The NDM3A-630 molded case circuit breaker (hereinafter referred to as circuit breaker) appliesto infrequent switching of circuits with the AC 50\/60Hz, the working voltage of AC1000V and working current of 630A as well as infrequent motor starting. With the overload, short circuit and undervoltage protection functions, the circuit breaker can protect lines and power equipment from damage.<\/p>\n\n\n\n

Normal Working Environment<\/strong>
1)The altitude of the installation site doesn\u2019t exceed 2,500m. See the \u201cHigh-altitude DeratingFactor Table of Circuit Breaker\u201d for the derating factor at the altitude;
2)The ambient temperature is -35\u2103 ~ + 70\u2103; the average within 24 h shall not be morethan +35\u2103. If the ambient temperature is higher than +40\u2103, the user needs to reduce thecapacity. See the \u201cDerating Factor Table of Temperature Change for the Circuit Breaker\u201dfor the derating factor;
3)Its relative humidity at an ambient temperature of +40\u2103 should not exceed 50%. A higherrelative humidity is allowed at a lower temperature. For example, the relative humidity at20\u2103 can reach 90%; for frost due to temperature change, the corresponding measuresshould be taken;
4)The product can withstand the effects of wet air, salt mist, oil mist and mould;
5)The installation category of the circuit breaker connected to the main loop is: Category \u2162 (power distribution and control level), The installation category of the circuit breaker notconnected to the main loop is: Category \u2161 (load level);
6)The pollution level is Level 3;
7)The product should be installed in places that are free from explosive media, mediacorrosive to metal, insulation damaging gas, and conductive dust, which should be alsoavoided from snow and rain;
8)In case of stricter user conditions than the above description, negotiate with themanufacturer.<\/p>\n\n\n\n
