Schneider NS800N Breaker

Applications

The Schneider NS800N circuit breaker is intended for low-voltage electrical distribution applications where reliable circuit interruption and protection are important. It may be considered for industrial power systems, commercial electrical installations, and distribution assemblies, provided its complete electrical configuration meets the application requirements.

Typical application scenarios include:

• Industrial distribution systems: Integration into suitable power distribution panels in manufacturing facilities.

• Main switchboards: Use in incoming or outgoing feeder arrangements where the breaker's ratings are appropriate.

• Commercial buildings: Application in electrical distribution systems serving large buildings and infrastructure.

• Electrical equipment protection: Protection of feeders and connected equipment against specified overcurrent conditions.

• Maintenance and replacement projects: Sourcing as a replacement component after confirming compatibility with the installed equipment.

Advantages

The Schneider NS800N offers a solution for low-voltage distribution applications requiring a dedicated circuit protection device. Its suitability for a particular installation depends on the exact product version and configuration.

• Industrial distribution use: Suitable for consideration in appropriately rated industrial and commercial electrical systems.

• Integration flexibility: Can be incorporated into compatible switchboards and distribution assemblies.

• Configuration verification: The complete product reference helps identify the required breaker version and accessories.

• Maintenance support: Can be included in spare-parts planning for electrical equipment maintenance and replacement.

Technical FAQs

Q1: What is the main purpose of the Schneider NS800N circuit breaker?

A: It is designed to protect low-voltage electrical circuits by interrupting current under specified fault conditions. Its actual protection functions depend on the installed trip unit.

Q2: What types of electrical faults can the NS800N protect against?

A: Depending on the fitted protection release, the breaker may provide overload and short-circuit protection. The exact functions should be confirmed from the trip unit documentation.

Q3: How can I confirm whether the NS800N is suitable for my electrical system?

A: Compare its rated current, operational voltage, breaking capacity, pole configuration, trip unit, and connection arrangement with the system design and installation requirements.

Q4: What is the difference between rated current and breaking capacity?

A: Rated current refers to the current the breaker is designed to carry under specified conditions. Breaking capacity indicates the maximum prospective fault current it can interrupt under defined test conditions.

Q5: Does the NS800N require a separate trip unit?

A: The protection configuration depends on the specific breaker version. Check the complete catalog reference and product documentation to determine the supplied trip unit arrangement.

Q6: Can the NS800N be integrated into an automated electrical control system?

A: Monitoring and control integration may be possible with compatible auxiliary contacts or operating accessories. The available functions depend on the installed configuration.

Q7: What should be checked when wiring the circuit breaker?

A: Confirm the terminal arrangement, conductor specifications, connection torque, phase sequence where applicable, and installation instructions. All work should be performed by qualified electrical personnel.

Q8: Can the NS800N be used in a system with high short-circuit current?

A: Its suitability depends on the verified breaking capacity at the system's operating voltage and the prospective short-circuit current at the installation point.

Q9: What maintenance is recommended for the NS800N?

A: Follow the manufacturer's maintenance instructions. Checks may include terminal condition, connection tightness, operating mechanism, trip unit, accessories, and evidence of overheating or physical damage.

Q10: Why should the complete catalog number be checked before purchasing?

A: Different configurations may have different trip units, accessories, connection arrangements, or electrical ratings. Checking the full reference helps avoid ordering an incompatible version.
