Which type of fuse is recommended for protection of ATV28

Published date: 31 October 2018

 

Issue:   Which type of fuse is recommended  for protection of ATV28
 
Product Line:   ATV28
 
Environment:  All
 
Cause:   Fuse recommendation 
 
Resolution:   
There is no fuses list recommend for the ATV28 because it do not bring advantage compares to the breaker.
Indeed, if there is a short-circuit on motor side, the ATV58 protects itself, if there is a short-circuit in the drive even if you protect the diodes bridge with some fuses, the drive is, anyway, in serious breakdown.
A breaker is sufficient to avoid too much internal damages. If you want to change the breaker by fuses, their tripping curve need to be close to the breaker recommend in the catalogue.
