That 160 A holds steady at every temperature step in the spec, so you size the bus and downstream gear to a flat 160 A without thermal headroom padding. Communication function is built in, so this breaker can report status and accept remote trip commands over the SENTRON communication bus — no external module required for basic connectivity. At 240 V it interrupts 187 kA; at 415 V and 440 V it holds 121 kA; at 500 V it still manages 75.6 kA; at 690 V it drops to 3.7 kA. That 187 kA at 240 V is well above typical utility fault levels in North American 240/120 V split-phase or 240 V delta services — you have headroom for high-fault panels without cascading upstream fuses.
The 86 mm depth (3.39 in) means it clears shallow backpanel enclosures where deeper breakers would hit the gland plate. Power loss is 25.5 W maximum at rated current — account for that in enclosure thermal calculations, especially in sealed stainless-steel panels.
