Product FAQs
6 answersHow is the HGP36040 breaker mounted in an electrical system?
This breaker features a unit-mount, or bolt-on, configuration. It secures directly to a backplate or mounting pan using screws, making it ideal for control panels and standalone enclosures rather than plug-on busbar systems.
Is this breaker compatible with Square D I-Line panelboards?
No. The HGP36040 is a unit-mount breaker. I-Line panelboards require breakers with specialized plug-on brackets, such as the HGA or HJA series.
What does the G in the HGP36040 catalog number indicate?
The G designates the interrupting rating tier within the PowerPacT H-frame series. This specific tier provides a maximum fault clearing capacity of 65kAIC at 240VAC and 35kAIC at 480VAC.
Can the HGP36040 be utilized in DC power applications?
Yes, the 500VDC rating allows this breaker to protect direct current circuits in addition to standard AC distribution systems.
What type of protection does the thermal-magnetic trip unit provide?
The thermal-magnetic mechanism offers dual protection. The thermal component responds to prolonged overloads with a long-time delay, while the magnetic component provides instantaneous tripping during severe short circuits.
Can this unit-mount breaker be installed on a DIN rail?
Yes, you can mount this breaker onto a standard DIN rail by adding the compatible Square D PowerPacT H-frame DIN rail mounting adapter accessory.
