Why this 3-pole breaker matters

In three‑phase systems, the ability to shut down all three phases simultaneously is critical for safety and equipment protection. The HGA36090UAYP delivers coordinated disconnection across all poles, helping prevent phase imbalances, overheating, and potential damage to motors and feeders when a fault occurs. Its 90 A rating makes it well-suited for intermediate to heavier three‑phase loads typical in commercial spaces, industrial equipment, and process lines operating at up to 600 V.

Use cases and ideal applications

• Protection for three‑phase feeders feeding motors, pumps, and conveyors in manufacturing or processing environments
• Distribution panel protection in light to mid‑scale industrial facilities
• HVAC machinery, chiller plants, and large mechanical systems that require reliable phase protection
• Retrofits or upgrades in panels that specify HGA series breakers for compatibility and performance

What makes it stand out

This breaker isn’t a generic safety device—it’s a precise, plug‑in component designed to fit Square D panels that accept HGA breakers, ensuring consistent performance and straightforward replacement. By choosing the HGA36090UAYP, you’re selecting a part that aligns with existing protection strategies, helps maintain service continuity, and supports safe, code‑compliant shutdown of critical equipment.

Installation and practical tips

• Ensure the panel is compatible with HGA series breakers before installation
• Follow all manufacturer torque specifications and mounting guidelines for secure, reliable connection
• Verify the circuit maps and labeling after installation to reflect the new protection device
• For ongoing safety, replace only with the same rating and configuration if a fault triggers a trip
