At 2 A, it protects a single-phase or three-phase load leg against overcurrent — sized for control transformers, small lighting circuits, or instrument loops where a standard 6 A or 10 A MCB would leave the wiring unprotected. The DIN-rail footprint snaps directly into a standard 35 mm top-hat rail inside an enclosure or panel, occupying a single module width.
No official successor order code exists — this is the current release, not a phase-out replacement.
Physical integration
The single-module width fits into the same slot as any standard 1P MCB, so panel fill factor is predictable.
