Square D HDA36020AABCSHYP 36020A 3-Pole 600 V Circuit Breaker Potential Transformer

Meet the Square D HDA36020AABCSHYP 36020A, a purpose-built, three-pole circuit breaker with an integrated potential transformer. Designed for demanding industrial power distributions, this unit delivers both protective switching and precise voltage sensing in a single, compact package, rated for up to 600 V across three phases.

Why this integrated solution stands out

• Three-pole protection provides balanced, coordinated tripping across all phases, improving protection accuracy and reducing the risk of undetected faults in 3‑phase systems.
• 600 V rating makes it suitable for industrial equipment, panel boards, and heavy-duty electrical installations common in manufacturing, data centers, and facilities with demanding power needs.
• Built-in potential transformer delivers direct voltage sensing for metering and monitoring, enabling real-time visibility into electrical performance without the complexity of separate transformers.
• Compact, integrated design saves panel space and simplifies wiring, speeding up installation and reducing potential wiring errors during assembly or upgrades.
• Part number specificity HDA36020AABCSHYP ensures precise compatibility with Square D distributions and legacy systems, easing replacement and retrofit projects.
• Durable construction for industrial environments engineered to withstand the temperature and load variations typical in commercial and industrial facilities, helping to improve uptime and safety.

Ideal applications and use cases

This device is well-suited for projects requiring reliable three-phase protection with embedded metering capabilities. Use it in:

• Manufacturing floors and processing plants where continuous monitoring of voltage helps protect equipment and optimize maintenance schedules.
• Data centers and server rooms needing precise voltage feedback to support power usage effectiveness (PUE) goals and energy management systems.
• Large HVAC, pumping, and utility feeders where compact installations reduce panel depth and simplify electrical schematics.
• Upgrades and retrofits of existing Square D panels where a single unit can replace separate protection and metering components, simplifying sparking-free retrofits.

What problems does it solve?

By combining protection and voltage sensing in one device, it minimizes wiring complexity, reduces installation time, and lowers the chance of mis-wired or mislabeled connections. The integrated potential transformer provides immediate voltage feedback to relays and monitoring systems, enabling faster diagnostics, better fault isolation, and improved overall power quality management.

Practical guidance for use

For best results, verify panel compatibility with the HDA36020AABCSHYP, confirm correct mounting in a suitable enclosure, and ensure labeling aligns metering data with your protection schemes. This unit is ideal for professionals seeking a reliable, space-efficient solution that delivers both robust circuit protection and actionable voltage information in a single component.
