Square D QDL22250 - 250 A, 2-Pole Circuit Breaker | AmpState

Meet the Square D QDL22250, a 250A, 2-pole molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built by a trusted name in electrical safety, this device blends robust protection with space-efficient design to support residential, commercial, and light industrial setups.

Why this breaker stands out

• Compact molded case design maximizes panel space without sacrificing protection, making it ideal for tighter electrical enclosures or evolving panel layouts.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance. The thermal element guards against gradual overheating, while the magnetic element provides fast response to short circuits, helping minimize damage to wiring and devices.
• 2-pole configuration designed for typical two-phase circuits, enabling coordinated protection across both conductors in a shared enclosure.
• OEM-compatible engineered to be compatible with matching Square D OEM load centers and panelboards, ensuring reliable fit and electrical integrity.
• Versatile application suitable for residential environments, commercial spaces, and light industrial installations where dependable protection is essential.

What it does for you

The QDL22250 protects downstream wiring and equipment from overcurrent conditions and short circuits. When a fault is detected, the device automatically interrupts the circuit to prevent overheating, insulation damage, or fire risk. Its dual-mode trip mechanism means you benefit from both long-term overload protection and immediate disconnection during high-magnitude faults, preserving system reliability and safety.
