General Electric | TJD422400WL | Circuit Breaker | 400A | 2-Pole | 240V

Meet the General Electric TJD422400WL circuit breaker — a purpose-built, high-current protection device designed for demanding 240V applications. This 400A, 2-pole breaker is the reliable choice for maintenance, retrofit, and replacement projects where exact specifications matter, ensuring your electrical system stays safe and compliant under heavy loads.

Key specifications

• Amperage: 400A
• Poles: 2-Pole
• Voltage: 240V
• Part number: TJD422400WL
• Manufacturer: General Electric (GE)
• Reference note: Confirm fit and ratings before ordering; the part number is the best reference for compatibility.

Why this GE 400A 2-pole breaker stands out

• Precise compatibility for GE panels — designed to work within the GE ecosystem, particularly when the exact part number is required for service or upgrades.
• Robust protection for large feeders — 400A rating is ideal for heavy-duty feeders and high-load circuits, helping prevent overheating and electrical faults.
• Dual-pole safety — the two-pole design ensures both hot legs of a 240V circuit trip together, providing coordinated disconnection for safer, more reliable shutdowns.
• Retrofit-ready — a practical solution for panel upgrades, replacements, or retrofits where the system calls for a matching GE 400A, 2-pole, 240V device.

Ideal use cases

• Upgrading or replacing high-current feeders in GE-compatible main or subpanels.
• Maintenance scenarios where a precise part number (TJD422400WL) is required to restore original protection specs.
• Retrofit projects in commercial or industrial environments that demand solid 240V protection for large equipment or multiple circuits.

Installation and safety notes

Professional electrical installation is recommended. Always ensure the power is completely shut off and follow local codes and the panel manufacturer’s instructions. Verify that the panel supports the GE TJD family and that the 400A, 2-pole, 240V ratings align with the system’s requirements before integrating this breaker.

Tips for optimal performance

• Keep the part number (TJD422400WL) handy as the primary reference for compatibility checks during service or procurement.
• Document the replacement in your maintenance logs to simplify future repairs or upgrades.
• Store and handle breakers in a clean, dry environment to preserve connection integrity over time.
