Square D | QGL22150 | Circuit Breaker | 150A | 2-Pole | 240V

Meet the Square D QGL22150 Circuit Breaker — a purpose-built, authentic Square D protection device crafted for demanding 240V circuits. With a 150A rating and 2-pole configuration, it’s designed for maintenance, retrofit, and replacement projects where exact specifications are non-negotiable. The QGL22150 is the reliable choice when you need a precise fit in panels that accept Square D QGL breakers.

• Amperage: 150 A
• Poles: 2-Pole
• Voltage: 240 V
• Part reference: QGL22150

Who benefits from this specific model? electrical professionals and facility owners who work on service panels or subpanels that require a 150A, 2-pole 240V breaker in the Square D QGL family. It’s an ideal choice for protecting large feeders or main circuits where reliable startup and predictable protection are essential for minimizing downtime and electrical risk.

Why choose an OEM QGL breaker over a non-specific substitute? The QGL22150 is engineered to align with Square D panels that accept QGL-type devices, ensuring proper fit, consistent trip performance, and straightforward installation. This isn’t a generic replacement — it’s a direct-match component designed to maintain the safety and reliability of your electrical system.

Important note: before ordering, confirm fit and ratings for your application. The part number is the best reference for compatibility, and matching the old device’s amperage, pole count, and voltage will help ensure a smooth replacement that preserves your circuit protections.

Practical tips for use and installation:

• Verify that your panel accepts QGL-type breakers and that the 2-pole 150A 240V configuration matches your circuit needs.
• When replacing, use the exact part number (QGL22150) to avoid incompatibility and ensure proper mounting and electrical contact.
• Always de-energize the panel and follow safety procedures before performing any replacement or maintenance work.
