APPLICATION:
The residual current circuit breaker type FIN is in conformity
with the standards of VDE 0664,IEC1008 and BS 4293.
It can cut off the fault circuit immediately on the occasion
of shock hazard or earth leakage of trunk line.Thus it is suitable
to avoid the shock hazard and fire caused by earth leakage.
FIN ELCB is mainly suitable for use in variesties of plants
and enterprises, building,construction,commerce,guesthouses
and families.It can be used in circuits up to single phase 240V,three
phases 415V,50 to 60Hz. |
