Westinghouse | KDC3300 | Circuit Breaker | 300A | 3-Pole | 600V

Protect your three‑phase system with precision using the Westinghouse KDC3300 Circuit Breaker. Built for reliability in demanding environments, this 300A, 3‑pole breaker is designed for 600V applications and is ideal for maintenance, retrofit, and replacement projects where exact specifications matter. When your panel requires an exact Westinghouse reference, the KDC3300 is the clear, compatible choice.

• Amperage: 300 A
• Poles: 3‑Pole
• Voltage rating: 600 V

Why this matters for your electrical protection needs: a 3‑pole configuration ensures proper handling of three‑phase loads, delivering coordinated protection across all live conductors. The KDC3300 is purpose‑built to drop in where a like‑for‑like replacement is required, helping minimize downtime and compatibility risks in commercial and industrial panels.

• Ideal for: replacement in Westinghouse-compatible panels, retrofit projects upgrading feeders, and maintenance scenarios where a 300A, 3‑pole, 600V breaker is specified.
• Use case clarity: perfect for upgrading or maintaining three‑phase distribution where consistent trip characteristics and panel compatibility are essential.

Fit and compatibility: Always confirm fit and ratings before ordering. The part number KDC3300 serves as the most reliable reference for matching your panel configuration and system requirements. This reduces the guesswork often involved in sourcing replacements and helps ensure you receive the exact device your installation calls for.

Practical tips for installation and safety: review your panel’s model and rating, verify that a 3‑pole 600V device aligns with your distribution plan, and follow standard electrical safety protocols during replacement. If you’re coordinating an upgrade, plan for any associated wiring changes or breaker bar adjustments that accompany a like‑for‑like swap to maintain proper clearance and labeling.
