On a 440 V insulated system the 10 kA Icn service breaking capacity handles the fault level typical of most commercial and light industrial sub-distribution boards; the 25 kA Icu ultimate capacity gives additional headroom for coordination studies.
The 35 mm width occupies one standard modular position, and the 69 mm depth leaves clearance for wiring in a typical 120 mm deep enclosure. The IP20 finger-safe front face suits enclosed distribution boards; the IP40 rating on the terminals means the breaker is protected against solid objects over 1 mm — adequate for clean, dry panel environments. Terminal tightening torque is 2.8 Nm max, compatible with a standard Pozidriv No. 2 bit.
The bi-directional cylinder-lift terminal design accepts both copper and aluminium conductors and allows loop-through wiring without separate busbar connectors — a time-saver on multi-pole assemblies.
