Description
Engineered for commercial power distribution, the Siemens NEB3B100B is a 100A molded case circuit breaker from the SENTRON family. It provides robust thermal-magnetic protection for demanding industrial electrical systems. This three-pole MCCB bolts into Siemens P1, P2, and P3 panelboards. For future replacements, this model crosses over to the newer 3VA4110-5ED34-0AA0 breaker. It delivers 85kAIC at 240V and 35kAIC at 480V. The unit is HACR rated and accepts 8-1/0 AWG wire.Specifications

Product FAQs
7 answersWhat panelboards are compatible with the Siemens NEB3B100B?
This NEB frame breaker is specifically designed for bolt-on installation in Siemens P1, P2, and P3 commercial panelboards. It is not compatible with standard load centers.
Are the load lugs included with the breaker, or sold separately?
Load-side lugs are included as standard factory hardware with the NEB3B100B breaker.
What wire sizes do the lugs on the NEB3B100B accept?
The factory-installed load lugs accommodate either copper or aluminum wire, accepting conductor sizes from 8 AWG up to 1/0 AWG.
Can the NEB3B100B be used on direct current (DC) circuits?
Yes, this breaker is fully rated for DC applications up to 250VDC, offering an interrupting capacity of 35kAIC for direct current systems.
What type of 600V systems can this breaker be installed in?
The NEB3B100B is slash-rated for 600Y/347VAC networks. This means it is suitable for solidly grounded wye systems at this voltage, where it provides a 22kAIC interrupting rating.
Is the trip curve adjustable on the NEB3B100B?
No, this breaker utilizes a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip points are factory set and cannot be adjusted in the field.
What is the direct replacement for the NEB3B100B?
Siemens is transitioning legacy NEB breakers to the newer 3VA series. The modern cross-reference for this 100A model is the 3VA4110-5ED34-0AA0, which provides the same fit and function for P-series panelboards.
