Description
Belonging to the Sentron ED frame family, this 3-pole, 50A MCCB provides reliable thermal-magnetic protection for commercial and industrial applications. The unit-mount breaker installs into Siemens enclosures, switchboards, and machinery. It comes factory-equipped with line and load lugs for straightforward wire termination. Featuring a current-limiting design, it delivers an exceptional 200kAIC rating at 480VAC to restrict let-through energy and protect sensitive downstream equipment.Specifications

Product FAQs
5 answersWhat does the L suffix in the CED63B050L part number indicate?
The L suffix means the breaker is factory-supplied with both line and load side lugs installed. Standard ED frame breakers typically only include load side lugs unless this suffix is specified.
Does this breaker plug into a panelboard busbar?
No, the CED63B050L is a unit-mount, feed-thru breaker. It bolts directly to the chassis of Siemens enclosures, switchboards, or machinery rather than plugging into a standard panelboard bus.
How does the current-limiting feature of this breaker work?
As a current-limiting breaker, it is engineered to clear short circuits extremely fast. This restricts the peak let-through energy, which helps protect sensitive downstream equipment from thermal and magnetic stress during a fault.
Can the CED63B050L be reverse fed?
Yes. Because this ED frame breaker features a fixed, non-interchangeable thermal-magnetic trip unit, it is approved by Siemens to be reverse connected for applications that require power to flow from the load side to the line side.
What frame size family does the CED63B050L belong to?
It is part of the Siemens Sentron ED frame family, which supports molded case circuit breakers up to 125 amps.
