The Square D HDL36070SA is a 3-pole, 70A MCCB from the PowerPacT H-Frame family. Built for commercial and industrial applications, it provides reliable thermal-magnetic protection. This unit-mount breaker installs into standard switchboards and control panels using included lugs. It serves as an exact replacement for discontinued FAL36070 units. Rated for 18 kAIC at 480V, it features a factory-installed 110/130Vac shunt trip (SA suffix) for remote actuation and a Visi-Trip indicator.Specifications

Product FAQs
6 answersWhat does the "SA" suffix mean in the HDL36070SA part number?
The "SA" suffix indicates that this breaker includes a factory-installed 120VAC shunt trip, allowing the breaker to be tripped remotely.
What does "Unit Mount" mean for the HDL36070SA?
Unit mount means this breaker is designed to be bolted directly to a backpan or mounting surface and features mechanical lugs on both the line and load sides for wire connections, rather than plugging into a busbar system like an I-Line breaker.
What are the magnetic trip settings for the HDL36070SA?
This breaker features a fixed magnetic trip unit with an 800A hold current and a 1450A trip current.
Can I field-install a different shunt trip voltage in the HDL36070SA?
The HDL36070SA comes with a factory-installed 120VAC shunt trip. If a different control voltage is required, the internal accessory can be replaced in the field with a compatible PowerPacT H-Frame shunt trip module.
How do I manually test the trip mechanism on the HDL36070SA?
This breaker features an integral push-to-trip button on the front cover, allowing you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
How does the HDL36070SA limit peak current during a fault?
This breaker is equipped with dual-break rotating contacts that open quickly during a short circuit, reducing the amount of peak current and let-through energy to protect downstream equipment.
