Square D HDA36080SR 80A 3-Pole 600 V Circuit Breaker

Square D HDA36080SR 80A 3-Pole 600 V Circuit Breaker is a purpose-built safety device engineered to protect your three-phase electrical distribution from overloads and short circuits. With an 80-amp rating and a 3-pole configuration, this breaker interrupts fault currents across all three phases, helping safeguard motors, drives, and other heavy equipment in industrial and commercial settings.

Part Number HDA36080SR specifies a direct-fit solution for Square D panels that accept HDA-series breakers. Rated for up to 600 V, it is ideal for higher-power distribution systems found in manufacturing facilities, large HVAC installations, and data centers. This is a professional-grade circuit breaker designed to deliver reliable fault interruption when it matters most.

• Three-phase protection for equipment such as motors, conveyors, pumps, and industrial controls in 600 V systems.
• 80 A rating provides precise overload protection while allowing normal operating current to flow through the feeder.
• 3-pole design ensures simultaneous disconnection of all phases, reducing residual voltage and protecting connected devices.
• Direct compatibility with Square D panels that support HDA-series breakers, simplifying replacement and maintenance.
• Clear part identification (HDA36080SR) supports efficient stocking, service, and warranty processes in professional facilities.

Practical installation notes: Confirm that your panel accepts HDA-series devices and follow local electrical codes for wiring and torque specifications. For ongoing reliability, replace aging breakers before nuisance trips occur, and keep an on-hand stock of HDA36080SR units to minimize downtime during maintenance.
