The FDB3100 – EATON 3P100A 600V Molded Case Breaker is designed for robust performance and reliability in electrical systems. This three-pole breaker offers superior protection with a 100A rating, handling up to 600V. Ideal for industrial applications, it ensures safety, eases maintenance, and supports long-term operation of your electrical infrastructure.
The FDB3100 is an Eaton FDB-frame molded-case breaker designed for industrial and commercial panelboards and switchboards — not residential loadcentres. Compatibility depends on your specific board's bus size, bolt-on configuration, and available space. Contact us with your panelboard model number and we'll confirm whether this breaker is the right fit.
Whether 14kAIC is sufficient depends on the available fault current at the point of installation. You'll need a short-circuit study or utility fault-current data for your site. If your application requires a higher interrupting rating, Eaton offers higher-rated frames (such as the HFD or JD series) — we can help you identify the right alternative. Always verify with a qualified electrical engineer.
The Eaton FDB frame series is considered a legacy/obsolete product line in many markets. Northern Breaker Group specialises in hard-to-find and obsolete breakers, and we maintain stock or can source the FDB3100 through our supply network. Contact our Calgary, Edmonton, or Vancouver counters or request a quote online to check current availability.
