• Manufacturer: Square D (Schneider Electric)

Why this model is a smart choice

Designed for three-phase environments, the HDA36090SRYP ensures synchronized interruption across all three conductors, protecting wiring, motors, and control circuitry. Its 90 A rating makes it suitable for mid-size industrial equipment and commercial power distribution where reliable, consistent protection is essential. Being part of the Square D lineage, it integrates smoothly with Square D panels and enclosures, helping maintain a cohesive, easily serviceable electrical system.

Ideal applications

• Three-phase power distribution in workshops, manufacturing lines, and industrial facilities
• Motor control centers and equipment rooms requiring robust 3-pole protection
• Commercial electrical panels that rely on standard Square D components for easy maintenance

Protection and performance in real-world use

In the event of an overload or short circuit, the HDA36090SRYP rapidly interrupts current to minimize thermal stress on conductors and connected equipment. This helps reduce downtime, extend service life for motors and drives, and simplify compliance with safety standards in demanding environments.

Installation and care tips

• Verify system voltage and phase configuration match the 600 V, 3-pole specifications before installation
• Ensure secure mounting in compatible Square D panels and tighten terminals to the recommended torque
• Follow all applicable electrical codes and manufacturer guidelines during wiring and commissioning
