Square D HLA36040AABCSJYP 36040A 3-Pole 600 V Circuit Breaker

Square D HLA36040AABCSJYP is a robust 3-pole, 600 V circuit breaker designed to protect three-phase electrical distribution in demanding industrial and commercial settings. Built with the exact configuration identified by the part number HLA36040AABCSJYP and model designation 36040A, this breaker delivers reliable interruption when overloads or short circuits occur, helping to safeguard equipment and personnel.

• Three-pole configuration provides synchronized protection across all phases, reducing the risk of phase imbalance and collateral damage in three-phase systems.
• 600 V maximum voltage rating suits higher voltage distribution and motor circuits common in industrial environments.
• Current rating listed as 36040 A, aligning with circuits requiring substantial protection for demanding loads.
• Part number HLA36040AABCSJYP ensures you’re selecting the exact Square D configuration for your panel.
• Square D reliability—a trusted name in electrical protection with a long heritage of safeguarding critical infrastructure.

This breaker is tailored for three-phase power protection in commercial and industrial panels, making it a strong fit for motor drives, HVAC equipment, pumps, and other heavy-load applications where reliable disconnection across all phases is essential for safety and uptime.

Why choose this model — compared to single-pole solutions, the 3-pole design guarantees coordinated tripping of all phases, helping prevent dangerous voltage spikes and equipment damage during fault conditions. The 600 V rating broadens compatibility with higher voltage distribution scenarios, while the explicit 36040 A current rating indicates its suitability for substantial load demands.

Practical guidance — verify panel compatibility with this exact part, and follow standard electrical installation practices for three-phase breakers. Use appropriate conductor sizes, secure terminations with correct torque, and replace if a trip has occurred to restore protective reliability.
