Meet the Square D QOBXD120 20A 1-Pole 240 V Circuit Breaker — a precise, dependable protective device built to safeguard 240-volt branch circuits in Square D panels. With part number QOBXD120, this breaker is designed to slot into compatible Square D installations, delivering reliable over‑current protection when you need it most.

  • Exact specs for confident protection: 20‑amp current rating, 1‑pole configuration, 240 V maximum rating. This specific combination is ideal for dedicated 240V loads where precise protection is essential.
  • Easy replacement in existing systems: The QOBXD120 is engineered to fit the same footprint and engagement as compatible Square D panels, making swaps straightforward and minimizing downtime during service or upgrades.
  • Trusted brand with compatible ecosystem: From Square D (Schneider Electric), this breaker aligns with other Square D devices and accessories, helping you maintain a cohesive, reliable protection system.
  • Consistent, dependable performance: Designed to provide dependable protection for 240V circuits, helping prevent damage from overloads and short circuits while maintaining smooth operation of connected equipment.

Ideal use cases

This 20A, 1-Pole 240V breaker is well suited for 240V branch circuits in residential or light commercial settings that require a dedicated 20A protection device. It’s a practical choice for replacing a failing breaker in existing Square D panels or stocking up as a reliable spare for service technicians who support 240V systems and equipment.

Practical tips: confirm panel compatibility with Square D QO/QOBXD Series breakers, ensure proper torque and installation per panel instructions, and verify that your wiring gauge aligns with a 20A protection requirement (typically #12 AWG copper or as specified by your panel’s guidelines). For any installation, ensure power is fully isolated and, when in doubt, consult a licensed electrician.
