Product FAQs
5 answersHow is the HED43B110L mounted in an enclosure?
This is a unit mount, feed-thru circuit breaker. Instead of plugging into a panelboard busbar, it bolts directly to a backpan or mounting plate. It is compatible with Siemens enclosures, switchboards, and motor control centers designed for ED frame breakers.
What does the "L" suffix mean in the HED43B110L catalog number?
The "L" suffix indicates that the breaker is supplied with both line and load side lugs factory installed.
What is the difference between ED4 and HED4 circuit breakers?
HED4 breakers are the high interrupting capacity version of the standard ED4 frame. While a standard ED4 is rated for 18kA at 480VAC, the HED43B110L is rated for 42kA at 480VAC.
Can the Siemens HED43B110L be reverse fed?
Yes, this ED frame circuit breaker features a non-interchangeable trip unit and is suitable for reverse feed applications.
Is the HED43B110L HACR rated?
