Square D HDA36030AABCSD 36030A 3-Pole 600 V Circuit Breaker

Introducing the Square D HDA36030AABCSD 36030A 3-Pole 600 V Circuit Breaker—a purpose-built safeguarding device for demanding 3‑phase power systems. With a 3-pole configuration and a 600 V maximum rating, this unit is designed to interrupt fault currents quickly and protect costly equipment from overloads and short circuits.

Key specifications

• Part Number: HDA36030AABCSD
• Current Rating: 36030 A
• Poles: 3
• Voltage Rating: 600 V

Why this matters: three-phase protection requires a breaker that can simultaneously disconnect all live conductors to prevent unbalanced loads and cascading faults. The HDA series from Square D is built to maintain consistent performance across the full load range, giving you predictable isolation when faults occur and reducing the risk of equipment damage.

Ideal use cases:

• Industrial motor circuits and drives where three-phase protection is essential
• Three-phase distribution panels in manufacturing floors, warehouses, and HVAC systems
• Critical services in data centers or commercial facilities that rely on stable 3‑phase power

Practical considerations and benefits:

• Designed for integration with Square D panels and standard mounting footprints, enabling straightforward replacement and upgrade paths.
• Part number clarity (HDA36030AABCSD) simplifies procurement, stocking, and service records.
• Using a dedicated 3-pole 600 V breaker helps ensure coordinated protection across all phases, improving fault handling and safety.

Tips for installation and care:

• Verify the panel is rated for 600 V and supports 3-pole breakers of this form factor before installation.
• Have a qualified electrician perform wiring and torque checks according to the manufacturer’s guidelines and local codes.
• Maintain an inventory of the exact part (HDA36030AABCSD) to simplify future replacements and warranty management.
