SM6H earth leakage circuit breaker is used for  protection against electrical leakage, overload, shortcircuit, overvoltage in the circuit of 50/60Hz,rated voltage 230/400V, rated current up to 100A.When people come across the electric shock or the leakage current of the electrical network exceeds the fixed value, this product can cut off the fault current in one second so as to protect personal safety and prevent accident on equipments caused by residual current from happening, it also can be used to protect circuit against short circuit and overloading, and used for infrequent on-and-off switching operation under the normal circumstance. It is mainly applied in architectural  lighting and power distribution system protection.This product meet’s the standard of IEC/EN60947-2, IEC/EN61009-1.Maximum connecting ability of 35mm2,wiring torque 3.5N  m, applicable to a variety of installing equipments, wiring stronger.Protection class:IP20
