Square D HDA36080UKYP 80A 3-Pole 600 V Circuit Breaker

Square D HDA36080UKYP 80A 3-Pole 600 V Circuit Breaker is built to protect three-phase electrical circuits in demanding environments, delivering reliable overcurrent protection for up to 600 volts across three conductors. This unit carries the part number HDA36080UKYP and is the right choice when you need a compact, robust protection solution in industrial or commercial panels.

Key specifications

• Current rating: 80 A
• Poles: 3
• Voltage rating: 600 V
• Part number: HDA36080UKYP

What makes it unique

This 3-pole design consolidates protection for all three phases in a single device, simplifying panel layouts and wiring in three-phase systems. With an 80 A rating, it’s well-suited for medium-load circuits such as motors, pumps, and other equipment that require reliable protection without frequent trips. The 600 V rating provides headroom for industrial and commercial power distribution, helping you avoid nuisance trips in higher-voltage environments. Built on Square D technology lineage, this breaker is designed for consistent performance in daily operation.

Ideal use cases

• Three-phase motor circuits in manufacturing equipment, conveyors, and HVAC systems
• Branch protection in commercial electrical panels serving heavy-load machinery
• Spare or replacement in existing Square D protection schemes, offering a straightforward upgrade path

Comparative thought

Compared to smaller, single-pole options or lower-volt devices, the HDA36080UKYP provides a unified protection solution for all three power phases, reducing wiring complexity and improving panel organization. It’s a practical upgrade for systems that require dependable trip characteristics at higher voltage levels.

Installation and safety tips

To ensure optimal performance, verify the breaker’s compatibility with your panel and follow manufacturer torque specifications during installation. Regularly inspect connections and ensure there is no corrosion or loose terminations that could compromise protection reliability.
