Application
It is divided into four types, Type C(basic type),Type L (standard type),Type M (high breaking capacity type ),and Type H (higher breaking capacity type). It has characteristics of small size,high breaking capa city,short arcin g,resist to vibratio n,and so on,which is an ideal product for the use on land and in ship, It is applied in the line of AC 50Hz,voltage 660V or below, rated insula ting voltage up to 800V(for HUM1-63,it s500V),and it
infrequent changeover and infrequent start of motor. Circuit breaker has overload,short-circuit and under- which can protect the line and power supply equip There are two kinds of installation, vertical installati horizontal installation(transverse insatallation). It accords with IEC 60947-2 standard.
