Description
Engineered for commercial power distribution, the Siemens HGG3B080L is an 80A, 3-pole molded case circuit breaker with a high interrupting capacity of 35kA at 480V. It utilizes a fixed thermal-magnetic trip mechanism to provide LI protection. This unit-mount breaker is designed to fit Siemens P1, P2, and P3 panelboards. It features a DIN-rail mountable footprint and includes standard lugs. For future upgrades, it is replaced by the 3VA5180-5EC31-0AA0 (requires a panelboard retrofit kit).Specifications

Product FAQs
8 answersWhich Siemens panelboards accept the HGG3B080L breaker?
This breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as compatible switchboards and enclosures that accommodate SENTRON GB or GG frame unit mount breakers.
Can I use the HGG3B080L to replace an older Siemens or ITE GB frame breaker?
Yes, the HGG frame shares the same physical footprint and mounting configuration as legacy Siemens and ITE GB and GG frame breakers, making it a suitable replacement provided the voltage and interrupting ratings meet your system requirements.
How does the HGG frame differ from the standard GG frame?
The HGG designation indicates a high-interrupting capacity version of the standard GG frame. It provides elevated fault protection, including 65kA at 240VAC and 35kA at 480VAC.
What are the acceptable wire sizes for the factory lugs?
The included lugs accept 8 AWG to 1/0 AWG copper conductors, or 8 AWG to 2/0 AWG aluminum conductors.
Is this breaker suitable for DC voltage systems?
Yes, the HGG3B080L is rated for use in 250VDC systems and provides an interrupting rating of 14kA at that voltage.
Can I adjust the trip curve settings on this breaker?
No, this model features fixed thermal (long-time) and fixed magnetic (instantaneous) trip elements. Neither setting is field-adjustable.
Does this unit plug onto a panelboard busbar?
No, this is a unit mount, feed-thru circuit breaker. It must be bolted directly to the mounting surface or chassis and wired via the lugs, rather than plugging directly into a panelboard bus.
Does the HGG3B080L include equipment ground fault protection?
No, this is a standard thermal magnetic breaker designed for overload and short circuit protection. It does not contain ground fault (GFPE or GFCI) sensing capabilities.
