Product details

The Siemens 3RV2021-1BA10-0DA0 is a SIRIUS 3RV2 motor starter protector in size S0, designed for system protection without phase failure protection. It carries an A-release rated 1.4...2 A and a short-circuit release set at 26 A, with screw terminals and standard switching capacity.

The A-release range of 1.4...2 A sets the thermal overload pickup — this protector is sized for motor full-load currents in that band. The 26 A short-circuit release handles magnetic trips on fault, clearing before upstream devices need to act.

RoHS compliance is documented since 01-10-09, and REACH candidate-list information is available per Article 33.
