Square D HGA36110AABCSD 36110A 3-Pole 600 V Circuit Breaker

Square D HGA36110AABCSD is a rugged 3-pole circuit breaker engineered for demanding 3‑phase power distribution. With a 600 V voltage rating and a specified current rating of 36110 A, this unit provides decisive fault protection for industrial and commercial electrical systems while helping keep panels running smoothly under heavy loads.

Designed for three‑phase protection, the 3-pole configuration ensures simultaneous tripping of all conductors when a fault is detected. This coordinated response reduces arc energy, minimizes equipment damage, and simplifies protection planning in motor drives, feeders, and distribution panels.

Key specifications at a glance:

• Part Number: HGA36110AABCSD
• Poles: 3
• Voltage Rating: 600 V
• Current Rating: 36110 A
• Brand: Square D

This model is ideal for environments where reliable three‑phase protection matters—industrial control panels, commercial power distribution, and critical equipment feeders that rely on consistent, coordinated shutdowns during fault conditions. Its Square D lineage underscores a long-standing commitment to robust electrical protection, compatibility with Square D panels and enclosures, and dependable performance in everyday industrial workflows.

Practical use cases include protecting large three‑phase motors, processing lines, and distribution feeders in manufacturing settings, as well as safeguarding panelboard sections that serve high‑demand loads. When compared with single‑ or dual‑pole solutions, the HGA36110AABCSD provides a more comprehensive safeguard for all three phases, helping you maintain system integrity and reduce downtime.

Tips for getting the most out of this breaker: verify the breaker’s compatibility with your Square D enclosure and panel type, ensure correct mounting and torque per manufacturer guidelines, and have a qualified electrician perform installation and testing. Pair it with appropriate overcurrent protection and labeling to support safe, ongoing operation of your three‑phase electrical system.
