The Siemens ED23B015L is a 3-pole, 15A molded case circuit breaker from the Sentron ED2 frame series. It delivers robust protection for 240VAC and 250VDC systems in industrial environments. Designed as a unit mount breaker, it installs into individual enclosures, switchboards, and feed-thru panelboards. It includes line and load side lugs, accepting 14-10 AWG copper or 12-10 AWG aluminum wire. This HACR-rated breaker features a fixed thermal-magnetic trip unit and a 10 kAIC rating at 240V.
What is the difference between the Siemens ED23B015 and the ED23B015L?
The L suffix in the ED23B015L catalog number indicates that the breaker comes factory-equipped with line and load side lugs. The standard ED23B015 is the base breaker without lugs included.
Which Siemens enclosures are compatible with the ED23B015L circuit breaker?
The ED23B015L fits into Siemens Type ED circuit breaker enclosures, such as the E2N1S (NEMA 1 surface mount), E2N1F (NEMA 1 flush mount), and E2N12K (NEMA 12 industrial).
Can the Siemens ED23B015L be reverse fed?
Yes. Because this thermal-magnetic breaker does not have specific Line and Load markings, it is suitable for reverse feeding applications.
What types of panelboards accept the ED23B015L breaker?
This unit-mount breaker is designed for use in individual enclosures, switchboards, and feed-thru panelboards. It bolts directly to the backpan rather than plugging onto a busbar.
Can the ED23B015L be used in 250VDC control circuits?
Yes, this thermal-magnetic breaker is rated for 250VDC applications and provides a 5kA interrupting rating (5kAIC) for direct current systems.
Do I need to purchase separate lugs for the ED23B015L?
No, the ED23B015L includes factory-installed line and load lugs that accommodate 14-10 AWG copper or 12-10 AWG aluminum conductors.
Are the thermal and magnetic trip settings adjustable on the ED23B015L?
No, this breaker features a fixed thermal and fixed magnetic trip unit (LI functions) that cannot be field-adjusted.
