VB12L-40 series RCBO mainly applies to the circuit of AC 50Hz, rated voltage 240V, rated current up to 40A. When electric shock occurs to human, leakage current or voltage in grid exceeds stipulated values, RCBO cuts off the fault power in a very short time to protect the safety of human and electrical equipments, it also owns the functions of overload and short circuit protection. In addition, it can switch on and off non frequently the electrical facilities and lighting circuit while the circuit works well.
Lighting and distribution system for industry and commerce system.
