Product FAQs
7 answersCan the Square D HDA36080 be used in legacy I-Line panelboards?
Yes. Schneider Electric has evaluated older I-Line panelboards and switchboards, confirming that modern PowerPacT H-Frame circuit breakers like the HDA36080 are backward compatible and can be installed in existing distribution equipment without modification.
What is the difference between the HDA36080 and HGA36080 circuit breakers?
The primary difference is the maximum interrupting rating. The HDA36080 features a D-tier rating of 18kA at 480VAC, while the HGA36080 has a G-tier rating of 35kA at 480VAC. Their physical footprint, frame size, and mounting methods are identical.
What does the D in the HDA36080 catalog number represent?
The letter D designates the interrupting capacity level within the Square D PowerPacT series. For this specific model, it indicates a maximum interrupting rating of 18 kA at 480VAC, 25 kA at 240VAC, and 14 kA at 600VAC.
Can the HDA36080 replace an older FA or FH series I-Line circuit breaker?
Yes. The PowerPacT H-Frame series is the modern factory replacement for obsolete Square D F-Frame I-Line breakers. The HDA36080 will plug into the same bus space in an existing panelboard as the older FA and FH legacy models.
Is the HDA36080 rated for DC applications?
Yes. In addition to its standard AC ratings, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 20 kA, making it suitable for direct current power distribution.
How does the HDA36080 make its electrical connections?
It uses a plug-on I-Line connection for the line side, which snaps directly onto the panelboard bus assembly. The load side features standard mechanical lugs that accept 14 AWG to 3/0 AWG copper or aluminum conductors.
What protection is provided by the LI trip function on this breaker?
This unit features fixed long-time (L) and instantaneous (I) trip functions. The long-time element provides thermal protection against sustained overloads, while the magnetic instantaneous element clears short-circuit faults immediately.
