Siemens CED63B100 Molded Case Circuit Breaker | 100A 3-Pole 600V Feed-Thru MCCB

Siemens CED63B100 — 100 Amp, 3-Pole, 600V Feed-Thru Molded Case Circuit Breaker

The Siemens CED63B100 is a heavy-duty, thermal magnetic molded case circuit breaker (MCCB) from the Siemens Sentron Series, engineered for demanding industrial and commercial power distribution applications. With an extra-high interrupting capacity of 200kAIC at 480V and 100kAIC at 600V, this breaker delivers superior overcurrent and short-circuit protection where standard-rated breakers fall short.

Built to perform in 3-phase electrical systems, the CED63B100 features a feed-thru connection type with both line and load side lug terminals — making it ideal for installations requiring pass-through wiring flexibility. Its bolt-on design ensures a secure, vibration-resistant fit in panelboards and switchgear enclosures.

Why Choose the Siemens CED63B100?

The CED63B100 stands apart from standard E-frame breakers with its extra-high interrupting rating — a critical advantage in facilities with high available fault current, such as commercial buildings, industrial plants, and utility substations. Where a standard ED63B100 is rated at 25kAIC @ 480V, the CED63B100 delivers up to 200kAIC, providing an 8x greater fault current withstand capability.

The feed-thru (Feed-Thru / "L" terminal) design allows conductors to pass through the breaker from line to load side, simplifying panel wiring and reducing installation time. Combined with Siemens' proven thermal-magnetic trip mechanism, this breaker provides reliable overload and short-circuit protection without nuisance tripping.

Typical Applications

• Industrial motor control centers (MCCs)
• Commercial and industrial panelboards
• Switchgear assemblies requiring high AIC ratings
• Main and branch circuit protection in 3-phase systems
• Data centers, manufacturing facilities, and utility distribution

CED63B100 vs. ED63B100 — What's the Difference?

The CED prefix indicates extra-high interrupting capacity, while the ED prefix is Siemens' standard interrupting version. If your application involves a high-fault-current environment, the CED63B100 is the correct choice. Always verify your system's available fault current (AFC) before selecting a breaker.
