Square D HRA36100U31XAABCSJYP 100A 3-Pole 600 V Circuit Breaker

Introducing the Square D HRA36100U31XAABCSJYP, a purpose-built 100 A, 3-pole circuit breaker designed to protect three-phase electrical systems up to 600 V. With its precise 3-pole configuration, this unit delivers reliable overcurrent protection across all three phases, keeping motors, feeders, and commercial electrical circuits safeguarded from faults and overloads.

• Model and series: Square D HRA36100U31XAABCSJYP (HRA series)
• Current rating: 100 A
• Pole configuration: 3-pole
• Voltage rating: Up to 600 V
• Purpose: Provides three-phase overcurrent protection for panels, feeders, and distribution circuits

This circuit breaker is ideal for industrial and commercial electrical environments where three-phase power is standard—think panel boards serving manufacturing lines, HVAC systems, data centers, and large office complexes. By isolating faults quickly and predictably, it minimizes downtime and protects wiring, equipment, and people.

Key benefits that set this unit apart include its exact fit for Square D panel systems and its ability to coordinate with other protective devices in a three-phase network. The 100 A rating makes it suitable for mid-sized distribution segments, while the 3-pole design ensures synchronized protection across all phases, reducing the risk of unbalanced faults.

Practical tips for use: - Verify panel compatibility and ensure the enclosure supports 600 V devices and 3-pole breakers. - When replacing older equipment, confirm the replacement part number aligns with your Square D system to maintain protection coordination. - Use in conjunction with appropriate wiring gauges and conductors rated for up to 600 V and the target current, to maximize protection and longevity of downstream equipment.

In short, the Square D HRA36100U31XAABCSJYP is a robust, industry-standard solution for reliable three-phase protection at 600 V, delivering precise current protection with a straightforward path to installation in compatible Square D panels.
