Square D HGA36100UO 100A 3-Pole 600 V Circuit Breaker

Meet the Square D HGA36100UO, a rugged three-pole circuit breaker designed for demanding 600-volt electrical systems. With a precise 100 A rating and the HGA36100UO part number, it delivers dependable protection for three-phase feeders in commercial and industrial panels where reliable interruption is essential.

Key features and benefits:

• Three-pole design provides true 3-phase protection, ensuring synchronized interruption across all phases.
• 100 amp current rating safeguards feeders and equipment up to 100 A, helping prevent overloads and electrical faults.
• 600 V voltage rating is suitable for distributing power in medium-voltage environments and a wide range of industrial applications.
• Part Number HGA36100UO enables exact ordering, replacement, and inventory management.
• Designed to fit Square D panels or systems that accept HGA-style breakers, making retrofit and panel upgrades smoother.

Ideal use cases include:

• Three-phase motor circuits and machinery in manufacturing facilities
• HVAC and processing equipment running on 600 V three-phase power
• Industrial distribution boards protecting feeders to large equipment and production lines

Why choose this Square D breaker over generic substitutes? It’s engineered to integrate with Square D’s protective device ecosystem, delivering consistent electrical characteristics and predictable trip behavior within a panel that expects HGA-type breakers. The 3-pole configuration ensures balanced protection across all phases, reducing the risk of unbalanced faults in 3-phase systems.

Installation and maintenance notes:

• Verify your panel is compatible with HGA-series breakers and that a 600 V system design is appropriate for your installation.
• Use the 100 A rating for circuits feeding motors, transformers, or heavy loads requiring robust three-phase protection.
• Keep the part number (HGA36100UO) on hand in spare parts inventories to ensure fast replacements when needed.

For reliable, consistent protection of 3-phase circuits up to 600 V and 100 A, the Square D HGA36100UO 3-Pole Circuit Breaker stands out as a precise, purpose-built choice for industrial electrical distribution.
