It carries a CLASS 10 trip characteristic, with an adjustable thermal overcurrent release set from 1.1 A to 1.6 A and a fixed magnetic short-circuit release at 21 A.
The 1.1–1.6 A thermal range fits small motors, pumps, or fans drawing around 0.75 kW at 400 V three-phase.
Screw terminals accept stranded or solid copper up to the rated cross-section — torque to the value marked on the housing. The auxiliary switch occupies the left-side slot and is wired separately from the main power circuit; verify the NO/NC assignment against the wiring diagram before energizing.
