Product FAQs
8 answersWhich panelboards are compatible with the NEB1B025B circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 series panelboards.
Can I install the NEB1B025B in a GE or Eaton panelboard?
No. Siemens NEB breakers are engineered specifically for Siemens panelboards. Installing them in other brands violates UL listings and can lead to electrical hazards.
What wire sizes and materials are accepted by the NEB1B025B lugs?
The terminals accept 14 AWG to 1/0 AWG copper or aluminum wire.
Is the NEB1B025B suitable for 277V commercial lighting circuits?
Yes, it is rated for 277VAC with a 35kA interrupting capacity, making it suitable for 277V commercial lighting and distribution applications.
Can this breaker be used in DC applications?
Yes, the NEB1B025B is rated for 125VDC with a 35kA interrupting capacity, allowing it to be used in compatible direct current systems.
Does the NEB1B025B have an adjustable trip setting?
No, it features a fixed thermal and fixed magnetic trip unit, providing non-adjustable long-time and instantaneous protection.
What is the difference between Siemens NEB and HEB breakers?
Both belong to the same frame group and share physical dimensions, but HEB breakers feature a higher interrupting capacity than standard NEB breakers.
Why use a bolt-on breaker like the NEB1B025B instead of a plug-in type?
Bolt-on breakers physically bolt to the panelboard bus bars, providing a secure, vibration-resistant connection that is required in many commercial and industrial environments.
