cases

Ideal for panelboards and load centers in a variety of settings, the EDB3175L protects large branch circuits such as 3-phase motor feeds, HVAC equipment, and high-draw lighting or power distribution panels. It’s a solid choice when you need robust protection for critical infrastructure in spaces where panel real estate matters and dependable trip behavior is essential.

Protection that matters

The thermal element in the trip unit reacts to sustained overloads, while the magnetic mechanism engages instantly on high-energy faults. The result is coordinated, predictable disconnection that minimizes damage to conductors and connected equipment, reduces downtime, and supports safer maintenance windows.
