The Square D QO240CP is a 40-amp double-pole circuit breaker designed to protect electrical systems from overloads and short circuits. This breaker is engineered for use in QO load centers, QO enclosures, and NQOD panel boards, making it an ideal choice for homeowners and electricians who need reliable protection on demanding 240-volt circuits.

The QO240CP uses a thermal-magnetic tripping mechanism that reacts to both heat buildup and magnetic faults, ensuring fast and dependable fault clearing. An indicator makes it simple to identify a tripped breaker at a glance, saving time during troubleshooting.

Features and Benefits

  • Trip Indicator: Easily identify a tripped circuit breaker in the load center without opening the panel.
  • Thermal-Magnetic Protection: Dual-mode tripping responds to both gradual heat buildup and sudden magnetic faults for comprehensive circuit protection.
  • Two-Pole Common Trip: Both poles trip together when a fault is detected, shutting down the entire circuit safely.
  • Easy Installation: Plug-on design fits standard QO panel specifications for hassle-free replacement or upgrade.
  • 40-Amp Rating: Delivers reliable protection for demanding circuits.
