What this breaker delivers for the line-side spec
The TM210 thermal-magnetic trip unit gives fixed overload protection at Ir = 160 A and fixed short-circuit pickup at Ii = 10 × In (1600 A). No adjustment knobs; what you order is what protects the feeder.
The 3-pole form factor fits a 3-module wide cutout in a typical IEC distribution board. The nut keeper kit (included per the ZD00 suffix) retains the line/load lug nuts during vibration — a detail that matters if this breaker rides a machine skid or a mobile substation. No auxiliary contacts or shunt trip are built in; those snap onto the left side as separate accessories.
