Description
Engineered for high-fault environments, the Siemens CED63B070L is a 70A, 3-pole current-limiting MCCB. It provides robust thermal-magnetic protection for commercial applications, restricting let-through energy to safeguard downstream equipment. This ED frame breaker mounts into Siemens Sentron panelboards. It features a unit mount configuration and includes factory-installed line and load lugs. Rated for an impressive 200kAIC at 480VAC and 100kAIC at 600VAC, it ensures reliable performance.Specifications

Product FAQs
6 answersWhich enclosures are compatible with the CED63B070L?
This ED frame breaker is designed for Siemens Sentron panelboards and switchboards. Because it is a unit mount, feed-thru breaker, it mounts independently rather than plugging or bolting directly onto a panelboard bus.
Will the CED63B070L fit in standard ED frame spaces?
Yes. The CED63B070L belongs to the Siemens 125A ED frame family. It shares the same physical dimensions and mounting footprint as standard ED4 or ED6 breakers, but its current-limiting design provides higher interrupting ratings.
Can the CED63B070L replace older Siemens CE or CLE series breakers?
Yes. Siemens identifies CED6 breakers as mechanically and electrically interchangeable with legacy CLE breakers. They also serve as a qualified replacement path for older CE frame models.
What does the L suffix in the CED63B070L catalog number indicate?
The L suffix means the breaker comes with factory-installed line and load lugs. These lugs are rated to accept 10 AWG to 1/0 AWG copper or aluminum wire.
What does the Current Limiting designation mean for this breaker?
As a current-limiting breaker, the CED63B070L clears high-level short circuits in a fraction of a cycle. This rapid action reduces peak let-through current and energy, providing enhanced protection for downstream electrical equipment.
Are the thermal and magnetic trip settings adjustable on the CED63B070L?
No. This breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory-set and cannot be adjusted in the field.
