Product description
Shipping
Meet the Square D HRA36100U31XAABCSJ, a purpose-built circuit breaker engineered to protect three-phase power distribution in demanding industrial and commercial environments. With a 100 A rating, 3 poles, and a 600 V maximum voltage, this unit is designed to reliably interrupt fault current and isolate circuits to keep equipment safe.
- Part Number: HRA36100U31XAABCSJ
- Current rating: 100 A
- Poles: 3
- Voltage rating: 600 V
Why this configuration matters: In three-phase systems, a 3-pole breaker ensures all phases trip together, preventing unbalanced faults from causing overheating or damage to motors, drives, and other equipment. The 100 A rating is ideal for mid‑sized feeders and branch circuits that require solid protection without sacrificing performance.
Ideal use scenarios
- Three-phase distribution panels in industrial facilities powered by up to 600 V systems
- Commercial buildings with medium-current feeders that demand precise protection at 100 A
- Replacement or retrofit in existing Square D installations to maintain compatibility and system integrity
Why choose this specific model: The HRA36100U31XAABCSJ is a direct-fit solution for panels and applications designed around Square D’s HRA-style, 3-pole, 600 V circuit breakers. Its exact configuration simplifies selection, reduces compatibility risk, and supports consistent protection across your electrical infrastructure. As a trusted Square D device, it pairs with decades of protection engineering to deliver reliable performance in everyday operations and during fault events.
Practical considerations and insights
- Confirm panel compatibility: this part number is formulated for Square D installations requiring a 3-pole, 100 A device for 600 V circuits.
- Use case alignment: ideal for mid-range feeders and critical three-phase loads where reliable tripping behavior is essential.
- Maintenance mindset: keep spare units of the same configuration on hand to minimize downtime during replacements or panel upgrades.
