Square D QO350EPD: 50A 240V 3-Pole Plug-In Circuit Breaker

Experience robust branch-circuit protection for panelboards and load centers with this plug-in molded-case breaker from Square D. The QO350EPD is engineered to endure daily electrical demands in residential, commercial, and light-industrial environments, delivering dependable protection when it matters most.

Key features that distinguish the QO350EPD:

  • Fast plug-in connection for quick installation or replacement, minimizing panel downtime and simplifying service work.
  • Thermal-magnetic trip unit provides stable, repeatable protection by combining a thermal element for overload detection with a magnetic element for rapid short-circuit response.
  • OEM-loadcenter compatibility ensures a reliable fit and coordinated trip characteristics with matching Square D QO panelboards and load centers.
  • Three-pole, 50A, 240V configuration supports three-phase circuits or multi-wire branches in a single protective device.
  • Plug-in mounting enables straightforward integration into compatible enclosures, reducing wiring complexity and installation time.

Ideal uses and real-world benefits

Use the QO350EPD to guard critical branch circuits in small to mid-size commercial spaces, residential panels with 240V circuits, or light-industrial installations. Its precise thermal-magnetic trip behavior translates to predictable protection during overloads and fast response during short circuits, helping protect both equipment and wiring from damage.

Beyond protection, the plug-in design supports easier maintenance and quicker upgrades. When panels require replacement or breaker swaps are needed, this unit delivers a clean, efficient retrofit that keeps projects on schedule.
