Product FAQs
6 answersWhat panels and enclosures are compatible with the ABB XT7HU380CEFF000XXX?
This molded case circuit breaker is designed for installation in ABB ReliaGear neXT Panelboards, ABB ReliaGear Switchboards, and ABB SACE Tmax XT7 Enclosures.
How are the trip parameters configured on this breaker?
This model features an Ekip Dip LSI electronic trip unit. The Long-Time, Short-Time, and Instantaneous trip functions are manually configured using DIP switches located on the front of the breaker to ensure precise system coordination.
Does the XT7HU380CEFF000XXX provide integral equipment ground fault protection?
No, this specific configuration includes an LSI trip unit. It provides comprehensive overload and short-circuit protection but lacks the Ground (G) fault protection function, which would require an LSIG trip unit.
Can this 3-pole Tmax XT7 breaker be wired for single-phase systems?
Yes, ABB XT7 3-pole circuit breakers are suitable for single-phase applications up to 600VAC, provided they are wired according to factory guidelines and UL standards.
What do the letters CE and FF denote in the XT7HU380CEFF000XXX catalog number?
In ABB nomenclature, CE signifies that the breaker is equipped with an Ekip Dip LSI electronic trip unit. The FF designates that it is a fixed breaker outfitted with front terminals for both the line and load connections.
What is the ambient operating temperature range for this circuit breaker?
Tmax XT circuit breakers operate safely in ambient air temperatures ranging from -25 to +70 degrees Celsius. Note that the reference temperature for the electronic trip unit is +40 degrees Celsius, and operating near the maximum limits may require cable derating.
