  FIELD FAILURE RELAY
For D.C. Drives and Instrumentation.
 
     
Field Failure Relay
 
  • The Field Failure Relay, when used in series with the field circuit, ensures that no power is supplied to the Armature unless Field circuit is complete.
 
 
  • Field Failure Relay, also known as Field Loss Relay protects the D.C. Shunt motor or main circuit under open field conditions.
