Residual current circuit breakers/RCCBs/RCDs are of new design, has following specifications:

1. Standard: IEC 1008, GB16916, BS EN61008
2. Rated voltage(Un): 2P: 230V AC
4P: 400V AC
3. Rated current(In): 25, 63A
4. Rated residual operating current(IΔ N): 30, 100, 300, 500mA
5. Rated residual non-operating current(IΔ No): 0.51Δ N
6. Residual current off-time: ≤ 0.1s
7. Minimum value of rated making and breaking capacity(Im): 3KA
8. Rated conditional short- circuit current (Inc):
In=25, 40AInc=1500A
In=63 AInc=3000A
9. Eudurance:
Onload: 2000 cycles
Offload: 2000 cycles

All our RCCBs and other circuit breakers are made under strict ISO9001 systems, most already get CE approval.
