Square D HLA36100USYP 100A 3-Pole 600 V Circuit Breaker

The Square D HLA36100USYP 100A 3-Pole 600 V Circuit Breaker is built to protect three‑phase electrical systems from overcurrent with precision and reliability. Bearing the part number HLA36100USYP, this device is designed for demanding commercial and light industrial environments where consistent protection of motors, feeders, and distribution circuits matters most.

• Three-pole configuration provides balanced protection across all phases, reducing the risk of unbalanced faults damaging equipment.
• 100 A current rating delivers robust overcurrent protection for typical three-phase loads, including motors, pumps, and processing equipment, while helping prevent nuisance trips on normal startup surges.
• 600 V voltage rating supports higher-voltage distribution networks common in industrial settings, enabling safer and more efficient panel design for large machinery and drives.
• Part number clarity HLA36100USYP simplifies ordering, inventory management, and cross-referencing within Square D’s circuit breaker ecosystem.
• Brand assurance from Square D, a trusted name in electrical protection known for enduring performance in demanding installations.

This circuit breaker is ideal for facilities that rely on dependable three-phase protection, such as manufacturing floors, HVAC compressor banks, water treatment facilities, and data center infrastructure where three-phase power feeds must be reliably interrupted during faults. Compared to single-pole solutions, this 3‑pole breaker provides comprehensive phase protection in one unified device, simplifying panel layouts and ensuring all phases trip together when a fault occurs.

Practical considerations to keep in mind: verify that your panel accepts HLA-series breakers, match the 600 V rating to your facility’s distribution, and ensure the 100 A rating aligns with the protected load’s continuous current and short-circuit requirements. Regularly inspect connections and verify trip functionality as part of routine electrical maintenance to maintain optimal protection for your equipment.
