Detailed Product Description

The item is in accordance with standards of IEC.,   applying to the circuit of AC50/60Hz,

240V single phase, 415V three  phases and below it for industrial and mining enterprise,

trade building, commerce and family. To mainly prevent electric fire and personal
casual-
ty accident caused by personal electric shock or leakage of  electrified wire netting,

this ELCB is a current-operated, fast leakage protector of pure electromagnetic type,
wh-
ich can break  off  fault  circuit rapidly in order to avoid occurrence of accident.
The 
item is precise in structure, less elements, without auxiliary power and high   
working 
reliability. The function of the switch won`t be influenced by ambient temperature
and 
lightning. The mutual inductor of  the item is used  to test  vector differential
value 
of passing current, and  produces  a relevant  output  power and add it to the tripper
in
secondary winding, if the current  of  vector differential value of protected circuit
of 
personal electric shock is up to or over leakage operating current, the tripper will
act 
and cut off so that the item will take effect of protection.
