What sets the CC3100YJ apart

• Integrated potential transformer for sensing: Connects directly to metering and monitoring systems, delivering accurate current information without the need for separate sensing components.
• Compact, integrated protection and measurement: Combines protection functions and current sensing in one device, reducing wiring complexity and simplifying panel layouts.
• Designed for 3‑phase 240V systems: Ideal for commercial electrical distributions, data centers, and industrial equipment feeders that rely on precise protection and real-time monitoring.
• Reliability in demanding environments: Built to perform in standard Eaton panel configurations where robust protection and seamless integration with monitoring infrastructure are priorities.

Ideal use scenarios

• New or retrofit installations in commercial buildings needing streamlined protection and metering in one unit.
• Data centers and server rooms where real-time current sensing supports energy management and fault detection.
• Manufacturing floors with three‑phase feeders requiring reliable protection alongside integrated measurement for process monitoring.
• Electrical panels and switchgear that benefit from reduced wiring and simplified maintenance through an integrated sensing solution.

How it works

The CC3100YJ leverages an integrated potential transformer to provide a low‑voltage sensing signal derived from the three‑phase current. This enables compatible metering and monitoring equipment to track load conditions, detect abnormal currents, and support protective relays—without needing separate current transformers. In short, you get accurate protection alongside meaningful, real‑time electrical data in a single device.

Installation, compatibility, and maintenance

• Ensure your panel supports 3‑pole, 240V protection devices and is compatible with Eaton CC-series configurations.
• Verify correct wiring for the 100A feeders and connect the integrated sensing output to your metering or monitoring system according to the installed equipment’s guidance.
• Use a licensed electrician for installation to ensure proper torque on connections and compliance with local electrical codes.
• Periodically inspect connections for tightness and inspect sensing leads for any signs of wear or damage; replace components if insulation or conductors show deterioration.

Why choose Eaton CC3100YJ

• Single‑unit solution that merges protection and current sensing for streamlined panel design.
• Reliable 100 A, 3‑phase protection at 240 V, supporting common commercial and industrial power distributions.
