HLA3450 | Circuit Breaker | 450A | 3-Pole | 600V

The HLA3450 Industrial Circuit Breaker is a purpose-built, three-pole protective device designed to safeguard three-phase electrical systems up to 600V. With a robust 450A rating, this breaker provides reliable protection for heavy equipment, manufacturing lines, and industrial control panels. Engineered for maintenance, retrofit, and replacement projects, it fits scenarios where exact specs and compatibility matter most.

Key specifications

• Amperage: 450A
• Poles: 3-Pole
• Voltage: 600V
• Type: Industrial circuit breaker

What sets HLA3450 apart

• Exact three-phase protection: The 3-Pole design ensures coordinated interruption across all phases, improving overall system safety and reducing the risk of unbalanced loads.
• Ready for retrofit and replacement: Ideal for upgrading existing panels or swapping in damaged units without changing the electrical architecture.
• Part-number precision for compatibility: Use HLA3450 as the primary reference to verify fit and ratings before ordering.
• Durable industrial build: Designed to withstand demanding environments and provide steady protection when it matters most.

Use cases

Some common scenarios include retrofitting aging three-phase panels, performing routine maintenance on production lines, and replacing failed breakers in upgrades where staying with a 450A/600V rating simplifies procurement and testing.

Before you buy

Always confirm fit and ratings prior to purchase. The part number HLA3450 is your most reliable reference for compatibility with your panel and upstream equipment. If your documentation lists the same specs, you’re likely choosing a like-for-like replacement that speeds re-commissioning and reduces downtime.
