Square D HDA36090SVYP 90A 3-Pole 600 V Circuit Breaker

Meet the Square D HDA36090SVYP — a purpose-built solution for safeguarding three-phase electrical systems. With a 90 A current rating, 3 poles, and a 600 V voltage rating, this circuit breaker is designed to interrupt fault currents quickly, protecting both equipment and personnel in demanding environments.

The HDA36090SVYP is purposefully configured to handle everyday industrial loads while providing reliable isolation across all three phases. Its 3-pole design ensures coordinated protection, reducing the risk of unbalanced faults and minimizing downtime in process lines, HVAC systems, and manufacturing equipment.

Key benefits

• 3-pole protection ensures simultaneous disconnection of all conductors in three-phase circuits, improving system safety and fault handling.
• 90 A capacity is well-suited for medium-sized equipment and loads, offering robust protection without unnecessary nuisance tripping.
• 600 V rating makes it appropriate for industrial distribution and control panels where higher voltage circuits are present.
• Reliable integration with Square D panels and compatible enclosures, streamlining replacement and upgrades within existing electrical infrastructure.
• Consistent protection across phases helps minimize downtime and equipment wear by preventing cascading faults.

Ideal applications

• Industrial control panels and switchgear assemblies
• Motor control centers and heavy machinery distribution
• Commercial and light-industrial power distribution networks
• Three-phase systems in manufacturing, processing, and utility environments

Why this model stands out

The HDA36090SVYP is more than a breaker; it’s a targeted solution for three-phase protection in demanding settings. By delivering precise current handling at 90 A and a robust 600 V rating, it supports reliable operation of vital equipment while simplifying maintenance and upgrades in existing Square D ecosystems. It’s the practical choice when you need dependable, phase-coherent interruption for your three-phase circuits.

Practical considerations

• Verify compatibility with your panel or distribution system and confirm that a 3-pole, 600 V device matches your application requirements.
• Use proper installation practices and follow the panel manufacturer’s guidance to ensure secure mounting and electrical contact.
• When replacing an existing breaker, align the new unit with the same current rating and pole configuration to maintain system protection characteristics.
• Store and handle with care to prevent tip-over or damage to the breaker mechanism before installation.

For those upgrading or configuring three-phase power protection, the Square D HDA36090SVYP delivers clear, dependable protection with a focused specification set: 90 A, 3-pole, 600 V. Add it to your electrical toolkit to safeguard your equipment and keep your operations running smoothly.
