Molded Case Circuit Breakers and Switches
Auxiliary Contacts, Signalling Unit for Type NZM10-...-NA
NHI standard auxiliary contact
Switching simultaneously with the main contacts. They can be typically used for
signalling, interlocking or switching auxiliary circuits such as a control circuit.
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 R-NZM10 remote control drive.
RHI trip-indicating auxiliary contact
Actuating independently of the normal ON and OFF operations of the device,
sswitching only when the device has tripped due to overcurrents or other tripping
causes such as those initiated by voltage trips.
Signalling block
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 - 230V, AC or DC
