10 KA according IEC 60947-2 and IEC 60947-4
Miniature Circuit Breakers (MCB) which can be used in low voltage electrical installations to protect conductors, switchgear, and electrical equipment in general against overload and short-circuit.
Product Description
Provides protection against Short-circuit/Overload current and function of isolation.
High breaking current withstand capacity
Applicable to terminal and pin/fork type busbar connection
Equipped with finger protected connection terminals
Fire resistant plastic parts endures abnormal heating and strong impact
Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity
Independent of power supply and line voltage, and free from external interference, voltage fluctuation
