Product FAQs
7 answersHow is the Siemens HGG1B030L circuit breaker mounted?
The HGG1B030L is a unit-mount breaker that can be independently mounted on a standard DIN rail or secured to a base panel using mounting screws. It does not require additional adapters for DIN rail installation.
What types of applications is the HGG1B030L designed for?
This 1-pole breaker is designed for use in industrial control panels, OEM equipment, and compatible Siemens enclosures. It is a unit-mount breaker and is not intended for standard residential plug-on or bolt-on load centers.
Can the Siemens HGG1B030L be used in DC control circuits?
Yes, this breaker is rated for up to 125VDC with an interrupting capacity of 30kA, making it suitable for specific direct current industrial control applications.
What wire gauge is accepted by the lugs on the HGG1B030L?
The factory-installed feed-thru lugs accept wire sizes from 14 AWG to 10 AWG. Ensure terminals are torqued to the manufacturer specifications during installation.
Is the HGG1B030L rated for 347V commercial lighting circuits?
Yes, it is rated for 347VAC applications with an interrupting rating of 14kA, which is commonly used in commercial and industrial lighting systems.
Does the HGG1B030L feature a trip-free mechanism?
Yes, the HGG frame utilizes an overcenter toggle mechanism that is trip-free. If a short circuit or overload occurs, the contacts will force apart and the breaker cannot be held closed by the handle.
What frame family does the HGG1B030L belong to?
It belongs to the Siemens Sentron G-Frame family, specifically the GG frame. This compact industrial design is globally rated and shares field-installable accessories with other G-frame breakers.
