What wire sizes are compatible with the lugs on this XT1 60A breaker?
The factory-supplied line and load lugs accept copper or aluminum (Cu/Al) conductors ranging from 10 AWG to 2/0 AWG.
Which panelboards are designed to accept the XT1NU3060AYD000XXX circuit breaker?
This unit mount molded case circuit breaker is engineered specifically for installation in ABB ReliaGear NeXT Panelboards.
Does this breaker feature an adjustable or fixed trip unit?

The XT1 frame supports a variety of modular add-ons, including shunt trips, auxiliary contacts, undervoltage releases, mechanical interlocks, and padlock attachments.
What does the LI trip function code on this 60A breaker signify?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) protection for sustained electrical overloads and Instantaneous (I) protection for sudden short-circuit events, ensuring reliable equipment defense.
