Engineered for high-fault environments, the CED63B015 is a 3-pole, 15A current-limiting MCCB from the Siemens Sentron series. By rapidly interrupting short circuits, it reduces let-through current to protect sensitive electrical distribution systems. This unit-mount breaker fits Siemens P1, P2, and P3 panelboards and standard switchboards. It includes load-side lugs for streamlined wiring. With a 200kAIC rating at 480VAC, it handles severe faults and complies with UL 489.

Product FAQs
6 answers
Which Siemens panelboards are compatible with the CED63B015?
This breaker is designed for use in Siemens Sentron series panelboards, specifically types P1, P2, and P3, as well as compatible switchboards. It utilizes a bolt-on unit mount configuration.
How does the current limiting feature of the CED63B015 benefit my electrical system?
As a current limiting breaker, it rapidly clears high-level faults to reduce the peak let-through current and energy. This protects downstream equipment from severe thermal and mechanical stress during a short circuit.
What are the acceptable wire sizes for the standard lugs on this 15A breaker?
The factory installed lugs accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire. Ensure proper torque specifications are followed during installation.
How does the CED frame differ from standard ED frame breakers?
The CED frame belongs to the Siemens ED frame group but is specifically engineered as a current limiting breaker. It provides much higher interrupting ratings, such as 100kA at 600VAC, compared to standard ED4 or ED6 breakers.
Can I adjust the trip settings on the CED63B015?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long time and instantaneous protection settings are factory calibrated for 15 amps and cannot be modified in the field.
Is this breaker suitable for direct current applications?
Yes, it is rated for DC systems up to 500VDC. It provides an interrupting capacity of 50kA at 250VDC and 30kA at 500VDC, making it suitable for specific industrial DC applications.
