Product FAQs
6 answersWhat does the "SA" suffix indicate on the HDA36125SA?
The "SA" suffix means this breaker includes a factory-installed 120VAC shunt trip (equivalent to accessory S29386). This allows the breaker to be opened remotely using a control voltage signal.
What type of panelboard is required for the HDA36125SA?
This breaker requires a Square D I-Line panelboard or switchboard. It features a plug-in I-Line mounting bracket on the line side and mechanical lugs on the load side.
Are the trip settings adjustable on this PowerPacT H-frame breaker?
No. The HDA36125SA uses a traditional thermal-magnetic trip unit with fixed thermal overload and fixed magnetic short-circuit settings. The magnetic trip is factory set with a 900A hold and 1700A trip threshold.
What wire sizes are compatible with the standard lugs on this breaker?
The factory-installed mechanical lugs accept wire gauges from 14 AWG up to 3/0 AWG. They are rated for both aluminum and copper conductors.
Is the HDA36125SA rated for 100 percent continuous current?
No, this is a standard 80 percent rated circuit breaker. Per National Electrical Code (NEC) guidelines, continuous loads should not exceed 100 amps, which is 80 percent of its 125A nominal rating.
What does the "D" in the HDA36125SA part number represent?
The "D" designates the interrupting capacity tier within the PowerPacT H-frame family. It indicates a standard interrupting rating of 18 kA at 480 VAC and 25 kA at 240 VAC.
