Product FAQs
6 answersWhat enclosures or panels accept the HGL36125 breaker?
This unit mount breaker is designed for installation in industrial control panels, standard switchboards, and Square D PowerPacT H-Frame enclosures. Because it uses a feed-thru lug connection, it bolts directly to a backpan and is not compatible with I-Line plug-on panelboards.
What does the L in the HGL part number indicate?
The L termination code means the breaker comes with factory installed lugs on both the line and load sides. This indicates it is a unit mount breaker designed for hardwiring, rather than a plug-on or drawout style.
What is the difference between an HGL36125 and an HGA36125?
The HGL is a unit mount breaker equipped with standard lugs on both ends for wiring directly to a backplate. In contrast, the HGA is an I-Line breaker built with a plug-on connection specifically for Square D I-Line distribution panels.
Can the HGL36125 circuit breaker be reverse fed?
Yes, this thermal magnetic H-Frame breaker is suitable for reverse connection. You can safely supply incoming power to either the top or bottom lugs without affecting its overcurrent protection capabilities.
How can I manually test the tripping mechanism on this breaker?
The HGL36125 features an integral push-to-trip button located on the front cover. This allows you to safely and easily test the mechanical tripping operation of the breaker during maintenance.
What internal mechanism does the PowerPacT H-Frame use to limit fault currents?
This breaker series utilizes dual-break rotating contacts. This specific design helps reduce the peak current and limits the let-through energy during a short circuit fault condition, providing enhanced equipment protection.
