Ambient air temperature
The ambient air temperature is about +40 ºC; the ambient air temperature is below -5ºC; the average value of ambient air temperature 24h is not more than +35ºC.
Elevation: installation elevation of not more than 2000m.
Atmospheric condition:
Relative humidity of the atmosphere in the surrounding air temperature of +40ºC is less than 50%; the relative humidity at the lower temperature can be high; most of the wet month average maximum relative humidity of 90%, the monthly average minimum temperature of +25ºC and considering the temperature due to changes in product surface.
Pollution grade: grade 3.

Note:
1. The N-pole breaker has no protection which closing and opening with the other three poles. 2. The type of thermal magnetic for NS-400/630 has no four poles.
1. Overload protection with adjustable threshold, as defined by IEC60947-4 (2) tripping class 10A,10 and 20
2. Short-circuit protection with adjustable threshold (6...13xIr)
3. Phase failure protection (built-in electronic release: operates unbalanced single-phase currentat 40% and more than )(tripping time delay 4s±10%),as defined by IEC60947-4.1
4. Load indication : Flashing more than Ir setting threshold
5. Fault indication
LEDs indicates the type of fault that caused tripping
Overload (LT protection) or abnormal component temperature (>Ir);
Short-circuit (ST or instantaneous protection)( >Im);
Phase failure (right LED);
Microprocessor malfunction ( (>Ir) ( >Im) and phase failure LEDs all go on )
Battery powered. Spare battery are supplied in an adapter box. When a fault occurs ,the LEDindicating the type of fault ,lights for about 10 minutes . The information is however stored inmemory . The LED can be illuminated by pressing the test pushbutton. The LED automatically goes off and the memory is cleared when the circuit breaker is reset .
