Square D HGA36100URYP 100A 3-Pole 600 V Circuit Breaker

Introducing the Square D HGA36100URYP 100A 3-Pole 600 V Circuit Breaker — a purpose-built protector for 3‑phase electrical systems. With a 100 A rating and three poles, this breaker is designed to reliably interrupt fault currents and shield wiring, panels, and connected equipment in commercial and industrial environments. Built to work with Square D installations, it offers seamless integration into compatible panel boards and enclosures.

Key specifications

• Current rating: 100 A
• Poles: 3
• Voltage rating: 600 V
• Part number: HGA36100URYP
• Brand: Square D

Why this matters

In a 3‑phase distribution network, protecting feeders and motors from overloads and short circuits is critical to minimize downtime and damage. The HGA36100URYP provides robust, line-side protection for circuits up to 600 V, ensuring that faults are isolated quickly and safely. Its three‑pole design means simultaneous interruption of all phases, which helps prevent circulating currents and ensures stable protection for motors, transformers, and other three‑phase equipment.

Ideal use cases

• Protection for 3‑phase feeders in commercial and industrial panelboards and switchgear.
• Replacement part in existing Square D installations where a 3‑pole, 100 A, 600 V solution is required.
• Protection for motor circuits, compressors, pumps, and other 3‑phase loads operating up to 600 V.
• Distribution panel protection in facilities with compact or space-conscious electrical layouts.

Compatibility and installation tips

• Ensure the breaker is used with compatible Square D panels or enclosure systems that support the HGA series.
• Verify that the circuit’s voltage and current requirements align with the 600 V / 100 A rating of the device.
• Install per manufacturer guidelines and follow all local electrical codes. When mounting, refer to the panel’s installation instructions for proper torque and alignment.
• Keep the application within its intended environment to maintain reliable operation and longevity.

The Square D HGA36100URYP 100A 3-Pole 600 V Circuit Breaker is a targeted solution for safeguarding three‑phase power systems, delivering clear protection for critical equipment while supporting smooth, continuous operation in demanding electrical settings.
