Square D HLA36060AA 36060A 3-Pole 600 V Circuit Breaker

Engineered for robust three‑phase protection, the Square D HLA36060AA 3‑Pole 600 V Circuit Breaker is built to safeguard industrial electrical systems from overcurrent events. This part, HLA36060AA, delivers dependable interruption across all three phases, helping protect motors, feeders, and panelboards in demanding environments.

Key specs

• Current rating: 36060 A
• Poles: 3
• Voltage rating: 600 V
• Part number: HLA36060AA
• Brand: Square D

Use cases and benefits

Three‑pole protection is essential for balanced three‑phase power. In manufacturing facilities, this breaker guards motor drives, conveyors, and HVAC compressors. In data centers and critical environments, it protects power distribution feeders from short circuits and overloads, helping minimize downtime and equipment wear. The 600 V rating makes it suitable for industrial and commercial main panels, switchboards, and control panels where higher voltage operation is required.

What sets this apart

Unlike single‑ or two‑pole devices, this 3‑Pole breaker ensures synchronized disconnection on all three phases, preventing phase imbalance and potential motor damage. The Square D legacy behind the HLA series adds confidence in performance, replacement availability, and service compatibility across standard Square D panels.

Installation and compatibility tips

• Verify that your panel or enclosure accepts HLA‑series breakers and that the mounting and bus connection geometry match the HLA36060AA.
• Confirm that a 600 V classification matches your system and local electrical code requirements.
• Ensure conductor sizes and protection settings align with the current rating (as specified: 36060 A) and that conductors are terminated with proper torque per manufacturer guidelines.
• Keep spare breakers on hand for future panel upgrades or expansion to maintain consistent protection across circuits.

Invest in the Square D HLA36060AA 3‑Pole 600 V Circuit Breaker to deliver reliable overcurrent protection for three‑phase systems, with the assurance of Square D's global support and a clear path to service or replacement in the future.
