Square D HGA260901AA 260901A 2-Pole 600 V Circuit Breaker

Introducing the Square D HGA260901AA 2-Pole 600 V Circuit Breaker — a purpose-built protection device designed for two-hot-leg circuits in commercial and industrial electrical systems. Identified by part number HGA260901AA and model reference 260901A, this breaker is built to deliver dependable overcurrent protection where it matters most.

Key characteristics at a glance:

• Two-pole design protects both hot conductors of a circuit, ensuring simultaneous disconnection to prevent backfeed and equipment damage.
• 600 V maximum voltage rating suitable for medium- and high-voltage distribution in commercial and industrial applications.
• Square D/HGA family compatibility designed to install into panels and enclosures that accept HGA-series breakers, offering a straightforward upgrade path for existing Square D installations.
• Reliable performance in demanding environments built to withstand routine circuit protection tasks in panels, feeders, and motor circuits.
• Clear part identification listed as HGA260901AA / 260901A for easy ordering and inventory management.

Use cases and practical applications:

• Feed and protect two-hot-leg circuits in commercial panels, service panels, or industrial switchgear that operate up to 600 V.
• Motor and equipment circuits where dual-pole protection helps shut down both legs together, reducing risk of partial energization.
• Retrofit projects where HGA-series breakers are specified to maintain panel labeling and replacement compatibility.

Why choose this Square D 2-Pole 600 V breaker over other options? It delivers the right combination of compatibility (HGA-series), voltage rating, and dual-pole protection in a compact form factor designed for two-conductor circuits. For technicians and facility managers, it provides a clear, straightforward path to maintain electrical safety and system reliability without guesswork when upgrading or stocking parts.

If you’re planning an installation or replacement, ensure the panel accepts HGA-series breakers and that the circuit requirements align with a 2-pole, 600 V solution. The HGA260901AA (260901A) is the dedicated choice when you require robust two-pole protection in Square D environments.
