A reliable solution for commercial facilities, the Siemens NEB2B060B is a 60A molded case circuit breaker with fixed thermal and magnetic trip units. It provides essential long-time and instantaneous protection for single-phase applications. Designed for seamless integration, it mounts into Siemens P1, P2, P3, P4, and P5 panelboards. The 3VA4160-5ED24-0AA0 is the designated replacement, requiring a mounting strap kit. This HACR-rated breaker offers an 85kAIC interrupt capacity at 240VAC.
Which Siemens panelboards accept the NEB2B060B circuit breaker?
This bolt-on breaker mounts into Siemens P1, P2, P3, P4, and P5 panelboards.
What does the B suffix in the NEB2B060B catalog number mean?
The B at the end of the part number indicates that the breaker includes factory-installed load-side lugs.
Is there a direct replacement for the NEB2B060B?
Yes, the Siemens 3VA4160-5ED24-0AA0 is the designated modern replacement. Keep in mind that installing the 3VA series breaker in legacy panels will require a compatible mounting strap kit.
Can I use the NEB2B060B to replace an older ITE breaker?
Yes. Siemens acquired ITE, and the NEB2B060B is the exact same breaker previously sold under the ITE brand. It serves as a direct replacement for legacy ITE NEB frame breakers with the same specifications.
Is the NEB2B060B suitable for direct current (DC) systems?
Yes, it is rated for use in DC applications up to 250VDC, where it provides a 35kA interrupting capacity.
How does the NEB frame compare to the HEB frame?
Both frames share the same physical footprint and panelboard compatibility, but the HEB frame provides a higher interrupting capacity. The NEB2B060B is rated for 35kA at 480VAC, while the equivalent HEB breaker is rated for 65kA at 480VAC.
What are the acceptable wire sizes for the NEB2B060B terminals?
The included load lugs accommodate wire gauges from 14 AWG up to 1/0 AWG. Both copper (Cu) and aluminum (Al) conductors are supported.
Do I need a separate hardware kit to mount this breaker?
Yes, installing this breaker into a Siemens panelboard requires a specific branch mounting hardware kit, such as the NEB65K for twin branch configurations, depending on your exact panel model.
