That 160 A holds at every temperature point in that band, so you don't have to oversize for a hot enclosure. The breaker's breaking capacity hits 330 kA at 240 V, 242 kA at 415 V, and still delivers 187 kA at 500 V, with a steep drop to 3.7 kA at 690 V.
The minimum continuous current it can protect down to is 1.5 A, so it covers small subfeeds as well as the main. Insulation voltage is rated at 800 V, which gives headroom for 690 V systems. Power loss maxes out at 25.5 W — worth accounting for in a sealed enclosure if you're stacking multiple breakers. It includes a communication function, which means it can talk to a monitoring system for remote trip indication or load data.
