Westinghouse | NC31200 | Circuit Breaker | 3-Pole | 480V | Bolt-On

Meet the Westinghouse NC31200 3-Pole, 480V bolt-on circuit breaker — a purpose-built protection device designed for reliable service in industrial electrical systems. Built to support maintenance, retrofit, and replacement projects, this model helps you preserve panel continuity while upgrading or restoring circuit protection with a component you can trust.

Key details

• Poles: 3-Pole
• Voltage rating: 480V
• Mounting: Bolt-On for secure, straightforward installation
• Part reference: NC31200 — use this number to confirm compatibility with your existing panel or enclosure

Why this Westinghouse breaker stands out

Unlike generic substitutes, the NC31200 is purpose-built to align with specific Westinghouse and compatible panels. Its bolt-on design streamlines retrofit projects, reducing downtime and simplifying sourcing because the part number directly corresponds to the required fit and ratings. This is a practical choice when you’re replacing aged or non-functioning breakers in a system that demands dependable 480V protection across three distinct poles.

Ideal use cases

• Maintenance-only replacements for aging 3-pole circuits in industrial facilities
• Retrofits to restore protection in panels that previously used compatible Westinghouse components
• Repairs where a precise 3-pole, 480V bolt-on solution is required to maintain system integrity

Compatibility and ordering guidance

For best results, verify fit and ratings before ordering. The part number NC31200 is the most reliable reference for compatibility with your panel and downstream equipment. When in doubt, cross-check the enclosure type, mounting footprint, and interrupting capacity against your existing protection scheme to ensure seamless operation after installation.

What you gain with a proper installation

• Consistent protection across all three poles, maintaining synchronized shut-off and reset behavior
• Predictable electrical performance within your 480V system, supporting reliable downstream operation
• Reduced maintenance interruptions through a straightforward bolt-on replacement path

Practical tips for success

• Before purchasing, map the existing breaker footprint and mounting hardware to confirm bolt-on compatibility
• Keep a reference to the NC31200 part number for future replacements or panel documentation
• Schedule installation during low-demand periods to minimize equipment downtime
