Square D HLA36040AABCSDYP 36040A 3-Pole 600 V Circuit Breaker

Meet the Square D HLA36040AABCSDYP, a robust 3-pole circuit breaker designed to protect three-phase electrical systems in demanding environments. Built by Square D, this unit delivers reliable interruption at a 600 V rating for safe, swift disconnection when fault conditions occur. The model is identified by Part Number HLA36040AABCSDYP and is associated with the 36040A family, optimized for serious industrial use.

• Part Number: HLA36040AABCSDYP
• Current rating: 36040 A
• Poles: 3
• Voltage rating: 600 V
• Configuration: 3-Pole circuit breaker for three-phase power

In three-phase distribution, equipment and motors rely on precise protection. This Square D breaker acts as the first line of defense against overloads and short circuits, preventing insulation damage, conductor overheating, and unplanned downtime. When the current exceeds safe levels, the unit trips to isolate the circuit, helping protect costly machinery and keep your operation running smoothly.

Ideal use cases

• Industrial control panels and switchboards that require a 3-pole, 600 V protection device
• Three-phase motors, conveyors, pumps, and processing lines where reliable protection is critical
• Panel retrofits or replacements that need a genuine Square D component matched to HLA-series form factors

Why this model stands out

• Authentic Square D construction ensures compatibility with Square D enclosures and upstream protection schemes
• Three-pole design provides balanced protection across all phases in three-phase circuits
• 600 V rating makes it suitable for mid- to high-voltage industrial distribution networks
• Part of the HLA36040AABCSDYP family, offering a precise fit for existing installations that specify this exact part number

Practical tips for installation and use

• Verify that your panel or bus assembly accepts 3-pole breakers of this configuration and voltage rating before replacement
• Match the current rating and trip characteristics to the protected load (motors, feeders, or other equipment) and consult your panel’s documentation
• When replacing, ensure proper alignment and secure mounting to maintain reliable electrical contact and safe operation
• Keep a record of part number HLA36040AABCSDYP for future maintenance or replacement planning
