Product FAQs
7 answers
Which Siemens panelboards are compatible with the HHED63B015 circuit breaker?
This bolt-on ED frame breaker is designed for use in Siemens Sentron Series panelboards, specifically the P1, P2, and P3 models, as well as compatible Siemens switchboards and standalone enclosures.
What are the acceptable wire gauges for the standard lugs on this 15A breaker?
The factory-installed lugs accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire. Ensure proper torque specifications are followed during installation as outlined on the breaker faceplate.
Is the HHED63B015 rated for direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for DC applications up to 250VDC, providing an interrupting capacity of 30kAIC at that voltage.
How does the HHED6 series differ from standard ED6 breakers?
The HH prefix designates a higher interrupting capacity within the Sentron ED frame family. While standard ED6 breakers offer lower fault current ratings, the HHED63B015 provides up to 100kAIC at 240VAC and 65kAIC at 480VAC for systems requiring higher short-circuit protection.
Can the trip settings on the HHED63B015 be adjusted in the field?
No, this specific model utilizes a fixed thermal and fixed magnetic trip unit. It does not support field adjustments for the long-time or instantaneous trip curves.
Does this breaker mount onto a standard DIN rail?
No, the HHED63B015 is a bolt-on molded case circuit breaker designed specifically for bolted connections to the busbars in Sentron panelboards and switchboards. It cannot be mounted on a DIN rail.
Can I use this breaker to replace an older ITE HHED63B015?
Yes. Siemens acquired ITE and continued manufacturing the Sentron ED frame line. A modern Siemens HHED63B015 is a direct replacement for the legacy ITE version sharing the same catalog number.
