Product FAQs
7 answersWhat wire sizes are accepted by the standard lugs on the XT1HU3080AFD000XXX?
The factory installed lugs on this XT1 breaker accept copper or aluminum wire sizes ranging from 10 AWG up to 2/0 AWG.
Which panelboards are compatible with the XT1HU3080AFD000XXX?
This unit mount breaker is designed for installation in ABB SACE Tmax XT panelboards and compatible switchboards. It requires standard hardware for fixed mounting rather than a plug-in or drawout base.
Is the XT1HU3080AFD000XXX rated for direct current (DC) systems?
Yes. Because it utilizes a thermal magnetic trip unit, it is fully rated for DC applications. It provides an interrupting capacity of 50kA at both 250VDC and 500VDC.
Can the thermal or magnetic trip settings be adjusted on this model?
No. This specific XT1 breaker features a fixed thermal and fixed magnetic (LI) trip unit. Both the long time overload and instantaneous short circuit pickup levels are factory set and cannot be modified in the field.
What does the "H" designation indicate in the XT1HU3080AFD000XXX part number?
The "H" indicates a High interrupting rating class for the ABB XT1 frame. For this specific model, it provides a 65kA interrupting capacity at 480VAC.
Can the XT1HU3080AFD000XXX be reverse fed?
Yes. Power can be supplied from either the top or the bottom terminals of this XT1 breaker up to its maximum voltage rating without impacting its protective functions.
Is this 80A XT1 breaker HACR rated?
Yes. Like most ABB SACE Tmax XT molded case circuit breakers, this unit is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment branch circuits.
