This simplifies ordering but locks the protection curve; verify the load's full-load amps match 125 A before committing the BOM line. ## Sourcing posture Because the lifecycle stage is current, this part is sourced through standard ABB distribution. No surplus or broker channel is needed for this order code.","metaTitle":"ABB XT1NU4030AFF000XXX XT1N 125 TMF MCCB, current lifecycle","metaDescription":"ABB XT1NU4030AFF000XXX XT1N 125 TMF molded case circuit breaker.
