Schneider Electric | CK1200NA | Circuit Breaker | 1200A | 3-Pole | 600V

Schneider Electric CK1200NA is a high-capacity circuit breaker designed for demanding 600V electrical systems. With a 1200A rating and a 3-pole configuration, this unit delivers reliable three-phase protection for industrial and commercial panels. It’s especially suited for maintenance, retrofit, and replacement projects where exact compatibility matters, helping you minimize downtime while keeping safety front and center.

• Amperage: 1200A
• Poles: 3-Pole
• Voltage rating: 600V
• Part reference: CK1200NA — the best reference for compatibility

Why choose the CK1200NA for your electrical distribution

When your system runs on Schneider Electric hardware, staying with the CK1200NA ensures you’re matching the original design intent for protection, timing, and coordination. The CK1200NA is purpose-built to handle high-current scenarios common in industrial environments, delivering predictable performance and simplifying panel maintenance. Rely on Schneider Electric’s engineering heritage to support long-term reliability, consistent trip characteristics, and straightforward integration with compatible enclosures and bus-bar configurations.

Ideal use cases

• Maintenance and spare parts for existing 600V, three-phase installations that originally used CK1200NA
• Retrofit projects where a precise 1200A, 3-pole breaker is required to restore protective coordination
• Repairs or upgrades in industrial facilities, manufacturing lines, or large commercial power distributions needing robust fault interruption

Fit, compatibility, and ordering tips

To ensure a seamless fit, confirm that your panel or distribution board accepts CK1200NA breakers with the same amperage, poles, and voltage rating. The CK1200NA part number is the most reliable reference for compatibility. Before ordering, verify:

1. The panel’s rating and acceptable breaker family match CK1200NA specifications.
2. The form factor and mounting method align with your enclosure’s design and available space.
3. That the current and phase configuration in your distribution aligns with a three-pole, 600V breaker.

Handling, installation, and safety considerations

• Power must be isolated and verified off before any replacement or maintenance work.
• Follow lockout/tagout procedures and wear appropriate PPE during installation or servicing.
• Store and handle the CK1200NA in a clean, dry environment to preserve performance and reliability.
