Square D HJA260701 70A 2-Pole 600 V Circuit Breaker

Square D HJA260701 70A 2-Pole 600 V Circuit Breaker is a reliable protection solution designed to safeguard electrical circuits in commercial and light industrial environments. With a 70 ampere rating and a two-pole configuration, it provides simultaneous disconnect for both conductors, helping prevent dangerous overloads and keeping systems safer and more dependable.

• Part Number: HJA260701
• Current rating: 70 A
• Poles: 2
• Voltage rating: 600 V
• Brand: Square D

Why this two-pole design matters: When used on multiwire circuits, the breaker ensures both hot legs trip together, reducing the risk of backfed faults and simplifying safety interlock in panels. The 600 V rating makes it suitable for higher voltage distribution, while the 70 A rating protects feeders and motor circuits from overload without nuisance trips in normal operation.

• Feeders to motor starters and industrial equipment in panels rated for 600 V
• Main or branch circuit protection in commercial electrical enclosures
• Upgrading existing Square D panels to a compatible two-pole 70 A breaker

Installation and compatibility: Ensure your panel accepts HJA260701 two-pole breakers and follow local electrical codes for proper mounting and wiring. This part is designed to fit standard Square D enclosures that accommodate 2-pole devices of this type.

Maintenance and care: Regularly inspect for signs of wear, overheating, or frequent tripping. Replace the breaker if you notice damage or degraded performance to maintain reliable, safe operation of your electrical system.
