How it protects your system

The thermal-magnetic mechanism combines two protection modes: thermal sensing for gradual overheating and magnetic tripping for immediate response to short circuits. This dual action minimizes long-term wear on wiring and devices while reducing the risk of downstream damage from overloads. With an 80 A rating and two-pole construction, it provides robust protection for higher-load circuits typically found in feeders or subpanels.

Ideal use cases

• Replacing aging or failed breakers in existing Square D panelboards and load centers
• Upgrading residential electrical panels to accommodate higher-capacity circuits
• Adding protection in light commercial subpanels and simple industrial setups
• Maintenance, service upgrades, or retrofit projects where OEM compatibility matters

Installation and compatibility tips

To ensure peak performance, install this plug-in breaker into compatible Square D OEM panels and load centers. Always verify that the panel’s catalog number and listing align with the HDA260802 conduit and electrical specifications. Use in circuits that match or fall below the 80 A rating, and confirm that the two-pole design is appropriate for your multi-wire circuits and shared neutrals.

With the Square D HDA260802, you gain a purpose-built solution that pairs quick installation with dependable protection. It’s a practical choice for electricians and DIYers tackling panel upgrades, upgrades to higher-capacity circuits, or routine maintenance—delivering clear, repeatable protection when it matters most.
