Eaton | HJD3100W | Circuit Breaker | 100A | 3-Pole

Meet dependable protection with the Eaton HJD3100W circuit breaker—a precise, 100A, 3-pole solution built for demanding electrical systems. Designed for maintenance, retrofit, and replacement tasks, this breaker delivers the exact specifications needed to keep your three-phase setup safe and reliable.

Key Details

• Amperage: 100A
• Poles: 3-Pole
• Part number: HJD3100W
• Important note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Why this Eaton HJD3100W Stands Out

This circuit breaker is purpose-built for three-phase electrical environments where synchronized interruption across all poles is essential. By matching Eaton’s precise HJD3100W specifications, you minimize downtime and ensure consistent protection for downstream equipment, feeders, and motor circuits. The three-pole design is ideal for panel boards and applications that require simultaneous disconnection across three conductors, delivering a safer, more controlled shutdown during fault conditions.

Ideal Use Cases

• Maintenance: Replace aging or worn breakers in compatible Eaton panels to restore reliable protection with minimal system disruption.
• retrofit: Upgrade or modernize existing three-phase circuits where a 100A, 3-pole solution is required to meet current protection standards.
• Replacement: Swap in the exact part reference (HJD3100W) to ensure seamless compatibility and circuit protection without panel modifications.

Fit, Compatibility, and Installation Tips

Before ordering, verify that your panel and bus configuration align with the 3-pole, 100A specifications of the HJD3100W. Always use the exact part number as the compatibility reference to avoid mismatches and ensure proper trip characteristics and secure mounting. If you’re replacing an existing Eaton breaker or performing a retrofit, cross-check the panel’s compatibility guide and service documentation to confirm that HJD3100W is the correct fit for your model.
