4.Installation Conditions
1) Ambient air temperature
Considering the excessive ambient temperature to accelerate the aging of plastic parts, the upper limit is not more than +40 °C.
Considering that the excessively low ambient temperature excessively changes the fit of the structural member, the lower limit is generally not lower than -5 °C.
Considering the service life of the circuit breaker, the average value of 24 hours is not more than +35 °C.
Note: 1 The working condition of the lower limit value is -10 °C or -25 °C. The user needs to declare to the company when ordering.
2 The working condition of the upper limit value exceeding +40 °C or the lower limit value lower than -25 °C, the user needs to negotiate with the company.
2) Installation location
The altitude does not exceed 2000m;
Protection circuit requirements;
The installation point calculates the short-circuit current IK not greater than 10000A;
3) Atmospheric conditions
The relative humidity of the atmosphere does not exceed 50% at ambient air temperature +40 ° C. It can have a higher relative humidity at lower temperatures. The monthly average maximum relative humidity of the wettest month is 90%, and the average minimum temperature for the month is +25 ° C and take into account condensation on the surface of the product due to temperature changes.
4) Pollution level
The pollution level is level 3.
5) Installation category
The circuit breaker protection circuit is installed in category III.
6) The wire cross section is configured according to the maximum agreed heating current Ith of the circuit breaker.
