The Siemens CED63B050 is a molded-case circuit breaker (MCCB) from the Siemens CED63B frame series — rated 3-Pole, 50A, 600V AC, 100kA interrupting capacity with a bolt-on mounting configuration. As a commercial/industrial MCCB, it is designed to mount in Siemens compatible panelboards and switchboards that accept the CED63B frame, not in residential loadcentres. It is suitable for use in branch, feeder, and main protection applications in commercial and industrial installations up to 600V.
Frame and panelboard compatibility can vary — send us your panelboard model and we'll confirm the fit.
The CED63B050 carries a 100kA interrupting (AIC) rating at 600V. This means it can safely clear fault currents up to 100,000 amperes without catastrophic failure. For commercial and industrial installations where available fault current can be very high — particularly close to utility transformers or large distribution equipment — selecting a breaker with an adequate AIC rating is a critical code and safety requirement. Always verify the available fault current at the point of installation.
Yes, provided your panelboard accepts the CED63B frame series and the bolt-on mounting style. When replacing an existing breaker, confirm the frame size, pole configuration, voltage rating, and mounting style match the original. If you're unsure whether your panelboard is compatible, contact Northern Breaker Group with your panelboard model number and we'll verify the fit before you order.
Yes — sourcing obsolete and hard-to-find breakers is a Northern Breaker Group speciality. If you need a specific ampere rating, trip configuration, or accessory (such as shunt trips, auxiliary contacts, or lug kits) within the CED63B frame, reach out to our Calgary, Edmonton, or Vancouver counter teams for availability and a quote.
