Square D QO215CP - 15 A, 240 V, 2-Pole Plug-In Circuit Breaker | AmpState

The Square D QO215CP is a 15 A, 240 V, 2-pole plug-in molded case circuit breaker built to safeguard your panelboards and load centers from overcurrent and short-circuit events. Designed for quick, dependable protection, this breaker slides into compatible Square D QO-style load centers for fast upgrades, replacements, or new installations.

Why this breaker stands out

• Fast plug-in connection for quick installation and simple, tool-free replacements, reducing downtime during maintenance or panel upgrades.
• Thermal-magnetic trip unit delivers stable, repeatable protection by efficiently handling both overloads and short circuits, helping prevent nuisance trips while ensuring safety.
• 2-pole, 240 V configuration provides simultaneous disconnection of both conductors, ideal for sharing 240 V circuits and maintaining coordinated protection across connected appliances or equipment.
• OEM-compatible design works with matching Square D load centers and panelboards, simplifying stocking and installation when upgrading or expanding an electrical system.
• Versatile for multiple settings suitable for residential panel upgrades, light commercial applications, and select industrial environments that rely on robust branch circuit protection.

What problems does it solve?

When a circuit is overloaded or experiences a short circuit, the QO215CP automatically interrupts current flow to prevent overheating, component damage, or electrical fires. The dual-pole design ensures both legs of a 240 V circuit trip together, preserving safety and preventing dangerous partial outages. This plug-in solution minimizes downtime and streamlines service work, making it an effective choice for both new installations and field replacements.
