Product FAQs
8 answersWhat does the "SA" suffix in the HDL36020SA catalog number indicate?
The "SA" suffix indicates that this circuit breaker includes a factory-installed shunt trip accessory. For PowerPacT H-frame breakers, the SA suffix corresponds to a shunt trip with a control voltage of 110 to 130VAC or 125VDC, allowing the breaker to be tripped remotely.
What is the difference between the HDL36020SA and the HDA36020SA?
The HDL36020SA is a unit-mount circuit breaker with factory-installed lugs on both the line and load sides, designed for cable-in and cable-out installations. The HDA36020SA is an I-Line breaker that features a plug-on connection on the line side to mount directly onto an I-Line panelboard busbar.
Are the lugs on the HDL36020SA rated for both copper and aluminum wire?
Yes, the factory-installed lugs on this PowerPacT H-frame breaker are dual-rated for both aluminum and copper conductors (AL/CU) ranging from 14 AWG to 3/0 AWG.
What enclosures or panels is the HDL36020SA compatible with?
As a unit-mount, feed-thru breaker, the HDL36020SA is designed for use in Square D industrial enclosures, switchboards, and motor control centers that accept unit-mount H-frame breakers. It cannot be plugged into I-Line panelboards.
Is the trip unit on the HDL36020SA adjustable?
No, this breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions. It does not have adjustable trip settings like those found on electronic Micrologic trip units.
Is the HDL36020SA suitable for use with heating, air conditioning, and refrigeration equipment?
Yes, this PowerPacT H-frame circuit breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration motor circuits.
Is the HDL36020SA rated for 80 percent or 100 percent continuous current?
This breaker is standard 80 percent rated, meaning continuous loads should not exceed 80 percent of its 20-amp rating. For a 100 percent rated version, the catalog number would typically include a "C" suffix.
Can the HDL36020SA be reverse fed?
Yes, because it features a standard thermal-magnetic trip unit, the HDL36020SA is suitable for reverse feeding. This allows the line and load connections to be swapped if required by the installation layout.
