Product FAQs
6 answersWhich Siemens panelboards accept the HEB3B030B circuit breaker?
This breaker secures directly to the busbars of Siemens P3, P4, and P5 panelboards using a standard bolt-on connection.
Can the HEB3B030B be used to upgrade an existing NEB frame breaker?
Yes, HEB and NEB breakers share identical physical dimensions and panelboard mounting styles. Upgrading to the HEB3B030B provides a higher short-circuit interrupting rating of 65kA at 480VAC, compared to the standard 35kA rating of the NEB series.
What conductor sizes and materials do the factory lugs accept?
The factory-installed connections on this breaker accept 14 AWG through 1/0 AWG copper (Cu) or aluminum (Al) wire.
Is this circuit breaker approved for direct current (DC) systems?
Yes, the HEB3B030B is rated for use in DC applications up to 250VDC, where it provides a 42kA interrupting capacity.
Is the HEB3B030B HACR rated for HVAC loads?
Yes, this molded case circuit breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment circuits.
Are the thermal and magnetic trip settings adjustable on this model?
No, this unit features a fixed thermal and fixed magnetic trip mechanism for long-time and instantaneous (LI) overcurrent protection. If your application requires field-adjustable trip curves, you will need to select a breaker with an electronic trip unit.
