Square D HGA36100SVYP 100A 3-Pole 600 V Circuit Breaker

Square D HGA36100SVYP 100A 3-Pole 600V Circuit Breaker is a rugged protection device crafted for reliable safeguarding of three-phase power in commercial and light industrial settings. With a 100 A current rating and three poles, this breaker provides precise, predictable protection for large feeders and motor circuits while tolerating voltages up to 600 V.

Key advantages at a glance:

• Three-pole design for balanced three-phase protection — safeguards all phases simultaneously, helping prevent uneven loading and phase loss.
• 100 A rating — well-suited for mid-range feeders, pumps, conveyors, and other equipment that draw substantial current.
• 600 V maximum voltage — appropriate for commercial and industrial power systems with higher voltage distributions, while staying within safe operating limits for most related equipment.
• HGA-series compatibility — designed to fit Square D panels and enclosures that accept HGA breakers, enabling straightforward installation and replacement with minimal panel disruption.
• Durable construction and reliable trip response — built to endure demanding environments and provide consistent protection when faults occur.

Ideal use cases:

• Protect 3-phase motor circuits in manufacturing facilities, HVAC equipment, and processing lines.
• Serve as main feeder protection in commercial electrical panels to quickly isolate faults and protect wiring.
• Replacement part for existing Square D HGA installations, preserving panel compatibility and wiring layouts.

Why choose this 3-pole, 100 A, 600 V unit over smaller configurations? The three-pole design ensures cohesive protection across all phases, reducing the risk of damage from partial faults. The 600 V rating adds flexibility for diverse distribution setups, making it a solid, long-term component for reliable power protection in busy environments.

Practical notes for procurement and installation:

• Verify panel labeling to confirm compatibility with HGA-type breakers before replacement.
• Match wiring gauge and conductor sizing to the 100 A feeder specification and follow manufacturer installation guidelines for secure terminations.
• Keep a spare HGA36100SVYP on hand to minimize downtime in critical systems and ensure fast restoration after trips.
