XKL631400 | Circuit Breaker | 400A | 3-Pole | 600V

Meet the XKL631400 circuit breaker — a purpose-built solution for industrial power distribution. With 400A capacity across three poles at 600V, this unit is designed for robust protection in demanding environments where reliability matters.

Designed for maintenance, retrofit, and replacement projects where exact specifications matter, the XKL631400 ensures you're matching the right device for your panel and system. Use this part number as your primary compatibility reference to minimize downtime and ensure seamless integration.

Key specifications

• Amperage: 400A
• Poles: 3-Pole
• Voltage: 600V

Why this matters in real-world use

In a three-phase setup, a 3-pole breaker protects all conductors simultaneously, preventing phase imbalance and providing coordinated shutdown in fault conditions. The 600V rating expands its suitability to a wide range of industrial feeders and equipment while maintaining safety margins. This breaker is ideal for service panels, motor control centers, and retrofit projects where a like-for-like replacement is required to maintain electrical protection schemes.

Use cases and ideal applications

• Maintenance: replace worn or failed breakers in aging control panels with a trusted, compatible unit.
• Retrofit: upgrade legacy systems to a current design that matches existing ratings and 3-phase protection.
• Replacement: quick reference by part number for fast ordering and reduced downtime.
• New installations: used where a 400A, 3-pole, 600V breaker is required for primary feeders or main disconnects.

Important compatibility notes

Always verify fit and ratings before ordering. The part number XKL631400 is the best reference for compatibility with your equipment. Cross-reference against the panel label and the system’s voltage and current requirements to ensure a seamless fit.
