Product FAQs
6 answersWhich Siemens panelboards are compatible with the HGG2B070L breaker?
This unit mount breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as compatible Siemens switchboards and standalone enclosures.
How is the HGG2B070L physically mounted in an enclosure?
This is a unit mount, feed-thru circuit breaker. It can be secured using standard screw mounting or installed on a standard DIN rail, depending on your specific enclosure setup.
What wire sizes and materials are accepted by the lugs on this breaker?
The factory lugs accept 8 AWG to 1/0 AWG copper wire, or 8 AWG to 2/0 AWG aluminum wire. Always verify that your conductors match these ranges before terminating.
Can the HGG2B070L be utilized in direct current (DC) systems?
Yes, this thermal magnetic breaker is rated for DC applications up to 250VDC, providing a 30kA interrupting capacity for DC circuits.
What does the H in the HGG frame designation indicate?
The H denotes a high interrupting capacity version of the standard GG frame breaker. It provides elevated fault protection, such as 65kA at 240VAC and 35kA at 480VAC, compared to standard-tier breakers.
Are the thermal and magnetic trip settings adjustable on this model?
No, the HGG2B070L features fixed thermal and fixed magnetic trip elements. If your application requires adjustable trip curves, you will need to select a breaker equipped with an electronic trip unit.
