Product FAQs
6 answersWhich Siemens panelboards are compatible with the NEB2B030B breaker?
This bolt-on breaker is designed for use in Siemens Sentron P1, P2, P3, P4, and P5 panelboards. Proper mounting hardware or strap kits may be required depending on the specific panelboard type and generation.
What wire sizes and materials are accepted by the lugs on this breaker?
When terminating conductors on the NEB2B030B, the standard factory-installed lugs accept 14 AWG to 1/0 AWG copper (Cu) or aluminum (Al) wire. Ensure proper torque is applied per the label on the breaker during installation.
Can the NEB2B030B be utilized in direct current (DC) systems?
Yes, this thermal magnetic breaker is rated for DC applications up to 250VDC, providing an interrupting capacity of 35kAIC at that voltage.
How does the NEB frame compare to the HEB frame?
The NEB and HEB frames share the same physical footprint and panelboard compatibility. The primary difference is the interrupting rating. HEB breakers offer a higher short-circuit current rating (65kAIC at 480VAC) compared to the NEB series (35kAIC at 480VAC).
Does this breaker include mounting hardware for panelboard installation?
The NEB2B030B is supplied with standard load-side lugs. Panelboard mounting hardware, such as twin mounting kits or strap kits, is typically sold separately and depends on the specific panelboard model.
What type of trip unit is installed in the NEB2B030B?
It features a fixed thermal magnetic trip unit with Long-Time and Instantaneous (LI) protection. The trip settings are factory-calibrated and non-adjustable.
