Description
The CED63B110 is a 3-pole, 110A molded case circuit breaker from the Siemens Sentron series, providing thermal-magnetic protection for industrial applications. This unit-mount breaker installs into Siemens Sentron panelboards and switchboards. It replaces older ED frame installations and is superseded by the 3VA6111-7HL31-0AA0. Rated 200kAIC at 480V, this current-limiting device restricts let-through energy to protect downstream circuits from severe faults.Specifications

Product FAQs
7 answersWhat panelboards are compatible with the Siemens CED63B110 circuit breaker?
The CED63B110 is designed for installation in Siemens Sentron panelboards and switchboards. It is a unit mount, feed-thru breaker that fits standard ED frame provisions.
Is the CED63B110 interchangeable with other ED frame breakers?
The CED63B110 shares the same physical footprint as other Siemens ED frame breakers, such as the ED4 and ED6. However, because it is a current limiting breaker, you must verify that your specific panelboard schedule permits the CED6 type for the required fault current ratings.
What does the current limiting designation mean for the CED63B110?
As a current limiting breaker, the CED63B110 restricts peak fault current and let-through energy before the circuit opens. This provides enhanced protection for downstream conductors and equipment, allowing it to achieve a high interrupting rating of 200kA at 480VAC.
Can the CED63B110 be used in DC electrical systems?
Yes, the CED63B110 is rated for use in DC applications. It provides an interrupting rating of 50kA at 250VDC and 30kA at 500VDC.
What wire sizes are accepted by the lugs on the CED63B110?
The standard lugs for this 110A ED frame breaker accept 3 to 3/0 AWG copper wire or 1 to 2/0 AWG aluminum wire.
What type of trip unit is installed in the CED63B110?
This breaker features a thermal magnetic trip unit with fixed thermal and fixed magnetic trip functions, providing standard long-time and instantaneous protection.
What is the difference between the Siemens ED63B110 and the CED63B110?
While both are 110A, 3-pole ED frame breakers, the CED63B110 features a current limiting construction that provides a significantly higher interrupting rating. The CED63B110 is rated for 200kA at 480VAC, whereas the standard ED63B110 has a lower short circuit rating.
