Product FAQs
5 answersCan I install the NEB3B070B in a standard residential load center?
No. The NEB3B070B is a bolt-on molded case circuit breaker designed specifically for commercial Siemens P1, P2, and P3 panelboards. It will not fit in standard residential plug-on load centers.
Does the NEB3B070B include both line and load lugs?
No. Because it is a bolt-on breaker, the line side bolts directly to the panelboard bus. It only includes factory-installed lugs on the load side.
Can I use this to replace an older ITE NEB3B070B breaker?
Yes. Siemens acquired ITE, and this current production breaker is the exact direct replacement for legacy ITE NEB3B070B models.
Is the NEB3B070B suitable for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment.
Can this breaker be used in direct current (DC) systems?
Yes, the NEB3B070B is rated for up to 250 VDC with a 35 kA interrupting capacity, allowing it to be used in compatible commercial DC applications.
