Square D HGA36040AABCSH 36040A 3-Pole 600 V Circuit Breaker

Introducing the Square D HGA36040AABCSH — a robust 3-pole circuit breaker engineered for demanding electrical systems. With a 600 V maximum rating and a current rating of 36040 A, this unit is built to deliver reliable overcurrent protection for three-phase applications where uptime matters.

• Part number: HGA36040AABCSH
• Poles: 3
• Voltage rating: 600 V
• Current rating: 36040 A

The Square D HGA36040AABCSH stands out by delivering deliberate, phase-balanced protection for three-phase circuits. Its design focuses on maintaining system integrity in environments with high electrical loads, helping prevent damage to motors, transformers, and feeders when faults occur. This is a clear, purpose-built solution for installations where heavy-duty protection is essential.

• Protect large three-phase motors, conveyors, pumps, and other heavy loads in industrial facilities; suitable for commercial electrical rooms handling substantial three-phase demand; and appropriate for retrofit projects needing a 3-pole, 600 V breaker.
• What problems it solves: Reduces the risk of cascading faults in three-phase systems, minimizes downtime from overloads, and provides a clear, reliable path to tripping when faults arise.

• Practical tips: Before replacement, confirm that the panel and wiring are compatible with a 3-pole, 600 V device; keep a spare on hand to shorten maintenance windows; and follow standard electrical safety practices during installation and inspection.
