Product FAQs
10 answersWhich panelboards are compatible with the Siemens HEB3B070B circuit breaker?
This bolt-on breaker is designed specifically for installation in Siemens P1, P2, and P3 series distribution panelboards.
Does the HEB3B070B breaker mount onto standard DIN rail?
No, this is a bolt-on molded case circuit breaker designed to mount directly to the busbars of compatible panelboards, not on standard DIN rail.
How are line and load connections made on the HEB3B070B?
The line side of this breaker bolts directly to the internal panelboard bus. The load side utilizes factory-installed TA1EG10 mechanical lugs for terminating outbound conductors.
Can I use aluminum wiring with the HEB3B070B circuit breaker?
Yes, the standard load-side lugs provided with this breaker are dual-rated to safely accept both copper and aluminum conductors ranging from 14 AWG up to 1/0 AWG.
Can the HEB3B070B be installed in direct current (DC) applications?
Yes, in addition to its standard alternating current ratings, this thermal magnetic breaker is approved for DC electrical systems up to 250VDC, where it provides a 42kA interrupting capacity.
Is there a way to adjust the trip curve on the HEB3B070B?
No, this specific model is built with fixed thermal and fixed magnetic trip elements. If you require field-adjustable pickup settings, you will need to specify a circuit breaker equipped with an electronic trip unit.
How does the short-circuit rating of the HEB3B070B change based on system voltage?
The interrupting capacity (AIC) scales depending on your system voltage. It provides a highly robust 100kA limit at 240V AC, steps down to 65kA at 480V AC, and safely handles up to 25kA on 600V AC or 347V AC systems.
How much space does the HEB3B070B take up in a panelboard?
This 3-pole EG-frame circuit breaker has a physical footprint of approximately 3 inches wide by 5.5 inches tall by 3 inches deep.
What frame size is the Siemens HEB3B070B?
This breaker is classified under the NEB/HEB frame group, which falls under the broader Siemens Sentron EG frame family.
Can the HEB3B070B be used to protect commercial HVAC equipment?
Yes, this breaker is HACR rated, meaning it is tested and approved for the unique inrush currents associated with heating, air conditioning, and refrigeration equipment loads.
