10.10 Temperature rise
The panel builder is responsible for the temperature rise calculation. Eaton will provide heat dissipation data for the devices.
10.11 Short-circuit rating
Is the panel builder's responsibility. The specifications for the switchgear must be observed.
10.12 Electromagnetic compatibility
Is the panel builder's responsibility. The specifications for the switchgear must be observed.
10.13 Mechanical function
The device meets the requirements, provided the information in the instruction leaflet (IL) is observed.
10.2.2 Corrosion resistance
Meets the product standard's requirements.
10.2.3.1 Verification of thermal stability of enclosures
Meets the product standard's requirements.

Special features
  • For interlock circuits, load-shedding circuits, make-before-break interruption of shunt trip for primary breaker use
  • Instantaneous shut-off NZM breaker at control voltage below 35-70% Us
  • For emergency-stop devices with an emergency-stop button
  • For breaker's signalizing commands/different states
  • 2 relays/unit
  • Trip unit config of activation criteria
  • Config by communication/breaker display/front USB port/Eaton Power Xpert Protection Manager
  • Switched off under-voltage trip: accidental contact with breaker’s primary contacts is prevented when switched on
  • Auxiliary contact make-before-break activation when manual switching on and off: ~20 ms(NZM2/3)/90 ms(NZM4)
