Product FAQs
8 answersWhich Siemens panelboards are compatible with the HGG3B100L 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.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed lugs accept 8 to 1/0 AWG copper wire or 8 to 2/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation.
Can the HGG3B100L be utilized in direct current (DC) systems?
Yes, this thermal magnetic breaker is rated for DC applications up to 250VDC, providing an interrupting capacity of 14kAIC at that voltage.
Is the HGG3B100L a plug-in or bolt-on breaker?
It is a unit-mount, feed-thru circuit breaker. It does not plug onto a busbar but rather mounts directly to the chassis, DIN rail, or enclosure backpan and connects via cable lugs on both the line and load sides.
Are the trip settings adjustable on the HGG3B100L?
No, this breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without adjustable dials.
What is the direct replacement for the HGG3B100L?
The HGG frame is a legacy Sentron series being phased out by Siemens. The recommended successor is the 3VA51 series, specifically catalog number 3VA5110-5EC31-0AA0, though a panel retrofit kit may be required depending on your application.
What does the H in the HGG frame designation indicate?
In the Siemens Sentron GG frame family, the H indicates a high interrupting capacity. The HGG3B100L provides up to 65kAIC at 240V and 35kAIC at 480V, which is higher than standard NGG breakers.
Does the HGG3B100L feature a trip-free mechanism?
Yes, it utilizes an over-center toggle mechanism that is trip-free. This ensures the breaker contacts will open during a fault even if the handle is physically held in the ON position.
