Product description：
RDL8-40 residual current circuit breaker with over-current protection is applicable to a circuit of AC50/60Hz, 230V (single phase), for overload, short circuit and residual current protection.
Electromagnetic type RCD.
Rated current up to 40A. It is mainly used in domestic installation, as well as in commercial and industrial electrical distribution systems.It conforms with the standard of IEC/ EN61009.
Main features：
1. Supports all types of residual current protection: AC, A
2. Multiple breaking capacities for residential and industrial applications
3. Rated current up to 40A with user-defined poles for single-phase or three-phase grids
4. Rated residual current: 30mA, 100mA, 300mA
The role of RCBO：
Residual current operated circuit breakers (RCBO) with overcurrent protection are mainly suitable for applications requiring both overcurrent protection (overload and short circuit) and earth fault current protection. It can detect faults and trip in time to ensure the safety of staff and equipment.
