Product FAQs
6 answersWhich panelboards are designed to accept the HEB2B025B circuit breaker?
This breaker is engineered specifically for Siemens P3, P4, and P5 series panelboards. Always verify your specific panel labeling to ensure the HEB frame is an approved branch or main device.
Can I use aluminum wire with the HEB2B025B breaker?
Yes, the factory-installed lugs are dual-rated for both copper and aluminum conductors ranging from 14 AWG to 1/0 AWG. When using aluminum wire, ensure you apply a suitable oxide inhibitor and torque the terminals to the manufacturer specifications.
What is the difference between the Siemens NEB2B025B and HEB2B025B?
The primary difference is the short-circuit interrupting rating. The HEB frame is the high interrupting capacity version, offering 65kA at 480VAC, whereas the standard NEB frame provides 35kA at 480VAC. Both share the same physical dimensions and mount in the same panels.
Are the trip settings on the HEB2B025B adjustable for custom coordination?
No, this breaker uses a fixed thermal-magnetic trip unit. The long-time and instantaneous trip functions are permanently calibrated at the factory for 25 amps and cannot be modified in the field.
Can this breaker be used in direct current applications?
Yes, unlike many standard AC breakers, the HEB2B025B is fully rated for DC systems up to 125/250VDC. It provides a 42kA interrupting capacity for these specific direct current loads.
Does the HEB2B025B provide ground fault or arc fault protection?
No, this is a standard thermal-magnetic circuit breaker designed for basic overload and short-circuit protection. It does not include GFCI or AFCI capabilities.
