Description
Delivering 50 amps of continuous current capacity, the Siemens HGG3B050L is a 3-pole MCCB utilizing fixed thermal and magnetic trip elements for essential LI fault protection. This unit mount component integrates into DIN rails and Siemens enclosures. While it serves as a reliable replacement for existing Sentron GB/GG frame setups, it is superseded by the 3VA5150-5EC31-0AA0. Rated 35kAIC at 480V, it includes 3TC1GG20 lugs designed to accept heavier 8-1/0 AWG copper wiring.Specifications

Product FAQs
6 answersWhat wire sizes and materials are accepted by the terminal lugs on the HGG3B050L?
The factory-installed lugs accept 8 to 1/0 AWG copper (Cu) wire or 8 to 2/0 AWG aluminum (Al) wire. Ensure proper torque specifications are followed during installation to prevent arcing or thermal issues.
Where can the Siemens HGG3B050L breaker be installed?
This unit mount breaker is designed for use in Siemens enclosures, industrial control panels, and can be DIN rail mounted. It features a feed-thru connection type with lugs on both the line and load sides, rather than plugging into a standard load center bus.
Can the HGG3B050L be used in direct current (DC) applications?
Yes, this breaker is rated for DC applications up to 250VDC, providing an interrupting capacity of 14kAIC at that voltage. This makes it suitable for specific industrial control and battery systems.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the HGG3B050L features fixed thermal and fixed magnetic trip settings. It provides standard long-time and instantaneous (LI) protection without user-adjustable dials.
What does the 'H' in the HGG3B050L part number indicate?
The 'H' indicates that this is a high-interrupting version of the standard GG frame. It provides 35kAIC at 480VAC and 65kAIC at 240VAC, which is significantly higher than standard-tier breakers in the same physical footprint.
What frame family does the HGG3B050L belong to?
It is part of the Siemens SENTRON series, specifically falling under the HGG frame designation within the broader GB/GG frame group.
