CBI TQA Crcuit Breaker

TQA Hydraulicmcb(circuit breaker,miniature circuit breaker) is mainly for suitable for overload and short circuit protection. It adopt hydraulic magnetic trip instead bimetal .So it has a high sensitivity and it is also not effected by the ambient temperature . It is especially used for illumination and distribution in industry and commerce. They are mainly used for overload and short-circuit protection within the circuit of AC 50Hz/60Hz, rated voltage of single pole or double up to 240V, three poles up to 415V. They can also be used for an unfrequent switch-over of the circuit and illumination under normal conditions. They are comply with IEC 157-1973, BC4752-1977 and BS 3871 part 1 Specification 1.number of poles :1P, 2P,3P 2.Rated current(A):6,10,16,20,25,30,40,50,63,70,80,90,100 3.Breaking capacity(A):3000 4.Rated voltage(V)110/220(1P), 240/415(2P),415(3P) 5.Rated frequency:50/60HZ 6lectrical life:no less than 6000 operation 7Mechanical life:(O-C)no less than16000 operation
