Square D HGA36090AABC 36090A 3-Pole 600 V Circuit Breaker

The Square D HGA36090AABC is a purpose-built 3-pole, 600 V circuit breaker that delivers dependable overcurrent protection for three-phase electrical systems. With the precise part number HGA36090AABC, this unit is designed to install in compatible Square D enclosures and panels, providing a reliable safeguard for your industrial or commercial electrical distribution.

Why this 3-Pole 600 V breaker stands out

• Three-pole design enables coordinated disconnection across all three phases, reducing the risk of stray currents and ensuring safer shutdown of three-phase equipment.
• 600 V maximum voltage rating supports a wide range of industrial and commercial applications, from motor feeders to power distribution circuits.
• Part Number accuracy (HGA36090AABC) ensures you’re selecting the exact model needed for replacement, stocking, or system upgrades.
• Built for durability in demanding environments, offering reliable protection for critical equipment and reducing the potential for unplanned downtime.

Ideal use cases

Designed for facilities with three-phase loads, this breaker is well-suited for:

• Industrial motor circuits in manufacturing plants, conveyors, and fans
• Three-phase feeders feeding distribution panels in warehouses and data centers
• HVAC equipment and large mechanical systems that require synchronized tripping across all phases

How it protects your system

By interrupting overcurrents on all three conductors simultaneously, this 3-pole breaker minimizes fault energy and helps protect motors, transformers, and other three-phase equipment from damage due to overloads or short circuits. Its 600 V rating aligns with common industrial standards, supporting safer operation and easier coordination with other protective devices in the same distribution network.

Installation and compatibility considerations

When replacing or stocking this unit, verify that your panel or enclosure is designed to accept the HGA series breakers and that the electrical rating aligns with system requirements. Follow your local electrical codes and the panel manufacturer’s installation guidelines to ensure proper torque, secure mounting, and correct labeling. For best results, plan your protection scheme around a clear understanding of three-phase load profiles and startup currents.

Why choose Square D for overcurrent protection

Square D has a long-standing reputation for reliable, easy-to-integrate protective devices. The HGA36090AABC embodies that heritage with straightforward replacement, predictable performance, and compatibility within standard Square D distribution ecosystems, helping you minimize downtime and maintain safe, compliant electrical operations.
