• Current rating: 150 A
• Poles: 3
• Voltage rating: 600 V

What makes this breaker unique

Designed for three-phase distribution, this 3-pole breaker provides synchronized protection across all conductors—crucial for balanced load and minimized fault propagation in motor feeds and complex electrical panels. The 150 A rating targets mid-to-high load circuits, making it a precise fit for industrial equipment, large HVAC feeders, and other demanding applications. As a Square D component, it benefits from proven reliability, consistent trip performance, and straightforward integration into compatible Square D panels and enclosures.

Ideal use cases

• Three-phase motor feeders in manufacturing and processing facilities
• Industrial equipment panels and machine control centers
• Commercial distribution panels operating with 600 V systems

Benefits and practical considerations

• Coordinated protection across all three phases reduces the risk of unbalanced faults and downstream damage
• Compact, plug-and-play form factor designed for standard Square D enclosures
• Clear, specific part identification (HGA36150UOYP) to simplify stocking and replacements

Practical tips: When installing or replacing, verify panel compatibility and follow manufacturer torque and mounting guidelines. Ensure system wiring, insulation, and terminations are rated for 600 V and 150 A to maintain safe, reliable operation.
