Why this 3‑pole 600 V circuit breaker stands out

Three-pole design ensures synchronized interruption of all phases, protecting conductors and equipment from imbalances and fault currents. Built by Square D, it brings the trusted reliability of a long-standing electrical protection brand to your panels, helping prevent outages and equipment damage.

• Balanced protection for 3‑phase systems: Tripping all conductors together reduces phase-to-phase fault risks.
• Fast fault interruption: Efficiently handles short-circuit events to minimize component damage.
• Durable construction: Engineered for field use in demanding industrial or commercial environments.

Ideal use cases

• 3‑phase motor circuits in manufacturing lines and HVAC equipment in commercial buildings.
• Feeder protection for electrical panels and distribution boards in retrofit or new installations.
• Any application requiring reliable protection across all three phases at up to 600 V.

Installation and compatibility note: Ensure this breaker is installed in a compatible Square D enclosure or panel that supports HDL-series devices, and verify the amperage rating and trip characteristics align with your circuit design. For best results, consult your electrical diagrams and follow local electrical codes when integrating the HDL36020AABCSK into your protection scheme.
