Product FAQs
5 answersWhich panelboards are compatible with the NEB2B070B circuit breaker?
This bolt-on circuit breaker is designed for use in Siemens P1, P2, and P3 series panelboards. It mounts directly to the panel bus using a bolted connection, ensuring a secure fit for commercial and industrial distribution.
What wire sizes are accepted by the lugs on this 70A breaker?
The factory-installed lugs accept 14 AWG to 1/0 AWG copper or aluminum conductors. Always verify that your selected wire gauge meets local electrical codes for a 70-amp circuit.
Can the NEB2B070B be used in DC electrical systems?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for DC applications up to 250V DC with a 35kAIC rating. This makes it suitable for specific industrial control or battery backup circuits.
What is the difference between Siemens NEB and HEB frame circuit breakers?
Both are part of the Siemens Sentron family and share the same physical dimensions and bolt-on mounting. The primary difference is the interrupting rating. The NEB frame provides standard interrupting capacity, while the HEB frame offers higher interrupting ratings for systems with greater available fault current.
Are the trip settings adjustable on the NEB2B070B?
No, this breaker features fixed thermal and fixed magnetic trip functions for both long-time and instantaneous protection. If your application requires adjustable trip curves, you will need to select a breaker with an electronic trip unit.
