NH SPX2 400A fuse disconnector on base 605206

Fuse disconnect switch – reliable installation protection

The NH SPX2 400A fuse disconnect switch is a component used to safely disconnect electrical circuits and protect against overloads and short circuits. Designed to work with NH2 type fuse links, it provides effective insulation and control over current flow. The design allows for panel mounting, making it easy to integrate with existing electrical systems. The device is particularly useful in industrial applications and public buildings where high reliability and safety are required.

Construction and application

This disconnect switch is characterized by a solid construction and high quality workmanship. Frame terminals ensure a secure connection of wires, and the IP40 degree of protection guarantees resistance to external factors. Designed to operate at a maximum voltage of 800V AC, it works perfectly in medium and high voltage installations. Its main task is to ensure safe disconnection of the circuit in the event of a failure or the need to perform maintenance work. Thanks to this, both installers and end users can be sure of safe use.

Key features and benefits

• High rated continuous current (Iu = 400A): allows protection of circuits with high power consumption, which is important in industrial applications.
• Rated conditional short-circuit current (Iq = 50kA): provides effective protection against the effects of short circuits, minimizing the risk of damage to installations and equipment.
• Possibility of panel mounting: facilitates integration with existing electrical systems, saving time and installation costs.
• Type of connection of the main contacts – frame terminal: guarantees a secure and durable connection of wires, minimizing the risk of loosening connections.
• Safety disconnect and main switch function: provides comprehensive protection of the electrical installation, meeting safety standards.
• Intended for NH2 fuse links: compatibility with popular NH2 fuse links facilitates replacement and servicing of the device.
• Rated operating power for AC-23, 400 V (276.8 kW): allows use in circuits powering high-power devices, such as electric motors or industrial heaters.
• Location of the drive element on the front side: facilitates operation and control of the disconnect switch status.

Thanks to these features, the SPX2 400A disconnect switch is a reliable solution for professionals and users looking for high-quality electrical protection.
