Description
Designed for flexible integration, the Siemens CED63B040L is a 3-pole, 40A current-limiting molded case circuit breaker. Unlike standard bolt-on models, this ED Frame breaker features a unit-mount configuration and includes both line and load lugs (LN1E100) for straightforward feed-thru wiring. It delivers exceptional protection for commercial and industrial networks, boasting a 200 kAIC rating at 480VAC to significantly reduce let-through current and protect sensitive equipment.Specifications

Product FAQs
8 answersWhich panelboards are compatible with the CED63B040L?
This ED frame breaker is compatible with Siemens Sentron panelboards and switchboards designed to accept unit-mount, current limiting circuit breakers.
What are the wire size requirements for the terminal lugs?
The factory installed lugs on this breaker accommodate wire sizes ranging from 10 AWG to 1/0 AWG. Both copper (Cu) and aluminum (Al) conductors are supported.
What is the advantage of the current limiting feature on this breaker?
As a current limiting breaker, it is engineered to clear a fault in less than half a cycle. This rapid action significantly reduces the let-through energy and peak current, providing enhanced protection for downstream electrical components.
How does the CED6 series compare to standard ED frame breakers?
The CED6 series features ultra-high interrupting ratings, such as 200kAIC at 480VAC, and includes current limiting capabilities. Standard ED4 or ED6 breakers have lower fault-clearing capacities and lack the current limiting designation.
Can the CED63B040L be mounted on a standard DIN rail?
No. This is a unit-mount circuit breaker designed to be bolted directly to the chassis or mounting pan of a panelboard or switchboard. It is not compatible with DIN rail mounting systems.
Are the trip settings on this breaker adjustable?
No. This model features a fixed thermal and fixed magnetic trip unit. Neither the long time overload nor the instantaneous short circuit trip functions can be adjusted in the field.
Is this breaker suitable for use in DC electrical systems?
Yes. In addition to its AC ratings, this breaker is certified for DC applications. It provides an interrupting capacity of 50kA at 250VDC and 30kA at 500VDC.
What does the L suffix in the catalog number indicate?
The L suffix in the CED63B040L catalog number signifies that the breaker is supplied with factory installed line and load lugs. This ensures it is ready for immediate wire termination upon installation.
