Square D HDA36070UJYP 70A 3-Pole 600 V Circuit Breaker

The Square D HDA36070UJYP 70A 3-Pole 600 V Circuit Breaker is built to protect your three-phase electrical distribution with precision and reliability. Designed for commercial and light-industrial panels, this unit provides robust protection for critical loads while simplifying panel management in demanding environments.

• Current rating: 70 A helps safeguard motor loads, pumps, and other equipment without nuisance trips from normal startup surges.
• Pole configuration: 3-pole design ensures all three phases trip together, reducing the risk of unbalanced faults and equipment damage.
• Voltage rating: rated up to 600 V, suitable for higher-voltage distribution networks and industrial applications.
• Part number: HDA36070UJYP, making ordering and cross-referencing straightforward within the Square D ecosystem.
• Brand compatibility: aligns with Square D panels and bus systems, promoting seamless installation and dependable serviceability.
• Application-ready for 3-phase protection: ideal for safeguarding feeders that power motors, compressors, HVAC equipment, and other three-phase machinery in offices, warehouses, and manufacturing spaces.

Why this model stands out: it combines a precise 70 A rating with a 3-pole configuration and a 600 V rating in a single, reliable device. Compared with using multiple single-pole breakers for a 3-phase circuit, this breaker simplifies wiring, supports a true trip across all phases, and helps maintain a safer, more predictable shutdown during faults. It’s a practical choice for facilities managers, electrical contractors, and maintenance teams seeking dependable protection for essential equipment.

Practical guidance: ensure you’re pairing this breaker with compatible Square D panels and follow your panel’s installation and torque specifications for secure lugs and connections. Use it to protect distribution feeders, motor circuits, and other critical loads where reliable 3-phase interruption up to 600 V is required.
