Why this GE CDK2400 stands out

Designed for reliability in demanding environments, the CDK2400 combines solid build quality with straightforward integration into GE-compatible panels. Its 2-pole configuration provides synchronized disconnection of both hot conductors, reducing the risk of shock and improving protection for large feeders and equipment rooms. If your electrical system runs at 240 volts and requires substantial interrupting capacity, this breaker offers a robust solution that aligns with GE’s engineering standards and service expectations.

Ideal use scenarios

• Main protection for commercial and light industrial service panels that run on 240 V
• Large feeder protection for equipment rooms, data centers, and manufacturing plants
• Replacement or upgrade in GE CDK-compatible panels where a high-amperage main is required

Installation and compatibility tips

1. Verify panel compatibility with GE CDK-series breakers before installation to ensure a secure fit and proper electrical clearance.
2. Check bus bar and mounting orientation to match the panel’s design—correct alignment ensures reliable trip operation and easy servicing.
3. Label the main protective device clearly in the panel schedule to support code compliance and future maintenance.
4. Consult electrical codes and, if needed, a licensed professional to confirm suitability for your specific service entrance or feeder configuration.

Choosing the GE CDK2400 means equipping your 240-volt system with a purpose-built, high-capacity main protection device that supports safe, uninterrupted operation of large electrical loads. For facilities demanding robust protection at 400 A, this 2-pole breaker offers a precise balance of performance, reliability, and ease of integration within GE-panel ecosystems.
