B-curve trips between 3–5× rated current (9–15 A magnetic release), so it handles resistive and general-purpose loads without nuisance tripping on mild inrush. The 3 A rating suits lighting strings, control transformers, or small signal circuits where overcurrent protection needs a tight thermal band. Single-pole format clips onto standard DIN rail in a distribution board. The 1-module width leaves room for adjacent poles or RCDs in the same row.
RoHS compliant since 01-06-13. Product class B means return restricted. Active lifecycle status confirms ongoing production.
