Eaton | HKD2100 | Circuit Breaker | 100A | 2-Pole | 600V

Engineered by Eaton, the HKD2100 circuit breaker delivers reliable overcurrent protection for 100A circuits in 2-pole, 600V electrical systems. Ideal for maintenance, retrofit, and replacement projects where exact specifications matter, this breaker is designed to plug into Eaton-compatible panels and configurations with precise fit and performance expectations.

Key specifications

• Amperage: 100A
• Poles: 2-Pole
• Voltage: 600V
• Part number: HKD2100

Why the HKD2100 matters

The HKD2100 is the definitive reference for matching Eaton protection hardware. By prioritizing the part number as your compatibility guide, you ensure the right mounting, electrical characteristics, and interface with your panel or system. This makes it especially valuable for service technicians and facilities teams planning long-term maintenance or multi-location retrofits where consistent components simplify stocking and training.

Ideal use cases

• Maintenance: keep spare breakers on hand so routine service doesn’t disrupt operations.
• Retrofit: upgrade legacy installations that require a 2-pole, 600V configuration with a reliable 100A protective device.
• Replacement: swap in a like-for-like unit when an existing HKD2100 or compatible Eaton breaker reaches end of life.

Compatibility and verification

1. Check the existing panel or distribution equipment labeling to confirm it supports a 100A, 2-pole, 600V breaker in the Eaton family.
2. Use the part number HKD2100 as the primary reference to ensure the replacement matches the original device’s specifications.
3. Confirm fit and ratings before ordering to avoid mismatches in mounting, bus connection, or protective characteristics.

Installation and safety notes

• Always power down the main disconnect and follow lockout/tagout procedures before working on any panel.
• Install only by qualified personnel in accordance with local electrical codes and manufacturer guidelines.
• Handle the device carefully to preserve its protective properties and ensure secure mounting in the intended panel.

Practical tips for procurement and use

• Keep the HKD2100 as part of a reliable spare parts kit for fast field replacements and reduced downtime.
• Document purchase date and panel compatibility to streamline future maintenance planning.
• When in doubt, cross-check the panel’s labeling and the Eaton part catalog to confirm that HKD2100 aligns with the required trip characteristics and mounting style.
