Square D | KA36250 | Circuit Breaker | 3-Pole

Square D KA36250 is a reliable 3-pole circuit breaker designed for three-phase protection in commercial and industrial electrical systems. Built for maintenance, retrofit, and replacement projects, this KA36250 unit helps keep your Square D panels secure and operational by providing a precise, compatible solution when you need to refresh or expand your protection scheme.

Why this 3-Pole breaker matters

• Three-phase protection—the 3-Pole design guards three conductors simultaneously, essential for balanced motor loads, data center gear, and other three-phase equipment.
• Exact compatibility reference—the part number KA36250 is the primary reference for identifying a proper fit within Square D systems. Use it to confirm you’re selecting the correct replacement or retrofit part.
• Fit and ratings first—before ordering, verify the panel’s model, voltage, and interrupting rating to ensure safe and reliable operation with this breaker.
• Maintenance and retrofit ready—ideal for refurbishing aging panels, expanding three-phase capacity, or restoring protective devices in existing Square D installations.

What you’ll gain with KA36250

• Consistent protection that matches the original system’s trip characteristics, helping minimize downtime and equipment wear.
• Streamlined part matching—using the KA36250 part number as your compatibility reference simplifies ordering and reduces the risk of mismatches.
• Practical reliability from a trusted Square D design, delivering predictable performance in demanding environments.

Ideal use scenarios

• Replacing a failed 3-pole breaker in a three-phase commercial or light-industrial panel.
• Carrying a spare KA36250 for proactive maintenance and faster service calls.
• Retrofits where three-phase protection must be preserved or expanded without changing the panel layout.

Installation and safety notes

Always confirm fit and ratings before purchasing. Check the panel’s model and the breaker’s voltage and interrupting rating to ensure seamless integration with your Square D enclosure. Because this is a Square D part, it’s designed to align with the bus configuration and mounting of compatible panels, helping protect connected equipment and maintain code compliance.
