It carries UL/CSA certification for North American panel installations. The TMF trip unit provides adjustable thermal and fixed magnetic protection, sized for motor and feeder circuits where the continuous current rating lands within the 90–900 A adjustable range. ## Trip unit and application fit The TMF 90-900 trip unit adjusts from 90 A to 900 A. One frame covers multiple motor sizes or feeder taps without swapping the device. ## Installation note Fixed mounting and fixed terminals — no plug-in base or draw-out cradle. The breaker lands directly on the bus bars or panel-mounting plate. Torque the line and load terminals to the values stamped on the breaker nameplate; the UL/CSA listing depends on that. The 3-pole unit occupies three adjacent module spaces in a standard panelboard.","metaTitle":"ABB XT1SU3090AYD000XXX Molded Case Circuit Breaker, TMF 90-900","metaDescription":"ABB NEXT1S 125 series MCCB, order code XT1SU3090AYD000XXX.
