Product FAQs
6 answersWhat does the "SA" suffix indicate on the HDL36125SA catalog number?
The "SA" suffix means this breaker includes a factory-installed 120VAC (110-130VAC) shunt trip. This allows the breaker to be tripped remotely by applying a control voltage signal.
Do I need to purchase lugs separately for the HDL36125SA?
No, this breaker comes with factory-installed lugs that accept 14 AWG to 3/0 AWG aluminum or copper wire.
Which breaker frame family does the HDL36125SA belong to?
It is part of the Square D PowerPacT H-Frame family. It is commonly used in industrial control panels, switchboards, and industrial enclosures.
What does the LI trip function code mean on this breaker?
The LI code indicates the thermal-magnetic trip unit provides Long-Time (overload) and Instantaneous (short circuit) protection. Both the thermal and magnetic trip points are fixed on this specific model.
Is this breaker suitable for DC control panels?
Yes, the HDL36125SA is rated for use in DC systems up to 250VDC, providing a 20 kA interrupting capacity for those applications.
What does unit mount mean for the HDL36125SA?
Unit mount means the breaker is designed to be bolted directly to a backpan or mounting surface in a control panel or enclosure, rather than plugging into an I-Line busbar system.
