Square D | HLA360456 | Circuit Breaker | 45A | 3-Pole | 600V

The Square D HLA360456 circuit breaker delivers dependable, three‑phase protection designed for demanding electrical distributions. With a 45A rating, 3-pole configuration, and a 600V maximum, this unit is tailored for retrofit, maintenance, and replacement in compatible Square D panels.

• Amperage: 45A
• Poles: 3‑Pole
• Voltage: 600V
• Part number: HLA360456
• Compatibility note: The part number is the best reference for compatibility. Confirm fit and ratings before ordering.

This model excels in scenarios where reliable three‑phase protection is essential—industrial control panels, motor drives, and power distribution boards that operate at up to 600V. Ideal for maintenance, retrofit, and replacement projects, it helps preserve system safety and continuity by matching existing specifications exactly.

Why this breaker stands out

• Exact match for Square D panel configurations, reducing the risk of misfit components during upgrades
• 3‑pole design provides balanced protection across all three phases, which is crucial for motors and 3‑phase equipment
• Clear, unambiguous compatibility through the official part number (HLA360456) for streamlined procurement

Ideal use cases

• Retrofit of aging or incompatible panels to restore reliable 3‑phase protection
• Replacement in manufacturing lines, processing equipment, and HVAC distribution networks
• New installations where a 3‑pole, 45A breaker up to 600V is required

Installation and safety considerations

Always disconnect power and follow your panel’s installation guidelines when inserting or replacing a breaker. Because fit and ratings are critical, verify that the HLA360456 part aligns with your panel model and system voltage before proceeding. If in doubt, reference the panel’s documentation and confirm that the breaker's amperage, poles, and voltage match the specific circuit requirements.
