The 3RV2011-0KA25-Z W96: The 0.9...1.25 A overload range means this unit protects small motors — fractional-horsepower pumps, fans, or conveyor drives — where the full-load current falls within that window. The S00 frame size snaps onto DIN rail and occupies about 45 mm of width, fitting compact control cabinets.
The product group code is 5332 and the group code is R711 — these are Siemens internal classification codes used for logistics and catalog sorting, not functional ratings. They confirm the part belongs to the motor protection / circuit breaker category in the Siemens data model.
