The C-curve trip characteristic means it holds up to 5–10× rated current for short-duration inrush, then trips magnetically above that threshold; this suits mixed resistive-inductive loads like lighting banks, small motor starters, and control transformers where the inrush isn't extreme. It occupies one modular width (18 mm) on DIN rail, so it fits standard consumer units and sub-distribution panels without crowding.
The 76 mm depth plus 70 mm installation depth leaves clearance for wiring behind the panel door — standard for a 1-module MCB. Neutral conductor switching is built in, so no separate neutral bar is needed downstream for this pole. The sealable design allows a lock or tag to prevent unauthorized toggling — useful for safety isolation on a dedicated circuit.
