Square D HGA36015AA 36015A 3-Pole 600 V Circuit Breaker

Protect essential three‑phase power with precision using the Square D HGA36015AA 3‑Pole 600 V Circuit Breaker. Built for reliability in demanding environments, this device delivers fast, predictable tripping to shield motors, drives, and other 3‑phase loads from overloads and faults.

• Part Number: HGA36015AA
• Poles: 3
• Voltage rating: 600 V
• Current rating: 36015 A

Designed for industrial panels and distribution gear, the Square D HGA36015AA integrates seamlessly with 3‑phase electrical systems. It’s an ideal choice for facilities with three‑phase motors, HVAC equipment, or process lines where uninterrupted protection is critical.

• Three‑pole construction ensures synchronized protection across all phases, reducing the risk of unbalanced faults.
• 600‑volt rating accommodates mid‑to high‑voltage distribution environments, expanding its use from larger commercial to industrial applications.
• Part of the Square D family, offering consistent mounting, panel compatibility, and straightforward replacement in existing installations.
• Clear, specific spec set (HGA36015AA) simplifies ordering and cross‑referencing when maintaining a panel bank.

Use cases and scenarios:

• New installations in 3‑phase distribution panels where motor loads or process equipment require robust overcurrent protection.
• Upgrading legacy 3‑pole 600 V breakers to a standard Square D component for easier sourcing and serviceability.
• Replacement in manufacturing lines, warehouses, or other facilities with 3‑phase power infrastructure to minimize downtime.

Practical tips:

• Verify panel compatibility with the HGA series and confirm bus compatibility before installation.
• Keep spare HGA36015AA units on hand for rapid replacements to minimize downtime.
• Document the exact part number when ordering replacements to ensure consistent current rating and trip characteristics.
