Square D HDA261502AABCSK 261502A 2-Pole 600 V Circuit Breaker

Experience precise overcurrent protection with the Square D HDA261502AABCSK 2-Pole 600 V Circuit Breaker. This part, identified by HDA261502AABCSK and commonly referenced as 261502A, is built to safeguard 600-volt electrical circuits by interrupting fault currents quickly and reliably. Designed for panel compatibility within the Square D ecosystem, it delivers consistent performance across installation environments.

Key specifications

• Poles: 2
• Voltage rating: 600 V
• Part number: HDA261502AABCSK
• Model reference: 261502A

What this two-pole breaker does for you

With a two-pole design, both hot conductors in a 600 V circuit are disconnected simultaneously, reducing arc flash risk and ensuring clear isolation of the fault. This makes it especially suitable for equipment and circuits where simultaneous disconnection enhances safety and protects both people and equipment.

Ideal use cases

• Commercial and light-industrial panels that operate up to 600 V and require reliable two-pole protection
• Motor control circuits, transformers, and branch circuits fed from 600 V distribution networks
• Panel upgrades or replacements within Square D installations to maintain consistent protection characteristics

Why choose Square D HDA261502AABCSK

As part of the Square D protection lineup, this HDA-series breaker is engineered for compatibility with Square D panels and distribution equipment. By matching the HDA family’s trip curves and mounting interfaces, you gain predictable performance, easier panel planning, and fewer mismatches when refreshing protection devices in a 600 V system.

Practical tips

• Verify that your panel is designed to accept HDA-series breakers and that the voltage rating matches your circuit requirements (600 V)
• Keep a spare HDA261502AABCSK on hand for quick replacements and minimized downtime in critical electrical rooms
• Inspect periodically for signs of wear, overheating, or physical damage after fault events and replace promptly if any concern arises
