Square D QOB250 - 50A, 2-Pole, Circuit Breaker

Meet the Square D QOB250 — a dependable 50A, 2-Pole Circuit Breaker crafted for demanding electrical environments. With a compact two-pole design, this unit offers flexible integration in panelboards, switchboards, and control panels, delivering reliable protection where it matters most.

• 50A current rating provides targeted overcurrent protection for individual circuits feeding motors, equipment, and branch circuits in distribution panels and motor control centers.
• 2-Pole configuration ensures simultaneous protection of both live lines, helping maintain balanced protection across your electrical system.
• Versatile installation suits panelboards, switchboards, and control panels across a range of installations in industrial, commercial, and OEM settings.
• Durable, trusted performance from a Square D solution designed for long-term operation in demanding environments where safety and reliability are paramount.
• Ideal for critical protection points in distribution networks and motor control centers, helping minimize downtime and protect valuable equipment.

What makes the QOB250 stand out

Unlike single-pole or lower-capacity breakers, the QOB250 offers robust, two-pole protection at a practical 50A rating, specifically addressing circuits that require dependable interrupting capability across both conductors. Its design aligns with the needs of panel assemblies and control architectures where space, reliability, and coordinated protection matter.

Optimal use scenarios

Designed for industrial, commercial, and OEM applications, the QOB250 is well-suited for:

• Protection in distribution panels and motor control centers
• Retrofits and new installations in panelboards and switchboards
• Systems where consistent, two-pole protection across both hot legs is essential

For best results, verify that your installation supports a 50A, 2-Pole circuit breaker in the target panel or MCC configuration. The QOB250 delivers reliable overcurrent protection with straightforward integration, helping you maintain safe operation and system uptime.
