• Brand: Square D
• Poles: 3
• Voltage rating: 600 V
• Current rating: 36080 A

Why this 3‑pole design matters

Designed for three‑phase protection, the 3‑pole configuration ensures simultaneous disconnection of all phases, providing balanced, comprehensive protection for motors, conveyors, and other three‑phase equipment. This is especially important in industrial environments where reliable, coordinated protection reduces equipment damage and downtime.

Ideal use cases

• Three‑phase feeders in industrial power distribution panels
• Motor control circuits and machine enclosures requiring 600 V class protection
• Retrofits or replacements within Square D panel ecosystems to maintain system compatibility

What makes it stand out

• Exact part identity: The HJL36080AA designation ensures you’re selecting the precise Square D component for compatible panels and assemblies.
• Three‑phase reliability: A true 3‑pole design delivers coordinated interruption across all phases, reducing the risk of imbalanced faults.
• 600 V protection: Suitable for commercial and industrial environments where higher voltage circuits are common, delivering robust protection where it’s needed most.

Practical tips for optimal use

• Verify that your installation is within a 3‑phase, 600 V system and that the panel supports the HJL36080AA form factor.
• When replacing or upgrading, ensure you're matching the exact part number (HJL36080AA) to preserve panel compatibility and electrical protection continuity.
• Follow standard electrical safety procedures during inspection, replacement, or installation to protect personnel and equipment.
