XKL3300 | Circuit Breaker | 300A | 3-Pole | 600V

The XKL3300 is a purpose-built industrial circuit breaker designed for maintenance, retrofit, and replacement projects where exact specifications matter. With a 300A rating, a 3-pole design for true three-phase protection, and a 600V capacity, this breaker delivers dependable interruption and protective shutdown for demanding electrical systems.

Why the XKL3300 stands out

• Exact compatibility with your gear — rely on the XKL3300 as the primary reference for fit and ratings. Confirm compatibility before ordering to ensure a seamless replacement in your panel or distribution setup.
• Three-pole protection — engineered for balanced coverage across all three phases, reducing the risk of uneven loading and phase-related faults in industrial environments.
• Robust 300A current capacity — handles substantial load demands common in manufacturing, processing lines, and heavy equipment feeders without compromising safety.
• 600V voltage rating — suitable for typical industrial distribution networks, giving you reliable performance in demanding plant environments.
• Maintenance, retrofit, and replacement ready — this model is ideal for updating legacy panels, upgrading protection schemes, or stocking a ready-to-go replacement part for critical lines, helping minimize downtime.

Ideal applications and scenarios

• Upgrading or retrofitting three-phase power systems in manufacturing facilities, processing plants, or industrial machinery rooms
• Replacement for aging breakers in panels that require a precise 300A, 3-pole, 600V specification
• Maintenance projects where matching the original part number (XKL3300) ensures compatibility with existing bus bars and mounting configurations

Important compatibility notes

• Before ordering, verify fit and ratings against your panel documentation. The part number XKL3300 is the best reference for compatibility.
• Confirm that your system’s bus bar size and enclosure are rated for 600V and support a 300A, 3-pole device.
• When in doubt, consult a licensed electrician or your facility’s electrical engineer to validate installation requirements and safety considerations.
