Meet the Square D QGL32090 Circuit Breaker — a 90 Amp, 3-Pole device designed for reliable protection in 240-volt, three-phase systems. Built for maintenance, retrofit, and replacement projects, it plugs into compatible Square D panels where exact specifications matter. Before you order, confirm fit and ratings; the part number is the best reference for compatibility.

Key specifications

• Amperage: 90A
• Poles: 3-Pole
• Voltage: 240V
• Interrupting capacity: 65 kA
• Part number: QGL32090

Why choose this Square D QGL32090 breaker

This breaker is built to drop into systems that require a QGL-type 3-pole unit, delivering precise overload protection for 240V distribution. The 90A rating makes it well-suited for safeguarding motor loads, commercial equipment, and moderate-duty circuits, while a robust 65 kA interrupting rating adds a safety margin for fault currents typically seen in commercial environments.

Use cases and compatibility

Ideal for:

• Maintenance on existing panels that specify QGL32090 or compatible QGL-type breakers
• Retrofits where a precise 3-pole, 240V, 90A breaker is required
• Replacement of failed breakers in 3-phase 240V circuits in light to moderate industrial settings

Important: Confirm fit and ratings before ordering. The part number is the best reference for compatibility with your panel or load center.

Installation and safety tips

For safe installation, ensure the main power is de-energized and follow local electrical codes. Use the correct bus connection and torque values as specified by your panel’s instructions, and verify alignment with the QGL family. If you’re unsure, consult a licensed electrician to confirm compatibility with your enclosure and perform the installation.
