Types
Both RCCBs and RCBOs are further divided into types depending on the operating function:
1.Type AC :For which tripping is ensured for residual sinusoidal alternating currents, whether suddenly applied or slowly rising.
2.Type A ： For which tripping is ensured for residual sinusoidal alternating currents and residual pulsating direct currents, whether suddenly applied or slowly rising
3.Type S ：For selectivity, with time-relay.
Tripping Sensitivity Data
1. Rated residual current max. 30 mA for personnel, material and fire protection, as well as protection against direct contact.
2. Rated residual current max. 300 mA for preventive fire protection in case of insulation fault
3. The rated residual current is 100mA, cooperate with the earth system, according to the formula lAn<50/R, provide indirect contact protection again
4. Rated residual current of 10 mA is mainly used in areas that pose an increased risk to personnel.
The total Residual Circuit Breaker in the distribution box should be selected according to the capacity of this power supply, rather than the sum of several loads. The load is changing, and if the load increases in the future, the main switch will also be changed, so each shunt switch protects its own shunt, and the current of the main switch should be determined according to the transformer current or the rated current of the cable.
If you choose a switch, the general household main switch is 32A, and the one with larger power consumption is 64A. The larger household vertical air conditioner is only 4-5KW, and it is one vertical and three wall-mounted.
