Square D HGA36100SN 100A 3-Pole 600 V Circuit Breaker

Square D HGA36100SN 100A 3-Pole 600 V Circuit Breaker delivers rugged, dependable protection for three-phase power distribution. Built to interrupt all live conductors quickly, this breaker helps safeguard motors, equipment, and personnel in demanding industrial and commercial environments.

• Three-pole design for true 3-phase protection: When a fault occurs, all three lines trip together, reducing the risk of phase-to-phase faults and ensuring consistent shutdown of 3-phase circuits.
• 100 A rating: Precisely sized to protect motors, pumps, conveyors, and other 3-phase loads up to 100 A without nuisance trips when operated within its rating.
• 600 V maximum system voltage: Suitable for industrial power distribution that requires reliable protection in relatively high-voltage applications.
• Part number clarity: HGA36100SN identifies this exact unit within Square D’s HGA family, supporting straightforward ordering and replacement in compatible panels and enclosures.
• Rugged, panel-ready construction: Designed for use in commercial and industrial panels that support Square D breakers, delivering consistent performance in demanding environments.

Ideal applications

• Three-phase motor circuits in manufacturing lines, CNC machines, and processing equipment.
• Three-phase feeders and sub-feed disconnects in industrial distribution panels.
• HVAC and cooling systems that run on 3-phase power, where reliable overcurrent protection is essential.
