The FDC3040 is an Eaton 3-Pole 40 Amp 600V Molded Case Circuit Breaker, designed for optimal protection and performance in electrical systems. Featuring thermal-magnetic trip technology, it ensures reliable operation under various load conditions. Ideal for commercial and industrial applications, it delivers superior reliability and ease of installation for your electrical needs.
The FDC3040 carries a 35kA interrupt (AIC) rating at 600V. This means it can safely clear a fault of up to 35,000 amps without catastrophic failure. Before installing, confirm that the available fault current at the point of installation does not exceed this rating — a requirement under the Canadian Electrical Code (CEC). If your fault current is higher, Eaton offers higher-interrupt FDC-frame variants.
The FDC frame is a well-established Eaton MCCB series and units are available through Northern Breaker Group — both new and reconditioned stock depending on availability. We specialise in hard-to-find and obsolete breakers, so even if current production has shifted, we can typically source the FDC3040. Contact our Calgary, Edmonton, or Vancouver counters or request a quote online for lead times and availability.
Yes. The FDC3040's thermal-magnetic trip mechanism makes it suitable for motor branch-circuit protection in 600V systems, provided the breaker is sized in accordance with CEC Section 28 requirements for motor circuits. At 40A/3-Pole/600V, it is well suited to protect smaller 3-phase motors in commercial and industrial environments. Always verify that the trip curve and service factor align with the motor's full-load current and starting characteristics.
