Square D KAL26090 - 90A, 2-Pole, Circuit Breaker

Introducing the Square D KAL26090 — a 90A, 2-Pole circuit breaker designed for dependable overcurrent protection in demanding electrical environments. Built for industrial, commercial, and OEM applications, this device keeps distribution panels and motor control centers running smoothly by quickly interrupting fault currents while prioritizing safe operation.

Smart design for flexible protection

• Current rating: 90A
• Poles: 2-Pole
• Breaker type: Circuit Breaker

The 2-Pole configuration provides two interrupting paths in a compact form factor, making it ideal for panelboards, switchboards, and control panels where reliable protection across multiple conductors is required. This is especially valuable in distribution panels and motor control centers where consistent performance minimizes downtime and equipment wear.

Who benefits most

• Industrial facilities needing robust, real-time overcurrent protection
• Commercial service panels requiring dependable protection for feeders and equipment
• OEMs and panel builders compiling reliable, ready-to-install protection into custom assemblies

Why this matters

Beyond a rating, the KAL26090 delivers practical value: a proven Square D design that integrates with common panel systems, supports straightforward maintenance checks, and provides predictable trip behavior to guard motors, transformers, and feeders from overloads and short circuits.

Tips for optimal use

• Use in panelboards, switchboards, and control panels where two hot lines require simultaneous protection
• Ensure compatibility with your existing Square D distribution architecture and mounting footprint
• Follow standard electrical installation practices and manufacturers' guidelines for wiring and termination torque
