Product FAQs
5 answersHow is the HGG2B030L circuit breaker mounted within a panel?
This unit mount breaker can be installed using standard screw mounting or snapped directly onto a DIN rail. This dual mounting capability makes it highly adaptable for industrial control panels and custom Siemens enclosures.
What are the acceptable wire sizes for the terminals on this 30A breaker?
The feed-thru lugs accept 14 AWG to 10 AWG wire. Both copper (Cu) and aluminum (Al) conductors are permitted, provided they are sized appropriately for the 30 amp load and application requirements.
Is the HGG2B030L suitable for direct current (DC) applications?
Yes, in addition to its standard AC ratings, this breaker is rated for use in DC circuits up to 250VDC. It provides a 30kA interrupting rating for these DC applications.
What type of protection is provided by the fixed thermal magnetic trip unit?
The breaker utilizes an LI trip function, meaning it provides Long-Time (thermal) protection against sustained overloads and Instantaneous (magnetic) protection against short circuits. Both the thermal and magnetic trip points are fixed and non-adjustable.
Which breaker family and frame group does the HGG2B030L belong to?
It is part of the Siemens SENTRON family and falls under the GB/GG frame group. This is important to note when selecting compatible accessories, handle mechanisms, or enclosure mounting hardware designed specifically for GG frame breakers.
