This ABB 1SDA068093R1 is a current-production XT4N 160 frame distribution circuit breaker, rated 16 A fixed (In) on a 160 A frame (Iu), with a TMD thermal-magnetic trip unit, 4 poles, and 690 V AC (50/60 Hz). The high frame-to-rating ratio means the same XT4 hardware can cover tripping up to 300 A by swapping the trip module—handy for stocking one frame size for multiple lower-current feeders in a mill panel. Keeps the machine running with minimal spare part variety.
4 poles, rated 690 V AC at 50/60 Hz.
