The XT1NU3110AFD000XXX: The description string XT1N 125 TMF 110-1100 3P F F UL/CSA decodes as: XT1N frame rated 125 A continuous, TMF thermal-magnetic fixed trip unit with an adjustable magnetic pickup range of 110–1100 A (10× In), three poles, front-front terminal connections, and UL/CSA certification. The front-front terminal pattern means line and load connections both exit the front of the breaker, which simplifies bus-bar layout in panel assemblies where rear-access is restricted.
