Product FAQs
6 answersWhich Siemens panelboards are compatible with the HEB3B110B circuit breaker?
This bolt-on branch breaker is specifically designed to mount in Siemens Sentron P3, P4, and P5 commercial panelboards.
Are load-side lugs included with the HEB3B110B, and what is their wire capacity?
Yes, this model typically comes equipped with TA1EG10 load-side lugs. These lugs accept 14 AWG to 1/0 AWG copper or aluminum conductors. Since it is a bolt-on breaker, the line side connects directly to the panelboard bus.
What type of trip unit is installed in the HEB3B110B?
It features a non-adjustable thermal-magnetic trip unit. The "LI" trip function code indicates it provides standard, fixed Long-Time (thermal overload) protection and fixed Instantaneous (magnetic short-circuit) protection.
Can the HEB3B110B be utilized in DC power applications?
Yes. In addition to its standard AC voltage ratings, this breaker is certified for DC power systems, providing up to a 42 kA interrupting rating at 125/250VDC.
What is the difference between the Siemens HEB3B110B and the NEB3B110B?
Both are 110-amp, 3-pole EG-frame panelboard breakers. However, the HEB3B110B is the high-interrupting capacity model (rated 65 kAIC at 480VAC), whereas the NEB3B110B is the standard-capacity model (rated 35 kAIC at 480VAC).
Which overall frame family does the HEB3B110B belong to?
The HEB3B110B is part of the Siemens Sentron series and falls under the global EG-frame classification.
