The CFD63B225 is a robust Siemens 3 Pole 225 Amp circuit breaker designed for 600V applications. With a high interrupting capacity of 100kA, this bolt-on breaker ensures optimal protection for your electrical systems. Ideal for industrial settings, it’s engineered for reliability and performance, making it a perfect choice for your power distribution needs.
The CFD63B225 is an industrial bolt-on MCCB designed for Siemens commercial and industrial panelboards and switchboards that accept CFD-frame breakers at 600V, 3-phase — not residential loadcentres. Typical applications include Siemens S1 and P1-series panelboards, but compatibility depends on your specific board's bus and frame ratings. Contact our team with your panelboard model number and we'll confirm the fit.
The 100kA symmetrical interrupting capacity means the CFD63B225 can safely clear fault currents up to 100,000 amperes at 600V without damage to the breaker or the surrounding equipment. This high AIC rating makes it well suited for industrial facilities fed from large transformers or utility services where available fault current is elevated — a common requirement in Canadian commercial and heavy industrial installations per the Canadian Electrical Code (CEC).
Yes — Northern Breaker Group specializes in sourcing hard-to-find and obsolete Siemens MCCB frames, including the CFD series. The CFD63B225 can serve as a direct replacement for an existing CFD-frame 225A 3-pole 600V bolt-on breaker, provided the interrupting rating and mounting configuration match your panelboard. Reach out to us for availability and to verify your replacement requirements.
