- Rated ultimate short-circuit breaking capacity Icu: AC400, 50, 85kA
- Rated service short-circuit breaking capacity Ics: AC400, 35, 50kA
- Rated residual operated current IΔn: 100, 300, 500mA
- Ultimate non-driving time Δt(s): 0.1/0.5/1 (test current 2IΔn)
- Rated residual non-operated current (mA): IΔnx 50%
- Rated residual short-circuit making capacity IΔm: Icu x25%
- Rated operating voltage Ue: 400V AC
