Product FAQs
6 answersWhich panelboards accept the Siemens HED43B080 circuit breaker?
This ED-frame breaker mounts into Siemens Sentron P1, P2, P3, P4, and P5 panelboards, as well as compatible Siemens switchboards.
What wire sizes and materials are supported by the HED43B080 load lugs?
The factory-installed load lugs accept 10 to 1/0 AWG copper or aluminum conductors.
What is the difference between the Siemens ED43B080 and the HED43B080?
The primary difference is the short-circuit interrupting rating. The HED43B080 is a high-interrupting breaker rated for 42kAIC at 480VAC, while the standard ED43B080 is rated for 18kAIC at 480VAC.
Is the HED43B080 suitable for direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for DC applications, providing a 30kA interrupting capacity at 250VDC.
Are the trip settings on the HED43B080 adjustable?
No, this breaker utilizes a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions.
Can line-side lugs be added to the HED43B080 for standalone applications?
Yes. While it is designed as a bolt-on breaker for panel bus connections, line-side lugs (such as the LN1E100 kit) can be installed in the field for use in individual enclosures.
