Product FAQs
7 answersWhat does the "L" suffix indicate in the ED63B045L catalog number?
The "L" suffix signifies that the breaker is factory-supplied with both line and load side lugs. Standard ED frame breakers without this suffix are typically shipped with load side lugs only.
Can the Siemens ED63B045L be reverse fed?
Yes. Because it features a fixed, non-interchangeable thermal-magnetic trip unit, this ED frame circuit breaker is suitable for reverse feed applications.
Is there a modern replacement for the ED63B045L?
Yes, Siemens replaces this legacy Sentron breaker with the 3VA series, specifically catalog number 3VA5145-4ED31-0AA0. Note that the 3VA replacement requires a separate lug kit, whereas the ED63B045L includes them.
Is this circuit breaker HACR rated?
Yes, it carries a HACR rating, meaning it is approved for use with heating, air conditioning, and refrigeration equipment branch circuits.
What equipment is this ED frame breaker compatible with?
As a unit mount breaker, it is designed for installation in Siemens Sentron switchboards, panelboards, and approved individual enclosures rather than standard plug-on load centers.
What is the catalog number for replacement lugs?
The standard replacement lug kit for this breaker is LN1E100. These lugs accept 10 AWG to 1/0 AWG copper or aluminum wire and can be used on both the line and load sides.
Can this breaker be used in direct current (DC) systems?
Yes, it is rated for up to 250VDC with an interrupting capacity of 30kA. When applied on 250VDC systems, standard Siemens guidelines require wiring one pole on each leg of the supply circuit.
