Product FAQs
7 answersWhat type of panelboards is the HGA260404 compatible with?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on I-Line connection on the line side and mechanical lugs on the load side.
What does the G in the HGA260404 part number indicate?
The G designates the interrupting capacity tier within the PowerPacT H-Frame series. For this model, it signifies a rating of 65kA at 240V AC, 35kA at 480V AC, and 18kA at 600V AC.
Which legacy Square D breakers does the HGA260404 replace?
This PowerPacT H-Frame breaker serves as a modern replacement for obsolete 40A, 2-pole F-Frame I-Line breakers, including the FA26040 and FH26040 series.
How is the HGA260404 installed into the panel?
It utilizes an I-Line style plug-in connection. The breaker snaps directly onto the panelboard bus on the line side, while the load side uses traditional mechanical lugs for wire termination.
What wire sizes are accepted by the load side lugs on this breaker?
The mechanical lugs on the load side accept 14 AWG to 3/0 AWG aluminum or copper wire. Because this is an I-Line breaker, the line side connects directly to the bus and does not require wire termination.
Is the HGA260404 HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment.
Does this breaker include a push-to-trip feature?
Yes, PowerPacT H-Frame circuit breakers feature an integral push-to-trip button on the cover. This allows you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
