Square D HDA36070UAYP 70A 3-Pole 600 V Circuit Breaker Potential Transformer

Meet the Square D HDA36070UAYP, a rugged, metering-ready circuit breaker engineered for demanding three‑phase power environments. With a 70 A current rating, a 3‑pole configuration, and a 600 V maximum rating, this device provides reliable protection for critical equipment while offering integrated potential transformer functionality for streamlined monitoring and control.

Why this breaker stands out

• 70 A current rating delivers precise overcurrent protection for mid‑sized motor circuits and industrial loads.
• 3‑pole design ensures balanced protection across all three phases in a typical 3‑phase system, supporting coordinated trip and fault isolation.
• 600 V voltage rating suitable for industrial distribution and higher‑energy applications common in manufacturing and facilities management.
• Integrated potential transformer enables direct sensing and metering from the breaker, simplifying energy management, protective relays, and SCADA/BMS integration without excessive external wiring.
• Part number HDA36070UAYP provides exact replacement compatibility within the Square D and Schneider Electric ecosystem, reducing installation risk and downtime.

Ideal use cases

• Three‑phase motor branches (pumps, fans, conveyors) where reliable protection and easy access to power quality data are priorities.
• Electrical panels and switchgear layouts where space is at a premium and a combined protection‑and‑metering solution saves wiring and panel real estate.
• Industrial facilities and data‑driven environments that rely on precise energy measurement for maintenance planning, efficiency tracking, and fault diagnosis.

What matters to you, and how this helps

• Direct metering capability reduces the need for separate CT/PT wiring runs, speeding up commissioning and enabling more accurate energy reporting for budgets and optimization initiatives.
• Robust, reliable protection guards critical loads against overloads and faults, supporting longer equipment life and less unplanned downtime.
• Easy replacement and compatibility using the exact HDA36070UAYP part number minimizes compatibility surprises during upgrades or service, helping you maintain consistent performance across panels.
