Product FAQs
6 answersWhich Siemens panelboards are compatible with the HEB1B025B circuit breaker?
This bolt-on breaker is designed for use in Siemens Sentron P1, P2, and P3 lighting and distribution panelboards.
What is the difference between Siemens NEB and HEB circuit breakers?
Both belong to the same physical frame family, but the HEB series features a higher interrupting rating (up to 100kA at 240VAC and 65kA at 277VAC) compared to the standard NEB series. The HEB1B025B is specified where higher fault current protection is required.
What wire sizes are accepted by the terminals on the HEB1B025B?
The factory-installed lugs accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation as labeled on the breaker.
Can the HEB1B025B be used in direct current (DC) systems?
Yes, this breaker is rated for DC applications up to 125VDC, providing an interrupting capacity of 42kAIC for direct current circuits.
What type of protection does the HEB1B025B provide?
It utilizes a fixed thermal magnetic trip unit with Long-Time and Instantaneous (LI) functions. The thermal element protects against sustained overloads, while the magnetic element trips instantly during short circuits.
Does this breaker require a mounting kit for installation?
The HEB1B025B is a bolt-on breaker that connects directly to the busbars in compatible Siemens panelboards. Additional twin mounting kits or strap kits may be required depending on your specific panelboard interior and whether you are adding it to an unprovisioned space.
