Square D QOU210 - 10 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Square D QOU210 — a 10A, 240V, 2-pole bolt-on circuit breaker built for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. This molded-case breaker is engineered to stay secure and perform consistently under real-world conditions.

Why this breaker stands out

• Secure bolt-on mounting delivers a rigid, vibration-resistant connection to the bus, reducing movement that can lead to wear or arcing over time.
• Thermal-magnetic trip unit provides stable, repeatable protection—thermal action responds to sustained overloads, while magnetic action rails against sudden short circuits for fast isolation.
• OEM-compatible design is matched to Square D load centers and panelboards, ensuring a reliable fit and straightforward replacement in existing systems.
• Durable molded-case construction supports long-term reliability in mission-critical electrical panels, across residential, commercial, and light industrial settings.
• 2-pole, 10A, 240V configuration protects both hot conductors in typical 240V circuits, ideal for branch circuits feeding lighting, receptacles, or modest equipment loads.

Who should consider the QOU210

• Electricians performing panel maintenance or replacements in residential projects, multi-residence builds, or light commercial installations.
• Technicians updating older panelboards to ensure consistent protection against overcurrent and short circuits.
• Facility managers seeking durable, compatible components that align with existing Square D equipment.
