Square D HDA36070SLYP 70A 3-Pole 600 V Circuit Breaker Potential Transformer

Meet the Square D HDA36070SLYP, a robust three-pole circuit breaker engineered for demanding electrical systems. With a 70 A current rating and a 600 V maximum, this part (HDA36070SLYP) is designed to protect three‑phase feeders and motor circuits in commercial and industrial environments while delivering dependable fault interruption when it matters most.

• Three-pole protection delivers coordinated protection across all phases in a single, compact device, simplifying panel layouts and ensuring balanced trip behavior.
• 70 A continuous current rating provides reliable protection for mid‑size motors, feeders, and distribution circuits without nuisance trips, helping keep downtime to a minimum.
• 600 V voltage rating makes it suitable for higher‑voltage distribution schemes often found in industrial facilities and large commercial installations.
• Square D compatible design ensures a proper fit and predictable performance within Square D panels and enclosures, supporting seamless system integration.
• Potential transformer compatibility supports protection and metering schemes that rely on potential transformer-based monitoring, enabling precise data for relay coordination and fault isolation.

This unit is ideal for applications that demand reliable, coordinated three‑phase protection and easy integration with monitoring systems. It’s a practical choice for panel retrofits or new installations where space is at a premium and consistency with existing Square D components is key.

• three‑phase motor drives, distribution feeders in commercial facilities, or any installation requiring focused protection on all three phases while enabling metering/relay coordination.
• electrical contractors, facility managers, and maintenance teams seeking a proven, compatible protection solution within Square D ecosystems.
• Why it matters: a single, 3‑pole device reduces wiring complexity, improves reliability, and aligns with protection schemes that rely on potential transformer monitoring for faster fault detection.
