Product FAQs
7 answersCan the Siemens HGG3B030L be mounted on a DIN rail?
Yes, the HGG3B030L is a GG-frame circuit breaker designed for unit mounting. It can be independently mounted on a standard DIN rail or secured to a base plate with mounting screws without requiring additional adapters.
What is the direct replacement for the legacy Siemens HGG3B030L?
The HGG3B030L is a legacy Sentron GB/GG frame circuit breaker. Siemens has replaced it with the 3VA5130-5EC31-0AA0 from the newer 3VA molded case circuit breaker line, which offers a nearly identical footprint for easy retrofitting.
What wire sizes are compatible with the lugs on the HGG3B030L?
The factory-installed line and load lugs on this breaker accept 14 to 6 AWG copper (Cu) wire, or 12 to 6 AWG aluminum (Al) wire. Ensure proper torque specifications are followed during installation.
Are the trip settings adjustable on the HGG3B030L?
No, this breaker features a thermal-magnetic trip unit with fixed thermal (long-time) and fixed magnetic (instantaneous) settings. The trip curve cannot be adjusted in the field.
What does the "H" in the HGG3B030L part number signify?
The "H" indicates that this is the high-interrupting capacity version of the Siemens GG frame circuit breaker. While standard NGG breakers are rated for 25kAIC at 480V, the HGG3B030L provides a higher 35kAIC rating at 480V.
What type of protection does the HGG3B030L provide?
This breaker uses a thermal-magnetic trip unit to provide both long-time (thermal) protection against sustained overloads and instantaneous (magnetic) protection against short circuits.
Where is the HGG3B030L typically installed?
This unit-mount breaker is designed for use in Siemens enclosures, industrial control panels, and OEM equipment. Its compact GG-frame design allows it to be easily integrated into distribution systems and control panels.
