It's rated for distribution duty in commercial and industrial panels, built to EN/IEC 60947-2.
Breaking capacity drops as voltage climbs: 85 kA Icu at 240 V AC, 36 kA at 415 V, 25 kA at 500 V, and 8 kA at 690 V. The NSX100F sits below the NSX160F and NSX250F in the same ComPacT family; stepping up to those buys higher ampacity without changing the footprint.
Front connections top and bottom, 35 mm connection pitch. The 4-pole body is 140 mm wide, 161 mm high, 86 mm deep. IP40 enclosure protection, IK07 impact rating.
Mechanical endurance is 50,000 cycles; electrical endurance at rated current and 440 V is 30,000 cycles — that's a solid duty cycle for a distribution breaker that isn't switched daily.
