Product FAQs
9 answersWhich panelboards are compatible with the HGA36090?
This PowerPacT H-Frame breaker is designed exclusively for Square D I-Line panelboards and switchboards. The line side features I-Line jaws that plug directly onto the panel bus to provide a secure electrical and mechanical connection.
Can the HGA36090 replace older discontinued circuit breakers?
Yes, this 90-amp I-Line breaker is a direct drop-in replacement for obsolete Square D F-Frame breakers, including the FA36090 and FH36090. It occupies the exact same mounting space on the I-Line busbar.
What does the G in the HGA36090 part number indicate?
The letter G designates the interrupting rating tier within the PowerPacT H-Frame family. It signifies a maximum short-circuit interrupting capacity of 65 kA at 240VAC, 35 kA at 480VAC, and 18 kA at 600VAC.
Is the magnetic trip setting adjustable on the HGA36090?
Yes. While the thermal overload trip is fixed at 90 amps, the instantaneous magnetic trip threshold is adjustable. This allows panel builders and electricians to precisely coordinate the breaker with other protective devices in the distribution system.
What wire size is accepted by the load lugs on the HGA36090?
The standard factory-installed load lugs (part number AL150HD) accept aluminum or copper conductors ranging from 14 AWG up to 3/0 AWG.
What tool and torque specifications are required for the load lugs?
The standard load lugs require a 3/16-inch Allen wrench. According to manufacturer specifications, they must be torqued to 50 in-lbs for 14 to 10 AWG wire, and 120 in-lbs for 8 to 3/0 AWG conductors. Always verify torque values on the breaker label prior to installation.
How is the line side of the HGA36090 connected?
The breaker features standard ABC phase sequencing with I-Line jaws on the line side. These jaws plug directly onto the phase bus of a compatible Square D switchboard, requiring no external wire connections or fasteners on the line side.
What mechanism is used in the HGA36090 to clear faults quickly?
This PowerPacT H-Frame breaker utilizes dual-break rotating contacts. During a severe short-circuit fault, this design creates rapid magnetic repulsion to extinguish the arc and clear the fault quickly, which reduces peak let-through current to protect downstream equipment.
Does the HGA36090 have a push-to-trip feature?
Yes, it includes an integral push-to-trip button on the front cover. This allows you to manually trip the breaker to verify that the internal operating mechanism is functioning correctly during routine panel maintenance.
