Square D HGL36090UA 90A 3-Pole 600 V Circuit Breaker

Meet the Square D HGL36090UA 90A 3-Pole 600 V Circuit Breaker—a purpose-built safeguard for demanding three-phase power systems. With a 90 A current rating, a 3-pole configuration, and a 600 V maximum rating, this breaker delivers reliable protection for medium to high-load industrial and commercial circuits. Part number HGL36090UA is your clear, direct reference for replacement or specification in panels that accept Square D devices.

Key benefits and what they mean for your electrical system:

• Three-pole protection—protects all three phases simultaneously, helping ensure balanced protection across the circuit and reducing the risk of phase-to-phase faults.
• 90 A current rating—handles substantial loads such as motor feeders, drives, and other heavy equipment without nuisance interruptions, supporting steady operation.
• 600 V maximum rating—suitable for typical industrial distribution networks and equipment operating up to 600 V, providing versatile compatibility across applications.
• Square D compatibility—designed to integrate with standard Square D panels and configurations, simplifying installation and future maintenance within existing electrical systems.
• Reliability in challenging environments—built to maintain dependable protection in commercial and light-industrial settings, helping minimize downtime and protect both equipment and personnel.

Ideal use cases:

• Three-phase motor feeders for manufacturing lines, conveyors, and machine tools.
• Industrial HVAC, pumps, and process equipment requiring robust, coordinated protection.
• Main or feeder breakers inside electrical panels where 3-phase, 90 A protection up to 600 V is necessary.

Practical considerations:

• Ensure your panel is compatible with HGL-series Square D breakers and that wire sizing and protection match the 90 A rating.
• Install in accordance with local electrical codes and manufacturer guidelines; consult a licensed electrician if you’re unsure about panel compatibility or wiring requirements.
