ACCL is used for efficient distribution of Three Phase generator power in Residential Apartments , commercial complex , townships etc without overloading the generator. The ACCL will switch the load to generator supply during mains failure. It also acts as a current limiter when load on generator exceeds the pre-set limit the ACCL goes into an Overload Trip cycle mode alerting users through LED indication / Beep to reduce any excess load connected to the circuit.
