Square D HGA36070SK 70A 3-Pole 600 V Circuit Breaker

The Square D HGA36070SK 70A 3-Pole 600 V Circuit Breaker is a purpose-built protective device designed for three-phase circuits in commercial and industrial environments. With a 70 A rating across three poles and a 600 V maximum, it’s engineered to interrupt fault currents reliably and safeguard your equipment.

• Part Number: HGA36070SK
• Current rating: 70 A
• Poles: 3
• Voltage rating: 600 V

Why this model matters

• Three-pole design provides coordinated protection across all three phases, which is essential for balanced loads such as motors, compressors, and conveyors.
• 600 V capability makes it suitable for higher-voltage commercial and light-industrial distribution networks.
• Square D reliability—optimized to work within Square D panels and enclosures, offering consistent performance and easier maintenance across your protection system.

Ideal use cases

• Protect 3-phase motors, pumps, and HVAC equipment in commercial or light-industrial settings.
• Replace worn or failed breakers in existing Square D panels that accept HGA-series devices.
• In new installations, provide 3-phase protection up to 70 A with a trusted Square D component in the protection lineup.

Practical notes

Ensure the panel you’re working with is compatible with HGA-series breakers and follow all manufacturer instructions during installation. This part is specifically suited for applications that require a 70 A, 3-pole protection device rated up to 600 V, aligning with your existing Square D gear for a cohesive protection strategy.
