Square D QOB330EPD 30A 3-Pole 240 V Circuit Breaker

Meet the Square D QOB330EPD 30A 3-Pole 240 V Circuit Breaker—the dependable protection your 240-volt, three‑phase or multi‑wire electrical systems deserve. With a 30-amp rating across three poles, this breaker interrupts current on all live conductors, helping prevent damage from overloads, short circuits, and electrical faults before they impact equipment or safety.

• Current rating: 30 A
• Poles: 3
• Voltage rating: 240 V
• Part number: QOB330EPD

The QOB330EPD is purpose-built for reliability in demanding environments where heavy loads drive motors, compressors, and other 240V equipment. Its three-pole design ensures synchronized interruption across all conductors, enhancing protection for 3‑phase machines and reducing the risk of fault propagation that can occur with single- or two-pole breakers.

Why choose this model? It provides precise, consistent protection for 240V circuits while simplifying inventory and replacement planning thanks to a clearly identified part number (QOB330EPD). By safeguarding three essential conductors at once, it helps minimize downtime and maintenance costs in commercial and industrial settings.

Ideal use cases include industrial machinery, HVAC drives, large air compressors, and other equipment that requires robust 3‑pole, 240V protection. If your installation relies on a dedicated 240V, three‑pole circuit, the Square D QOB330EPD is designed to meet that need with dependable performance.

When planning an upgrade or replacement, consider this model for its clear specifications and reliable operation in Square D environments. For installations demanding solid overcurrent protection across three conductors, the QOB330EPD delivers a targeted, practical solution—aligning with your 240V system requirements and component compatibility considerations.
