Product FAQs
8 answers
What panelboards are compatible with the HHED63B030 circuit breaker?
This bolt-on ED-frame breaker is designed for installation in Siemens P1, P2, and P3 panelboards, as well as compatible Siemens switchboards.
Can this breaker be installed in a residential plug-on load center?
No. The HHED63B030 is a bolt-on breaker built for commercial and industrial distribution equipment. It will not fit in standard residential plug-on load centers.
Is the Siemens HHED63B030 HACR rated?
Yes. Like most Siemens Sentron ED-frame circuit breakers, the HHED63B030 is HACR rated, meaning it is approved for use with dedicated heating, air conditioning, and refrigeration equipment.
What is the accepted wire size range for the lugs on this breaker?
The standard factory-installed load lugs accept 10 AWG through 1/0 AWG copper or aluminum conductors.
Are line-side lugs included with this catalog number?
No. The standard HHED63B030 is a bolt-on breaker and includes load-side lugs only, as the line side bolts directly to the panel busbar. Models requiring factory-installed line and load lugs typically feature an "L" suffix in the catalog number.
Is the HHED63B030 suitable for reverse feed applications?
Yes. Standard Siemens ED-frame molded case circuit breakers are suitable for reverse feed applications, allowing power to be supplied to the load side terminals if required by the installation.
Can the trip settings on the HHED63B030 be adjusted?
No. This thermal-magnetic breaker features fixed thermal and fixed magnetic trip elements. The long-time and instantaneous trip functions are factory calibrated and cannot be field adjusted.
Does this breaker provide equipment ground fault protection?
No. The HHED63B030 is a standard thermal-magnetic breaker that provides overload and short-circuit protection. It does not include built-in ground fault or arc fault sensing capabilities.
