Product FAQs
7 answersWhat is the difference between the Siemens ED43B080 and the ED43B080L?
The L suffix in the ED43B080L catalog number indicates that the breaker comes factory-equipped with line and load side lugs (part number LN1E100). The standard ED43B080 does not include these lugs by default.
Is there a modern replacement for the ED43B080L?
Yes, the Siemens 3VA5180-4ED36-0AA0 is the direct modern replacement for this legacy ED frame breaker.
Is the ED43B080L HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment.
Can the ED43B080L be reverse fed?
Yes, like all Siemens ED frame circuit breakers, the ED43B080L is reverse feed capable. This allows power to be supplied to either the line or load terminals.
What wire sizes are compatible with the included lugs on the ED43B080L?
The factory-installed LN1E100 lugs accept 10 AWG to 1/0 AWG copper or aluminum wire.
What type of enclosures or panels accept the ED43B080L?
This is a unit mount breaker designed for individual enclosures, switchboards, and motor control centers that accept Siemens Sentron ED frame breakers. It is not a plug-on breaker for standard residential load centers.
Can the ED43B080L be used in DC power systems?
Yes, this thermal magnetic breaker is rated for up to 250VDC with an interrupting capacity of 30kAIC, making it suitable for specific direct current applications.
