The ABB XT1NU3040AAA1A0XXX is a 3-pole molded case circuit breaker from the XT1N 125 frame family, equipped with a TMF (thermal-magnetic fixed) trip unit. This is the core overcurrent protection device for a distribution or motor branch circuit, sized for the XT1 frame's 125 A continuous rating at 40 °C.
The 3-pole configuration suits three-phase distribution panels, motor control centers, and feeder circuits.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The 3-pole construction means it switches and protects all three phases of a three-phase circuit, which is the standard configuration for 3-phase distribution and motor branch protection.
