• Safeguarding HVAC equipment and large compressors in commercial buildings.
• Integrating into electrical distribution panels that require reliable 3‑pole protection at up to 600 V.

How it helps your operation

• Quick, reliable interruption during overloads or short circuits minimizes equipment damage and downtime.
• Three‑pole design ensures balanced protection across all phases, reducing arc flash risk and improving overall electrical safety.
• Built to withstand the rigors of industrial environments, offering long service life in panelboards and switchgear assemblies.

Installation and compatibility tips

Before integrating this breaker, verify compatibility with your Square D panelboard and bus arrangement. Follow standard wiring practices for 150 A devices, use recommended conductor sizes, and torque connections to the manufacturer’s specifications. As with all high‑voltage protective devices, ensure the power is de‑energized during installation and consult your panel’s documentation for any model‑specific installation notes.

Maintenance and care

Periodically inspect for signs of wear, corrosion, or physical damage. If the breaker exhibits sticking, abnormal tripping, or signs of overheating, replace it with an equivalent HGA series unit to maintain system protection and reliability.
