Product FAQs
5 answersWhich Siemens panelboards are compatible with the NEB3B035B circuit breaker?
This bolt-on breaker is designed for installation in Siemens P1, P2, and P3 panelboards, as well as legacy NEB panelboards.
What wire sizes and materials are supported by the load lugs on this breaker?
The factory-installed load lugs accept 14 AWG through 1/0 AWG wire. They are rated for use with both copper (Cu) and aluminum (Al) conductors.
Can the NEB3B035B be used in DC voltage applications?
Yes, this breaker is UL and CSA listed for DC applications up to 125/250 VDC, providing a 35 kA interrupting rating at that voltage.
Are the thermal and magnetic trip settings adjustable on this model?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory set and non-adjustable.
Will this Siemens breaker replace an older ITE NEB series breaker?
Yes. Siemens acquired ITE and continues to manufacture the NEB series to the same physical dimensions and bolt-on mounting specifications, making it a direct replacement for legacy ITE versions.
