NHI STANDARD  AUXILIARY CONTACT

•  Switching simultaneously with the main contacts. They can be typically used for signaling, interlocking or switching auxiliary circuits such as a control circuit.

• Field Installable
  
   

VHI EARLY MAKE  AUXILIARY CONTACT

• Typically used for powering up the undervoltage trip prior to closing of main contacts and for control circuit interlocking tasks.

• CANNOT be used in conjunction with T-NZM10 remote control drive.

• Field Installable
  
   

RHI TRIP INDICATING AUXILIARY CONTACT

• Actuating independently of the normal ON and OFF operations of the device, switching only when the device has tripped due to overcurrents or other tripping causes such as those initiated by voltage trips.

• Field Installable
  
   

•  Differential fault indication and visual display of breaker operating states:
  
  -(1) + (2) tripping due to short circuit.
  
  -(2) tripping due to overload and general trip condition.
  
  -(3) overload early warning signal in the event that the long time response setting is about to be exceeded (i.e. useful for load shedding purposes).

• Each function signals via a pair of contacts (1 N.O. and 1 N.C.).

• Mounts directly onto lower portion of circuit breaker

• Required supply voltage: 24-230 V, AC or DC.

• Field Installable
