Square D KAL26200 - 200A, 2-Pole, Waterproof DC Circuit Breaker

Square D KAL26200 is a rugged 200A, 2-Pole, waterproof DC circuit breaker designed for the most demanding DC distribution environments. Built to interrupt fault currents safely in outdoor, wet, or harsh industrial spaces, this unit delivers dependable overcurrent protection where it matters most.

Key features

• 200A current rating for high-demand DC circuits in panelboards, switchboards, and motor control centers
• 2-Pole design ensures simultaneous disconnection of both conductors, improving safety and preventing single-conductor faults in DC systems
• Waterproof enclosure engineered to withstand exposure to moisture, rain, and washdown environments
• Dedicated DC breaker type optimized for DC current interruption and reliable performance in industrial and OEM equipment
• Versatile installation suitable for distribution panels and control panels in industrial and commercial facilities

Why this matters for your operation

In DC systems—such as battery banks, solar DC buses, and DC-controlled equipment—rapid, reliable fault interruption is critical. The Square D KAL26200 provides robust protection against short circuits and overcurrents, reducing equipment wear, downtime, and safety risks in harsh environments.

Ideal use cases

• Outdoor or damp environments in panelboards, switchboards, and MCCs
• Industrial automation setups with centralized DC distribution
• OEM equipment enclosures that require rugged, waterproof protection
• Solar/energy storage installations where dependable DC protection is essential

Installation tips and considerations

• Match the 200A rating to your conductor sizing and load requirements to ensure proper protection without nuisance trips
• Use in enclosures designed for waterproof DC devices and follow manufacturer torque specifications for terminations
• Plan for maintenance checks of seals and mounting hardware to preserve waterproof performance over time
• Confirm compatibility with your panelboard or MCC’s mounting footprint and wiring methods

How it compares to standard DC protection

DC circuits pose different arc behavior than AC. This unit is purpose-built as a waterproof DC circuit breaker, providing appropriate interrupt capabilities and environmental sealing for reliable performance in wet, industrial settings—more suited to DC distribution than generic AC-only breakers.

Equip your DC distribution with the Square D KAL26200 for dependable, field-proven overcurrent protection that stands up to moisture and tough industrial conditions.
