• Amperage: 125 A
• Poles: 2-Pole
• Voltage rating: 600V
• Configuration: Feed-Through lugs for efficient downstream wiring
• Part reference: KAL26125 — use this number to verify compatibility with your panel or enclosure

Why this Square D circuit breaker stands out

Designed for real-world installations, the KAL26125 combines robust electrical protection with practical wiring advantages. The feed-through feature lets you carry power forward to downstream circuits without needing extra adapters or custom harnesses, reducing installation time and clutter in crowded panels. Its 125-amp rating is a precise fit for medium-to-large feeder applications, providing dependable protection without unnecessary tripping for correctly sized loads.

Better fits for maintenance, retrofit, and replacement

Whether you’re upgrading aging equipment, matching a retrofit plan, or stocking spare parts for routine maintenance, this unit is a straightforward match when your system calls for: two hot legs, a 600V maximum, and a feed-through configuration. The part number KAL26125 is your best reference for compatibility, so keep it on hand when ordering or cross-checking with existing panels.

Ideal use scenarios

• Retrofits where downstream wiring must stay tidy and accessible — the feed-through design minimizes additional connections.
• Replacement of failed or outdated 2-pole breakers in 600V circuits within industrial or commercial wiring schemes.
• Maintenance inventories for facilities that rely on rapid, reliable protection during power distribution upgrades.
• New installations requiring a compact, two-pole 600V protective device with built-in feed-through capability.

Practical installation and safety notes

Before ordering or installing, confirm that the panel or enclosure requires a 2-pole 125A, 600V feeder with feed-through lugs. Always follow proper lockout/tagout procedures and consult your panel’s documentation to verify fit and ratings align with the KAL26125. Using the correct part number helps ensure you’re selecting a device that matches the panel’s physical dimensions, electrical characteristics, and downstream wiring requirements.

What you gain with this model

• Reliable overcurrent protection for 125A feeder circuits in systems up to 600V, reducing the risk of damage from faults.
• Streamlined wiring thanks to integrated feed-through lugs, cutting installation time and simplifying downstream connections.
• Clear traceability and compatibility through the dedicated KAL26125 part reference, supporting precise sourcing and replacement planning.
• Versatility for maintenance, retrofit, and replacement projects — a practical choice for facilities that prioritize uptime and serviceability.

Choose the Square D KAL26125 when you need a dependable, install-friendly 2-pole, 125A circuit breaker with feed-through capability for 600V systems. Its combination of robust protection, wiring convenience, and clear compatibility reference helps ensure efficient workfl ows and long-term reliability in your electrical distribution network.
