Square D | KAL26100 | Circuit Breaker | 100A | 2-Pole | 600V

Introducing the Square D KAL26100 Circuit Breaker — a robust, two-pole, 100-amp device engineered for reliable overcurrent protection up to 600 volts. Designed for maintenance, retrofit, and replacement tasks, this model is your go-to choice when exact compatibility with existing Square D panels is essential.

Built for professional electrical distributions, the KAL26100 ensures you’re pairing the right breaker with the right panel. Use it for upgrading older systems, replacing a failed unit, or retrofitting a panel to handle evolving load demands. Its 2-pole design provides coordinated protection for multi-wire circuits, helping safeguard both conductors and connected equipment while simplifying wiring and testing during installation.

Key specifications

• Amperage: 100 A
• Pole configuration: 2-Pole
• Maximum system voltage: 600 V
• Part reference: KAL26100 (Square D)

Why this model stands out

Choosing the KAL26100 means aligning with Square D’s mounting style, trip characteristics, and labeling conventions. When you replace a breaker with the same part number, you preserve panel integrity, maintain listing compatibility, and minimize downtime. This specificity reduces guesswork during installation and helps ensure safe, predictable performance in demanding electrical environments.

Ideal use cases

• Maintenance of existing Square D enclosures requiring a direct part match
• Retrofits in commercial or light industrial settings where higher protection is needed without changing panel hardware
• Replacement of a 100 A, 2-pole breaker in circuits rated for up to 600 V

Important note: Confirm fit and ratings before ordering. The part number is your best reference for compatibility—compare KAL26100 directly with your panel labeling and the manufacturer’s guidelines to avoid mismatches.
