• Current rating: 400 A
• Poles: 3
• Voltage rating: 600 V
• Part number: LGE340033W
• Configuration: 3‑pole, ideal for three‑phase power distribution

Who benefits from this GE circuit breaker? facilities with high‑demand three‑phase loads such as large motors, compressors, HVAC systems, and substantial lighting or processing circuits. If your panel or distribution gear operates on three phases and requires reliable interruption at up to 600 volts, this unit is engineered to handle the load with precision and durability.

Why this 400A 3‑pole breaker stands out

• Robust fault protection: With a 400 A capacity, it’s built to handle heavy feeders while providing dependable disconnection when faults occur.
• Three‑phase coordination: The 3‑pole design ensures simultaneous isolation of all three live conductors, reducing risk and improving system safety compared to single‑pole solutions.
• Industrial‑grade voltage handling: The 600 V rating makes it well suited for commercial and industrial environments where higher voltage distributions are standard.
• Trusted GE reliability: Leveraging GE engineering, this breaker aligns with established standards for long‑term performance in mission‑critical applications.

Practical use cases and scenarios

• Protecting large three‑phase motors in manufacturing lines, ensuring quick fault clearance to minimize downtime.
• Feeding heavy electrical equipment via main distributions in commercial facilities, helping to prevent cascading outages.
• Replacing worn or failed breakers in older GE systems with a compatible, high‑current alternative that maintains system protection.

Installation and compatibility notes

• Designed for use in compatible GE panels and distribution setups that require a 3‑pole, 400 A, 600 V protection device.
• Ensure proper alignment with bus bars and follow local electrical codes during installation. Have a licensed electrician perform or supervise the work.
• Verify system requirements match the current, voltage, and configuration before replacement or retrofit to maintain safe, effective operation.

For engineers and technicians who demand reliable, high‑current protection in three‑phase systems, the GE LGE340033W 400A 3‑Pole 600 V Circuit Breaker offers a precise balance of capacity, safety, and durability.
