Product FAQs
9 answersWhich Siemens panelboards accept the HEB3B080B circuit breaker?
This bolt-on molded case circuit breaker is designed specifically for installation in Siemens P3, P4, and P5 commercial panelboards.
Can the HEB3B080B be installed in a standard residential load center?
No. The HEB3B080B is a commercial bolt-on branch breaker. It lacks the plug-on mounting design required for standard residential load centers.
What is the difference between the Siemens NEB and HEB breaker frames?
Both belong to the same physical frame group, but the HEB series features a higher interrupting capacity for systems requiring higher fault current ratings.
Why does the HEB3B080B only include lugs on one side?
As a bolt-on breaker, the line side mounts directly to the panelboard bus with bolts. It only requires and includes factory-installed lugs on the load side for wire termination.
Can I use both copper and aluminum wire with the standard lugs?
Yes, the factory-installed load lugs accept both copper and aluminum conductors. The accepted wire range is 14 to 1/0 AWG for copper and 12 to 1/0 AWG for aluminum.
Is the HEB3B080B circuit breaker rated for reverse feeding?
Yes, this model features a reverse-feed capable design, meaning it can be wired with the line or load on either set of terminals without compromising its protective functions.
Is there a newer catalog replacement for the HEB3B080B?
Yes, for facility maintenance and panel upgrades, the older HEB3B080B is frequently superseded by the newer Siemens HEG3B080B model.
Can this breaker be used to protect HVAC equipment?
Yes, the HEB3B080B is HACR rated, making it fully approved for use with heating, air conditioning, and refrigeration equipment that requires an 80-amp breaker.
Does the HEB3B080B feature a trip-free mechanism?
Yes, it includes a trip-free mechanism that ensures the breaker will trip during an overcurrent event or short circuit, even if the operating handle is physically held in the ON position.
