Square D QDL22200 - 200 A, 240 V, 2-Pole Circuit Breaker | AmpState

Square D QDL22200 – 200A, 240V, 2-Pole Molded Case Circuit Breaker (AmpState) is engineered to provide dependable branch circuit protection in panelboards and load centers. This compact, robust device is built to handle the demands of residential, commercial, and light industrial applications with precision and peace of mind.

Key to its performance is the thermal-magnetic trip unit, which combines reliable overload protection with fast magnetic response to short-circuits. That means fewer nuisance trips during everyday startups and a quick, decisive shutoff when fault conditions occur, safeguarding wiring, devices, and downstream equipment.

Designed with space efficiency in mind, the molded case construction keeps footprint small without sacrificing durability. Its 2-pole configuration and 200A rating make it ideal for main feeder protection or as a critical branch-circuit breaker within a panelboard or load center—helping you optimize panel density and maintain organized, code-compliant electrical layouts.

One of the standout benefits is OEM loadcenter compatibility. This breaker is formulated to work smoothly with matching Square D panels, delivering a seamless fit and dependable performance when replacing an aging unit or upgrading an existing system. The result is streamlined installation, fewer compatibility concerns, and lasting reliability across your electrical infrastructure.

Who should consider the QDL22200? It’s an excellent fit for:

• Residential service panels needing durable, space-efficient main or feeder protection
• Commercial lighting and power distribution boards that require stable overcurrent protection
• Light industrial panels where reliable short-circuit interruption is critical for equipment longevity

Practical use cases include upgrading aging breakers in legacy Square D systems, configuring new panels for new rooms or extensions, or replacing a failed 200A, 240V 2-pole unit to restore critical service quickly. When installing, follow standard electrical practices: verify panel compatibility, secure wiring with proper torque, and ensure the line/load orientation aligns with the panel’s labeling.
