Product FAQs
5 answersDoes the HHED63B050L come with lugs, and what wire sizes do they accept?
Yes, the L suffix in the catalog number indicates this breaker is factory-equipped with both line and load side lugs. These lugs accept 10 AWG to 1/0 AWG copper or aluminum wire.
How does a unit mount breaker like the HHED63B050L install into a system?
As a unit mount (feed-thru) breaker, it fastens directly to a backpan or enclosure mounting surface using screws or bolts, rather than plugging into a panelboard busbar. It is commonly used in custom control panels, switchboards, and standalone enclosures.
Can the Siemens HHED63B050L be reverse fed?
Yes. Because this ED frame breaker features a non-interchangeable trip unit, it is suitable for reverse feed applications where power flows from the bottom terminals to the top terminals.
Are the trip settings on this 50A breaker adjustable?
No, the HHED63B050L features a fixed thermal and fixed magnetic trip unit. Neither the long-time overload nor the instantaneous short-circuit trip functions can be adjusted in the field.
What is the difference between the HHED63B050 and the HHED63B050L?
The standard HHED63B050 typically ships with load side lugs only. The L suffix on the HHED63B050L means it includes both line and load side lugs pre-installed from the factory.
