Product FAQs
6 answersIs the Siemens HED43B080L still in active production, or is there a direct replacement?
The HED43B080L is a legacy Sentron ED frame breaker. For newer installations, Siemens recommends the 3VA5180-6EC36-0AA0 as the modern equivalent.
What does the L suffix indicate on the HED43B080L catalog number?
The L suffix indicates that the breaker is supplied with both line and load side lugs factory installed. Standard ED frame breakers without this suffix typically include load side lugs only.
Can the HED43B080L be reverse fed?
Yes. Because this ED frame breaker features a non-interchangeable trip unit, it is suitable for reverse feed applications according to UL 489 standards.
Are the trip units on the HED43B080L interchangeable?
No. Like all Siemens ED frame circuit breakers, the HED43B080L features a fixed, non-interchangeable thermal magnetic trip unit.
How does the HED43B080L mount inside an enclosure or panel?
This is a unit mount, feed-thru circuit breaker. It bolts directly to the mounting surface or backpan in standard enclosures, switchboards, and motor control centers, rather than plugging onto a busbar.
How is the HED43B080L wired for 250VDC applications?
When applying this 3 pole thermal magnetic breaker on a 250VDC system, typically two poles are used, wiring one pole on each leg of the DC supply circuit to achieve the 30kA interrupting rating.
