CED63B100 – SIEMENS 3P100A 600V BOLT ON 100kA BREAKER

A 100 kA interrupting capacity means this breaker can safely clear fault currents up to 100,000 amperes at 600 V — well above what most standard MCCBs offer. This makes the CED63B100 suitable for locations close to utility transformers or main distribution points in commercial and industrial facilities where available fault current is high. Always verify that the breaker's interrupting rating meets or exceeds the available short-circuit current at the installation point, as required by the Canadian Electrical Code (CEC).

Availability of specific Siemens CED-frame breakers can vary — some variants have been discontinued as product lines evolve. Northern Breaker Group specializes in obsolete and hard-to-find breakers, maintaining stock of legacy Siemens MCCB frames. Contact our Calgary, Edmonton, or Vancouver counter or request a quote online and our team will advise on current stock, lead times, or suitable reconditioned units.

Yes — a 3-pole, 100 A, 600 V MCCB like the CED63B100 is commonly applied as a main or sub-feed breaker in industrial panelboards and distribution sections, provided the panelboard is rated for 600 V and accepts CED-frame bolt-on devices. Confirm your panelboard's frame acceptance and main-breaker space dimensions before installation, and ensure the 100 kA interrupting rating is appropriate for your system's available fault current. Reach out to our team with your panelboard details and we'll help confirm suitability.
