Product overview
ID residual-current circuit breakers disconnect an AC circuit on earth-leakage current. They do not provide overload or short-circuit overcurrent protection.
Technical selection summary
| Rated currents | 16, 20, 25, 40, 50, 63A |
|---|---|
| Residual-current sensitivity | 30, 100, 300, 500mA; operating range 0.5–1 times rated residual operating current |
| Voltage / poles | 2P: AC230/240V; 4P: AC400/415V; 50/60Hz |
| Residual-current type | Type AC, indicated by the sinusoidal symbol on the original nameplate; not for DC residual-current applications |
| Conditional short-circuit rating | The pictured 40A/4P/30mA unit marks Inc = IΔc = 6kA with SCPD fuse 100A; Im = 500A. This is not a standalone Icu breaking rating for an overcurrent breaker |
| Operating time / enclosure | Original table: ≤0.3s; IP20; endurance 4,000 operations |
| Connection | Retain neutral and terminal numbering shown on the exact device; use a coordinated upstream short-circuit protective device |
Specify poles, rated current, residual-current sensitivity and supply. Match upstream fuse/breaker coordination to the actual delivered RCCB.
Typical applications
- AC distribution circuits requiring earth-leakage protection
- Building and industrial panels with separate overload and short-circuit protection
