Square D HGA36100U44XAABCSD 100A 3-Pole 600 V Circuit Breaker

Square D HGA36100U44XAABCSD delivers reliable overcurrent protection for three‑phase power systems. This 100A, 3‑pole circuit breaker is engineered to interrupt fault currents quickly and safely, safeguarding wiring, motors, and downstream equipment in industrial and commercial applications. With a 600 V rating, it fits a wide range of distribution panels and control gear, making it a dependable choice for demanding power environments.

Why this specific breaker stands out

• Three-pole configuration ensures simultaneous disconnection of all live conductors in a 3‑phase circuit, preventing dangerous phase-to-phase faults and reducing equipment damage.
• 100 ampere rating provides robust protection for demanding motors, feeders, and heavy-duty loads while minimizing unnecessary trips during normal startup surges.
• 600 V maximum voltage rating expands its applicability across industrial installations, helping you meet safety and performance requirements in higher‑voltage environments.
• Distinct part number HGA36100U44XAABCSD guarantees compatibility with Square D panels and a standardized replacement path, simplifying ordering and serviceability.
• Built to endure typical industrial conditions, offering dependable trip performance when faults occur and contributing to safer, more predictable power distribution.

Ideal use cases

Perfect for three‑phase motor circuits, conveyors, processing equipment, and large feeders in manufacturing facilities, warehouses, and other environments powered by 3‑phase 600 V systems. It’s an excellent replacement option for aging breakers or for configuring new Square D panel layouts where precise 100 A, 3‑pole protection is required.

Practical considerations and tips

• Confirm panel compatibility with HGA series breakers and ensure the 3‑pole, 600 V configuration aligns with your distribution design.
• For reliable terminations, use appropriate conductor sizes for 100 A applications and follow the manufacturer’s torque specifications during installation.
• Keeping a field-ready unit on hand can reduce downtime during maintenance or panel upgrades, providing a quick swap for fault protection continuity.

With the Square D HGA36100U44XAABCSD, you invest in precise, dependable protection that supports safe operation and minimizes risk across your three‑phase electrical infrastructure.
