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 casualty 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, which 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.
