Square D HDA260402AABCSD 260402A 2-Pole 600 V Circuit Breaker

Square D HDA260402AABCSD is a rugged 2-pole, 600 V circuit breaker designed to protect electrical distribution systems from overloads and short circuits. This specific model, identified by part number HDA260402AABCSD (often referenced as 260402A), is built to reliably interrupt fault current and safeguard connected equipment in demanding environments.

• Configuration: 2-pole protection to simultaneously disconnect both hot conductors
• Voltage rating: 600 V
• Part/Model: HDA260402AABCSD (alias 260402A)

Why this two-pole design matters: when a fault occurs, disconnecting both lines at once minimizes shock risk during maintenance and helps ensure comprehensive protection for downstream devices such as feeders, motors, and circuit wiring in industrial and commercial panels.

Ideal use scenarios include electrical panels in manufacturing facilities, processing plants, and other settings where reliable, straightforward overcurrent protection is essential. The HDA260402AABCSD is suited for installations that require a sturdy, dependable protection device in a compact footprint, capable of quickly responding to overcurrent conditions to prevent damage and downtime.

Key benefits and practical considerations:

• Delivers consistent overcurrent protection for two conductors, helping to safeguard circuits and equipment from damaging faults
• Activated as a straightforward protection option in Square D-compatible panels designed for HDA-series breakers
• Simple identification via the distinctive part number (HDA260402AABCSD) and model lineage (260402A) for easy ordering and replacement
• Suitable for applications where a 2-pole, 600 V protection device is required to meet system design and safety standards

Usage guidance (practical tips): verify that your panel or enclosure supports HDA-series breakers, confirm the voltage and pole configuration matches your circuit requirements, and keep the part number handy for ordering replacement or spare units. This model is a purpose-built solution for engineers and electricians seeking dependable, two-pole protection with a clear, straightforward fit into compatible Square D installations.
