Westinghouse | HLA3300 | Circuit Breaker | 300A | 3-Pole | 600V

Westinghouse HLA3300 Circuit Breaker is a robust three-pole protection device rated for 300 amperes and 600 volts, designed for reliable performance in electrical distribution panels. Built for maintenance, retrofit, and replacement projects, it helps keep systems protected while simplifying upgrades.

The HLA3300 fits into three-pole, 600V circuits, delivering dependable interruption capabilities when overcurrent occurs. Its spec alignment ensures you can match existing panel and bus configurations with confidence, reducing downtime and compatibility concerns.

Why this Westinghouse HLA3300 stands out

• Three-pole protection for balanced, three-phase systems: Ideal for 3-phase power distribution where a fault can affect multiple legs.
• 300A current rating: Handles high-load circuits common in commercial or industrial panels without frequent nuisance trips, while still providing clear overcurrent protection.
• 600V maximum voltage: Suitable for higher voltage distribution environments, ensuring compatibility with modern electrical installations.
• Clear compatibility reference: Part number HLA3300 is the best reference; always verify fit and ratings before ordering to ensure proper panelboard or bus compatibility.
• Maintenance, retrofit, and replacement-ready: A practical choice when updating an existing installation or stocking spare parts for service calls.

How to use it effectively

Before purchasing, confirm your panel’s model and the bus arrangement to ensure a seamless swap. When installing, follow standard electrical safety practices and torque requirements specified by your panel manufacturer. If you’re replacing an existing unit, use the HLA3300 as the direct compatibility reference to minimize downtime.

Ideal scenarios and use cases

• Upgrading an aging electrical distribution panel where a 3-pole, 600V, 300A breaker is required for current load and future expansion.
• Retrofits in commercial spaces with three-phase equipment, motors, or HVAC systems that demand robust overcurrent protection.
• Spare parts planning for service engineers who manage multi-site facilities and need ready-to-deploy replacements.

Choose the Westinghouse HLA3300 when you need trustworthy, match-ready circuit protection that aligns with your existing infrastructure. It’s a practical, no-surprises solution for critical power sections that require dependable interruption performance and straightforward cross-reference using the established part number.
