NF1250-SEW塑壳断路器 英文介绍

Introduction to Mitsubishi NF1250-SEW Molded Case Circuit Breaker

NF1250-SEW is a high-capacity molded case circuit breaker (MCCB) belonging to Mitsubishi Electric's NF series, used for main circuit protection in low-voltage distribution systems.

This series is known for its high breaking capacity, stability, reliability, and strong adaptability. It is commonly used in industrial power systems, factory distribution cabinets, and main protection circuits for high-power equipment.

The "1250" in the model indicates that the shell level current of the circuit breaker is 1250A, which can meet the protection requirements of medium and large load circuits.

Main Features

Large capacity protection capability: Suitable for high current circuits, it can protect loads and distribution lines from overload and short circuit damage.

High breaking capacity design: capable of withstanding high current fault conditions, suitable for high demand industrial environments.

Durable and sturdy structure: Made of industrial grade materials, it has a long mechanical and electrical lifespan.

Flexible release configuration: SEW models are usually equipped with electronic release units, which can be set for long delay, short delay, and instantaneous protection.

Easy to install: Supports panel or cabinet installation, suitable for various distribution system architectures.

Excellent safety performance: equipped with insulation protection and anti contact design, enhancing equipment and personnel safety.

Typical technical parameter range (NF1250 standard reference)

The actual parameters may vary slightly due to the specific configuration of the trip unit, and the following are common ranges:

Shell level current: 1250A

Rated current: adjustable according to the setting range of the release device

Pole number: commonly 3 poles (3P)

Release unit: electronic (long delay/short delay/instantaneous adjustable)

Rated voltage: generally low voltage AC (such as AC400/690V)

Breaking ability: Depending on the version, it may have a medium to high breaking level

Installation method: panel installation or bolt fixed installation

Application: Main incoming line, segmented protection, high-power equipment circuit protection

Typical Applications

Factory main distribution cabinet

Main power protection for large-scale production equipment

Distribution system segmentation/feeder protection

Low voltage distribution system for commercial and industrial buildings

Power protection for high-power motors, compressors, and pumps
