Square D HDA260504AABCSH 260504A 2-Pole 600 V Circuit Breaker

Meet the Square D HDA260504AABCSH 260504A 2-Pole 600 V Circuit Breaker — a rugged, dependable overcurrent protection device designed for demanding electrical systems. Built to fit into Square D panels and compatible distribution setups, this two-pole breaker delivers reliable isolation and protection in a compact package. The current rating is specified as 260504 A, with a maximum system voltage of 600 V, making it suitable for mid- to high-voltage applications where two conductors must be switched together for safe shutdown.

Why this 2-Pole, 600 V design matters

• Two-pole protection ensures both live conductors disconnect together, reducing the risk of arc and providing comprehensive circuit protection in enclosures and panelboards.
• 600 V maximum rating supports industrial and commercial distribution scenarios where higher voltages are present, helping protect equipment and wiring from overload and fault conditions.
• Part number clarity HDA260504AABCSH identifies a precise Square D component, simplifying sourcing, maintenance, and replacement in existing installations.

What problems it solves

• Prevents electrical overloads from propagating through feeders and branch circuits by interrupting fault current promptly.
• Provides a clear, reliable point of disconnect for safe maintenance and service work in electrical panels.
• Helps maintain system safety and continuity in environments where multi-pole protection is required for both conductors.

Ideal for

Industrial facilities, commercial buildings, and other setups where 2-pole, 600 V protection is mandatory. This breaker is well-suited for panelboards and distribution systems that rely on precise, dependable overcurrent protection for two live lines.
