gpnv series small leakage circuit breaker-ag凯发k8国际
the characteristics of:◎overload protection ◎electric leakage protection ◎the contact between providing personal protection ◎for the insulation of the electrical equipment fault protection
◎provide supplementary habeas corpus for direct contact ◎use instructions window ◎no positive flat-fell seam
◎breaking phase line and neutral wire at the same time,phase line (p) with protection,neutral (n) with no protection and the points after first
◎electronic leakage protection filter unit:can prevent transient overvoltage(interference lines such as lighting and other equipment)and instantaneous overcurrent(such as large capacitive load circuit)the misoperation caused by tripping
