APPLICATION
1.R60M Earth leakage circuit breaker(elcb) is suiable to the circuit of AC50/60Hz,rated voltage 230V for 2pole and 400V for 4pole,and rated current 63A.When people come across the eletric shock or the leakage current of the electrical network exceeds the fixed value,this product can cut off the fault current in a second so to protect person and the equipments.It also can be used in the infrequent starting of the circuit and motors.This circuit breaker is suitable to industry,commerce,high-rise building,household and other kinds of places.This product conforms to IEC1008-1.It has the following characteristics:
2.Do not need any auxiliary power,having overcame the shortage of the electronic product(the Anti-jamming is not satisfying,easily be affected by the voltage of the ecectrical network and the lose of the protective for the cutting of the neutral axis),and then enlarge the protective range of the residual current;Rated conditional current can reach 4.5KA;Reliability will still be the same in the polluted environments;The enclosure and the parts all are adopted the with imported plastic materials which is high fire-resistant,heat-resistant and shookproof.Size is modulated with easily installed;Dynamic test installation,which makes the button more nimble and reliable.
