Westinghouse | HLCG3400F | Circuit Breaker | 400A | 3-Pole | 600V

Meet the Westinghouse HLCG3400F circuit breaker — a reliable 400A, 3-pole protection solution designed for 600V systems. Built for maintenance, retrofit, and replacement applications, this unit ensures you can restore or upgrade electrical protection with specifications that match your existing hardware.

Key specifications

• Amperage: 400A
• Poles: 3-Pole
• Voltage rating: 600V
• Part number: HLCG3400F
• Important: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Why this matters in your system

In three-phase, 600-volt electrical networks, a 3-pole breaker like the HLCG3400F provides synchronized protection across all phases. This reduces the risk of phase imbalances and gear damage during faults, helping to protect downstream equipment and simplify service procedures. By using the exact part number, you minimize uncertainty about compatibility with your panel or enclosure, ensuring a smoother retrofit or replacement process.

Ideal use cases

• Panel maintenance where a direct, spec-matched replacement is required.
• Retrofits upgrading to a 400A, 3-pole protection scheme on 600V distribution systems.
• Replacement for worn or obsolete breakers in industrial or commercial electrical equipment that operates on 3-phase power.

Practical considerations and tips

• Always verify that your panel or switchgear supports a 400A, 3-pole, 600V device and that the HLCG3400F matches the panel’s compatibility requirements.
• Keep documentation on file for your specific installation — the part number is the most reliable reference for future maintenance and reorder needs.
• When installing, ensure proper torque and secure termination for both line and load connections, and follow all safety procedures for de-energizing and servicing high-current equipment.
