Fuse disconnect switch 630A, size 3, 3-pole plate mounting, FCL version with box terminals XNH3-FCL-A630-BT 183074

Fuse disconnector – reliable installation protection

This three-pole fuse disconnector, designed to work with NH3 fuse links with a current of 630A, is a solid solution for installations requiring high reliability and safety. Plate mounting ensures stability and easy integration with existing infrastructure. The FCL version with box terminals facilitates cable connection, and the built-in fuse link status control allows for quick identification of potential failures.

Functionality and application

The XNH3-FCL-A630-BT disconnector is designed to protect circuits against overload and short circuit. Its construction based on NH3 fuse links allows for effective isolation of the damaged part of the installation, minimizing the risk of downtime. The rated continuous current of 630A makes it ideal for use in industry, commercial construction and critical infrastructure. The possibility of connecting cables from the top or bottom increases installation flexibility.

Key features and benefits

• High short-circuit strength: The rated conditional short-circuit current Iq is as high as 120kA (at 500V) or 100kA (at 690V), which guarantees resistance to sudden current surges and protects the installation from serious damage.
• Fuse status control: The built-in fuse link status control function facilitates quick diagnostics and problem location, reducing repair time and minimizing downtime.
• Flexible mounting: Plate mounting provides a high degree of freedom in arrangement and integration with existing systems.
• Box terminals: Allow for convenient and secure cable connection, ensuring low connection resistance.
• Safety of use: Meets the required safety standards, protecting both the installation and the operating personnel.
• Suitable for high voltage operation: The maximum rated operating voltage Ue AC is 690V, allowing it to be used in a wide range of applications.
• Solid construction: Made of high-quality materials ensures long-lasting and reliable operation even in harsh operating conditions.
• Frame terminal: The type of main contact connection provides a solid electrical connection.
