Product FAQs
5 answersWhat panelboards are compatible with the Siemens HEB3B025B?
The HEB3B025B is a bolt-on molded case circuit breaker designed for use in Siemens P1, P2, and P3 commercial and industrial panelboards. It is not compatible with standard residential plug-on load centers.
What is the difference between the Siemens HEB and NEB frame breakers?
The H in the HEB frame designates it as the high-interrupting tier within the EG frame family, providing up to 65kAIC at 480VAC. The NEB frame is the standard-interrupting version. Both share the same physical dimensions and panelboard compatibility.
What wire sizes and materials do the lugs on the HEB3B025B accept?
The factory-installed lugs accept 14 AWG through 1/0 AWG copper or aluminum conductors. Always ensure proper torque specifications are met during installation as labeled on the breaker.
Does the HEB3B025B provide ground fault or arc fault protection?
No, this breaker features standard thermal-magnetic trip functions (Long-Time and Instantaneous) for overload and short-circuit protection. It does not include GFCI or AFCI circuitry.
Is the HEB3B025B suitable for direct current (DC) applications?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, where it provides an interrupting capacity of 42kAIC.
