Description
Part of the Sentron ED-frame family, this 80A unit-mount molded case circuit breaker provides reliable long-time and instantaneous (LI) protection for commercial and industrial applications. It installs into standard enclosures, motor control centers, and switchboards requiring high interrupting capacity. Rated for 100kA at 240VAC and 42kA at 480VAC, the thermal-magnetic trip unit ensures robust fault clearing. Note that this legacy model is superseded by the 3VA5180-6ED21-0AA0 series.Specifications

Product FAQs
6 answersWhat does the H in the HED42B080L catalog number indicate?
The H designates this as a high-interrupting capacity version of the standard ED4 frame. It provides elevated fault protection, delivering 42kAIC at 480VAC and 100kAIC at 240VAC for systems with higher available fault currents.
What does the L suffix mean on this Siemens breaker?
The L suffix indicates that the breaker is supplied with factory-installed line and load lugs. These standard lugs are rated to accept 10 AWG to 1/0 AWG copper or aluminum conductors.
Can the HED42B080L be used in DC electrical systems?
Yes, the thermal-magnetic trip unit is rated for DC applications up to 250VDC. It provides a 30kA interrupting capacity, making it suitable for industrial DC control circuits or battery systems.
How is this ED-frame breaker mounted?
This is a unit-mount, feed-thru circuit breaker. It fastens directly to a backpan or mounting plate using screws, rather than plugging into or bolting onto a standard panelboard busbar.
Is the HED42B080L compatible with standard residential load centers?
No. Because it is a unit-mount ED-frame breaker, it is designed for use in industrial enclosures, switchboards, and motor control centers. It will not fit in standard plug-on or bolt-on residential panels.
What type of trip protection does the HED42B080L provide?
It features a fixed thermal and fixed magnetic trip unit that delivers long-time and instantaneous (LI) protection. The thermal element handles sustained overloads, while the magnetic element clears short circuits.
