Its E tripping characteristic — a curve designed for selective coordination with upstream fuses or breakers — means it tolerates short inrush currents without nuisance tripping, useful in meter-cabinet or distribution-board applications where selectivity matters. Rated breaking capacity is 25 kA per EN 60898, sufficient for high-fault installations. The 3-pole design (3P) handles three-phase feeds, and the unit mounts on a 40-mm busbar system per DIN 43870 Part 2 — standard for European meter panels.
Switch position indicator shows OFF = green, ON = red for quick visual status.
Shock resistance is 30 g (11 ms duration, 3 impacts), and vibration resistance per IEC 60068-2-6 is 2 g over 5–150 Hz. The unit is sealable via locking slide with lock, wire seal, cable ties, or Antilux — important for utility-metering applications where tamper evidence is required.
