With a robust 100kA interrupting capacity, this bolt-on breaker ensures reliable protection for your electrical systems. Ideal for industrial and commercial environments, it offers peace of mind with superior durability and fault management features.
The CFD63B175 is a bolt-on MCCB in the Siemens CFD frame and is designed for commercial and industrial panelboards and switchboards that accept this frame — not residential loadcentres. Specific compatibility depends on your board's busbar configuration and frame acceptance. Send us your panelboard model number and we'll confirm whether the CFD63B175 is the right fit.
Siemens CFD-frame breakers can be difficult to source as the product line ages. Northern Breaker Group specialises in obsolete and hard-to-find breakers, maintaining stock of legacy Siemens MCCBs across our Calgary, Edmonton, and Vancouver locations.

Yes — upgrading to a higher interrupting rating (100kA versus a lower-rated predecessor) is generally acceptable provided the replacement breaker matches the panel's frame requirements and the 175A, 3-pole, 600V ratings suit the circuit. However, always verify the panelboard's listed breaker types and consult a licensed electrician to ensure the installation meets Canadian Electrical Code (CEC) requirements.
