Product FAQs
5 answersWill the Siemens HED43B100 replace an older ITE HED43B100?
Yes. Siemens acquired ITE, and the current Siemens HED43B100 is a direct, form-fit replacement for older ITE-branded breakers bearing the exact same catalog number.
What is the difference between the Siemens ED43B100 and HED43B100?
The "H" designates a higher short-circuit interrupting capacity. The standard ED43B100 is rated at 18kAIC at 480VAC, while the HED43B100 is a high-interrupting breaker rated at 42kAIC at 480VAC.
Can the HED43B100 be used in reverse-feed applications?
Yes. Siemens ED-frame circuit breakers equipped with non-interchangeable thermal-magnetic trip units, like the HED43B100, are suitable for reverse-feed installations.
Which panelboards accept the HED43B100 breaker?
This bolt-on breaker is designed for use in Siemens Sentron P1, P2, and P3 panelboards, as well as Siemens SB switchboards. It mounts directly to the panel bus and includes load-side lugs.
Are the thermal and magnetic trip settings adjustable on this breaker?
No. The HED43B100 features fixed thermal and fixed magnetic trip elements. The long-time and instantaneous trip thresholds cannot be field-adjusted.
