Schneider universal circuit breaker NS series model parameters and characteristic requirements

Brief overview of Schneider universal circuit breaker NS series

The Compact NS series universal circuit breaker adopts a modular system design, which indirectly promotes the standardization of the power distribution cabinet, and the installation is quick and easy to make mistakes. All circuit breakers from NS630b to 1600A have only one external dimension, and they can be installed in parallel to reduce the use of space.

A variety of connection methods use accessories that can be quickly connected to the universal circuit breaker, and there are multiple connection methods, including bare cables, cable lugs or terminal posts. Choose different releases so that each Compact NS series 630b to 1600A circuit breaker can protect the following equipment or systems:

●Low-voltage power distribution;

●Generator;

●Long cable;

●Motor;

●Special purpose.

General characteristics of Schneider universal circuit breaker NS series

◆ Meet the standards.

Compact NS630b to 1600A universal circuit breaker specifications and auxiliary equipment comply with the following international standards:

1. General provisions of IEC60947-1;

2. IEC60947-2 circuit breaker;

3. IEC60947-3 switch, isolator, isolating switch, etc.;

4. IEC60947-4 contactor and motor starter;

5. IEC60947-5.1 control equipment and switches, automatic control components.

These standards are adopted by most countries. Schneider Compact NS series universal circuit breakers and auxiliary equipment also comply with European (EN60947-1 and EN60947-2) and related international standards. The details are as follows:

6. French NF standard;

7. German VDE standard;

8. British BS standard;

9. Australian AS standard;

10. CEI of Italy.

◆ Pollution level.

The pollution degree of Schneider Compact NS series 630b to 1600A universal circuit breakers is confirmed to be level three, meeting the definition in IEC standard 60947 (industrial environment).

◆Anti-humid and heat measures.

The Compact NS series 630b to 1600A Schneider circuit breakers have passed the tests under the strict environmental conditions specified in the following standards:

●IEC68-2-1-dry cooling (-55℃);

●IEC68-2-2-dry heat (+85℃);

●IEC68-2-30-Humidity and heat (humidity and heat conditions 55℃, 95% relative humidity);

●IEC68-2-52-salt spray.

◆Ambient temperature.

1. The ambient temperature range is -25°C to +70°C, and when it is higher than 40°C (higher than 65°C for motor protection), derating should be considered;

2. It can work for a long time under normal environment, and can work in harsher environment from -25 to -35℃;

3. The storage temperature is -50℃ to +85℃, and the Micrologic control unit with LCD display is -40℃.

◆Reliable contact indication with isolation function.

The isolation function of all Schneider Compact NS series universal circuit breakers shall comply with the IEC60947-2 standard: the isolation position corresponds to "O" (OFF position), and the operating handle can indicate the "OFF" position only when the contact is really opened. The padlock can be installed only when the contacts are opened. Rotating the handle or electric mechanism will not change the reliability of the contact indication system.

Isolation function protection:

●The mechanical reliability of the contact indication system;

●No leakage current;

●Overvoltage withstand capability between terminals of incoming and outgoing wires.

◆Installation of Class II switchgear.

The NS series universal circuit breaker with rotary handle and electric mechanism can be installed in the switch cabinet of protection class II (according to the IEC60664 standard), and will not reduce the insulation level of the switch cabinet, because the NS series provides a class II insulation panel and all The internal circuit is insulated.

◆Protection level

According to the IEC60529 standard (IP entry protection level) and the EN50102 standard (IK impact resistance protection level), the specific protection level of Schneider universal circuit breakers is shown in the figure.

Schneider universal circuit breaker NS series operation requirements

◆ Altitude

The height below 2000 meters will not have any influence on the characteristics of the universal circuit breaker. If it exceeds this height, the factors of air insulation and cooling capacity must be considered. The correction factor given in the figure below is used when the installation altitude exceeds 2000 meters, and the breaking capacity of Schneider circuit breakers remains unchanged.
