What makes this breaker stand out

The KAL3625026M is built for feed-through applications, enabling streamlined downstream protection without extra adapters or complex wiring. Its three-pole design provides balanced protection for three-phase systems, helping to maintain system stability and reduce nuisance trips in commercial and industrial environments. With a 25kA interrupting capacity, it’s equipped to handle short-circuit events with confidence, protecting both equipment and personnel.

Who benefits most

• Electrical contractors performing retrofits or replacements in existing Square D panels that support feed-through configurations.
• Facilities engineers upgrading service feeders in warehouses, manufacturing floors, data centers, and large office complexes.
• Maintenance teams that need exact, compatible replacements to minimize downtime and ensure consistent protection.

Why choose this model for your project

Choosing the KAL3625026M means aligning with a trusted protection solution from Square D. The 600 V rating and 25 kA interrupting capacity provide a balance of protection and performance for medium- to high-energy systems. The feed-through design reduces installation complexity by enabling direct downstream connections, which can simplify panel layout and improve reliability during maintenance.

Practical installation and compatibility notes

Before ordering, confirm the fit and ratings match your panel and application. The part number KAL3625026M is the best reference for compatibility—use it to verify form factor, mounting, and downstream connection requirements with your existing Square D gear.

Examples of use cases include retrofitting legacy panels to accommodate higher protection budgets, replacing aging feeders in multi-panels, or upgrading system protection while maintaining a clean, consistent electrical architecture.
