Description
Operating within commercial electrical systems, this 30A molded case circuit breaker supplies thermal-magnetic LI protection. It is manufactured with a BC phase connection to accommodate specific busbar layouts. The component mounts into Square D I-Line panelboards and switchboards, ensuring a secure fit. It acts as an exact cross-reference for the older FA26030BC catalog number. Capable of handling 25kAIC at 240VAC, the current-limiting breaker includes a visual trip indicator.Specifications

Product FAQs
7 answersWhat do the letters in the HDA260304 part number represent?
In the Square D PowerPacT series, "H" stands for the 150A maximum H-Frame size, "D" indicates the standard interrupting rating tier (18kA at 480VAC), and "A" specifies an I-Line plug-on connection for the line side with mechanical lugs on the load side.
What does the "4" at the end of the HDA260304 catalog number mean?
The "4" indicates that this 2-pole breaker is factory-configured for a B and C phase connection on the I-Line bus.
Can the HDA260304 replace older Square D FA series breakers?
Yes, the PowerPacT H-Frame HDA260304 is the direct modern replacement for the obsolete 2-pole, 30-amp FA26030 (specifically the FA26030BC if matching the BC phase connection). It fits the same I-Line panelboards and provides equivalent thermal-magnetic protection.
What is the recommended lug torque for the HDA260304 circuit breaker?
For the standard AL150HD mechanical lugs, which accept both aluminum and copper conductors, torque the wire binding screws to 50 lb-in for 14 to 10 AWG wire, and 120 lb-in for 8 to 3/0 AWG wire. A 3/16 inch Allen wrench is required for the lug screws.
Are the trip settings on the HDA260304 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. While it provides both long-time and instantaneous protection, the settings are factory-fixed with a magnetic hold current of 350A and a magnetic trip current of 750A.
Can I install the HDA260304 in a standard QO or Homeline load center?
No, this breaker features an I-Line style plug-in connection. It is designed exclusively for commercial and industrial Square D I-Line panelboards and switchboards, and will not fit residential QO or Homeline panels.
Is the HDA260304 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires group motor protection.
