Square D HGA36100UJYP 100A 3-Pole 600 V Circuit Breaker

The Square D HGA36100UJYP 100A 3-Pole 600 V Circuit Breaker is engineered to protect three-phase electrical systems with precision and reliability. Designed around the HGA36100UJYP part, this unit delivers up to 100 amps of load current across three poles, handling demanding industrial and commercial applications with confidence.

Key benefits that matter in real-world panels

• Three-pole, synchronized protection: Ensures all three phases trip together, minimizing the risk of unbalanced loads and electrical faults in three-phase circuits.
• 100A capacity: Adequately protects feeders and branch circuits in medium-duty distributions while accommodating typical motor and equipment loads.
• 600 V maximum rating: Suitable for higher-voltage distribution environments common in industrial and large commercial setups.
• Direct part compatibility: Part number HGA36100UJYP aligns with Square D panels and retrofit applications where this exact specification is required.
• Reliability and compatibility: Built to serve as a dependable replacement or upgrade component in established Square D electrical systems.

Ideal use cases

• Protecting three-phase feeder circuits in industrial equipment rooms, manufacturing lines, or processing plants.
• Serving as a main or sub-feed protective device in commercial distribution panels that handle three-phase loads.
• Replacing a worn or failed breaker in existing Square D installations to restore safe, code-compliant protection.

Practical installation considerations

When selecting this breaker, verify that your panel is compatible with the HGA series and that a three-pole configuration is appropriate for the circuit being protected. For precise trip characteristics, wiring guidelines, and mounting details, consult the official product datasheet and follow all relevant electrical codes and safety standards.

Choose the Square D HGA36100UJYP when you need robust three-phase protection, a clear 100A limit, and a 600 V operating envelope in a single, reliable package. This is a purpose-built solution for dependable electrical protection in demanding power environments.
