Square D HDA260501AABCSDYP 260501A 2-Pole 600 V Circuit Breaker

Meet the Square D 2-Pole 600 V Circuit Breaker, model HDA260501AABCSDYP. Built for robustness in demanding electrical environments, this device delivers reliable dual-line protection for panels and distribution systems that run up to 600 volts. With the part number HDA260501AABCSDYP and family designation 260501A, it’s designed for straightforward ordering and effortless replacement in existing Square D installations.

Precise dual-line protection for safer, simpler panel wiring

The two-pole configuration ensures both conductors trip together, preventing mismatched disconnections and reducing arc-flash risk during faults. With a 600 V rating, this breaker is suited for mid- to high-voltage applications, including feeder circuits, motor controls, and commercial electrical installations where coordinated protection is essential.

• Two-pole design ensures simultaneous disconnection of both lines for safer fault clearance.
• 600 V voltage rating aligns with common 600 V electrical infrastructure in commercial and light industrial settings.
• Part number compatibility HDA260501AABCSDYP and 260501A family for easy identification and cross-reference.
• Compact Square D form factor designed to fit standard panel enclosures and bus layouts compatible with Square D systems.

Ideal use cases

This breaker is a solid fit for environments where dual-pole protection is required or preferred. Consider it for:

• Feeder circuits in 600 V panel boards, ensuring reliable protection for upstream equipment.
• Motor control circuits and HVAC feeders where simultaneous line disconnection enhances safety and simplicity.
• Repairs and replacements in existing Square D installations that reference the HDA260501AABCSDYP model.

Why this Square D breaker stands out

Instead of handling single-pole protection in isolation, the HDA260501AABCSDYP provides coordinated trip across two poles, streamlining wiring layouts and improving on-system safety. Rooted in Square D’s legacy of dependable electrical protection, this model offers predictable performance and reliable operation across its service life.
