Product description
Shipping
The Eaton KD4100W circuit breaker delivers reliable, high-velocity protection for demanding electrical systems. With a 100A rating and a four-pole configuration, it’s built to safely disconnect all active conductors in multi‑phase environments while handling up to 600V. Designed for maintenance, retrofit, and replacement projects, this is a purpose-built solution when exact specifications matter.
Key specifications
- Amperage: 100 A
- Poles: 4-Pole
- Voltage: 600 V
- Part number: KD4100W
Why this matters for your panel
- Exact compatibility: Using the KD4100W ensures your panel wiring and protection schemes align with the original design, reducing compatibility risks during retrofits or replacements.
- Comprehensive protection for multi‑conductor systems: The four-pole design enables simultaneous disconnection of all conductors in a multi-phase setup, enhancing safety and fault handling in 3‑phase installations with a neutral.
- Reliability you can trust: As an Eaton component, it anchors your electrical protection strategy with a part that’s engineered for consistent performance in demanding environments.
Ideal use cases
- Maintenance replacements in existing Eaton panels that require a 100 A, 4‑pole, 600 V breaker
- Retrofits where system specifications match KD4100W, ensuring continued protection without panel redesign
- New installations in 3‑phase systems that call for a four‑conductor disconnect at 600 V
Installation and compatibility notes
Before ordering, verify fit and ratings to avoid mismatches. The KD4100W part number is your best reference for compatibility with compatible Eaton panels and accessories. Follow the panel manufacturer’s installation guidelines, and ensure that wiring and torque practices align with local electrical codes for safe, durable operation.
What problems this solves
- Prevents overcurrent damage by delivering a precise 100 A protective threshold tailored to your system’s load profile
- Minimizes downtime by matching the exact part reference needed for straightforward replacement, reducing trial-and-error ordering
- Supports safe shutdown of all conductors in multi‑phase circuits, helping to protect both equipment and personnel during maintenance
