Square D | KA26150AB | Circuit Breaker | 150A | 2-Pole | 600V | 25kA

Designed for robust protection in 600-volt electrical systems, the Square D KA26150AB Circuit Breaker delivers reliable performance in a compact 2-pole package. With a 150A rating and a 25kA interrupting capacity, it’s built to safeguard sensitive equipment and wiring from short circuits and overloads. Ideal for maintenance, retrofit, and replacement projects, this breaker aligns precisely with the KA26150AB specifications that match your panel’s requirements.

Key specifications

• Amperage: 150A
• Poles: 2-Pole
• Voltage: 600V
• Interrupting capacity: 25kA

The KA26150AB is tailored for installations where a 2-pole, 600V protective device is needed to safely interrupt high fault currents. Its 25kA interrupting rating provides a strong margin against faults, helping to protect downstream equipment and reduce the risk of damage during surge events.

Why this KA26150AB stands out

• The part number KA26150AB is the most reliable reference for determining fit with your panel or enclosure. Confirming the exact match before ordering minimizes the risk of incompatible replacements.
• Maintenance-friendly design: This breaker is suited for routine service and retrofit projects, allowing you to upgrade or restore protection without a full panel replacement.
• Clear, robust protection: With a 150A capacity and 25kA fault interruption, it provides solid defense against overloads and high-energy faults in commercial or industrial settings.

Ideal use cases

• Replacing aging or failed 150A, 2-pole breakers in 600V distribution panels.
• Retrofits to upgrade panel protection in equipment rooms, manufacturing lines, or data centers where 600V systems are standard.
• Maintenance planning for utility rooms or subpanels that require reliable, high-interrupting-capacity devices.

Practical installation notes: verify that your panel enclosure is rated for 600V and 150A, and ensure the bus configuration accepts a KA26150AB 2-pole device. As a best practice, review the panel’s labeling and the equipment spec sheet to confirm full compatibility before purchase and replacement.
