Meet the Square D HDA36070 70A 3P 600V circuit breaker — a dependable protection device designed for panelboards, load centers, and electrical distribution networks. The three-pole (3P) design delivers robust protection for three-phase circuits, while the 70 A rating provides precise overload protection for mid-sized feeders in commercial or industrial setups. With a 600V operating range, it’s built to handle demanding power distribution environments with confidence.

Designed with retrofit and maintenance in mind, this breaker offers exact part-number compatibility to keep your installations consistent. For projects where you must maintain the original part number, the HDA36070 model ensures seamless substitution without reconfiguring other components in your system.

Why this model stands out

  • Exact-fit for Square D systems — ideal for retrofit or refurbishment projects where continuity of the part number is essential.
  • Three-pole protection — protects three-phase circuits in panelboards and distribution gear, helping prevent costly faults across your system.
  • 700V? Not here — this unit is specified for 600V networks, aligning with common industrial and commercial distribution standards.
  • Availability from AmpState — easy to source when you’re planning replacements or stock management.
  • Support for compatibility checks — if you’re unsure about fit, you can reach out for confirmation to ensure a drop-in replacement.
