- Series protects the human being from indirect contact, also protects from any potential fire hazard cause by long existing ground fault which can not be detected by over-current protector
- When other protective devices are out of order, this residual current circuit breaker whose rated residual operated current is 30mA will play a role of additional protector directly
- Technical parameters:
- Frame size rated current Inm (A): 100
- Rated current In(A): 16, 20, 25, 32, 40, 50, 63, 80, 100
- Class of rated ultimate short-circuit breaking capacity M, H
- Pole number (p): 3, 4
- 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
- Rated operating voltage Ui: 800V
- Rated impulse withstand voltage Uimp: 8000V
