NSX400N MCCB/3P

Short Description:

Normal work and installation conditions

1. The altitude of the installation site does not exceed 2000m;

2. The JNS thermomagmetic type with temperature of the surrounding medium is -5C~+40C, and the average temperature of 24h is not more than +35C. The relative humidity of the air at the installation site does not exceed 50% at a maximum temperatureof +40°C ; at lower temperatures, there may be a higher relative humidity; the average minimum temperature of the wettest monthdoes not exceed +25C for the average of the month The maximum relative humidity is not more than 90%, and the condensationon the surface of the product due to temperature changes is considered.

3. JNS intellgent type with temperature of the surrounding medium is -40C~+80C

4. The product is used in non-explosive hazardous media, and the media does not have enough to corrode metals and destroyinsulating gases and conductive dust.

5. In places where there is rain protection and no water vapor.

6. The installation category is Class Ill.

7. The pollution level is level 3.

8. The basic installation of the circuit breaker is vertical (ie vertical) or horizontal (ie horizontal).

9. The incoming line is either the up line or the down line.

10. Circuit breakers can be divided into fixed and plug-in types.
