Product FAQs
6 answersWhat type of panelboards accept the HED43B030 circuit breaker?
This bolt-on breaker is designed specifically for Siemens Sentron P2 and P3 panelboards, as well as compatible Siemens switchboards. It is not interchangeable with other Siemens frame sizes like the FD or JD frames.
What is the difference between the HED43B030 and the standard ED43B030?
The primary difference is the short-circuit interrupting rating. Both are 30-amp, 3-pole ED-frame breakers, but the standard ED43B030 provides 18kAIC at 480VAC. The HED43B030 is the high-interrupting variant, providing 42kAIC at 480VAC.
Which lug kit is standard for the HED43B030 breaker?
This breaker typically utilizes the LN1E100 lug kit on the load side. The LN1E100 lugs are designed to accommodate both copper and aluminum conductors ranging from 10 AWG to 1/0 AWG.
Can the Siemens HED43B030 be reverse fed?
Yes, standard thermal-magnetic ED-frame breakers can generally be reverse connected. However, installers must verify the physical breaker to ensure there are no factory Line and Load markings that would restrict backfeeding.
Can I adjust the trip settings on the HED43B030?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The Long-Time and Instantaneous (LI) protection levels are factory-calibrated and cannot be field-adjusted.
What is the Siemens catalog number format for this breaker with factory-installed lugs?
While HED43B030 represents the base breaker, you may see it listed with an L suffix, such as HED43B030L, when ordered from the factory with the load-side lugs pre-installed.
