Fuse disconnector 250A, size 1, 3-pole plate mounting, version FCL XNH1-FCL-A250 183045

250A fuse disconnect switch is a solid solution for protecting electrical installations, designed for both industrial and public building applications. The device is three-pole and designed for plate mounting, which simplifies integration with existing systems. The FCL version is equipped with optical indication of fuse failure, which significantly improves diagnostics and minimizes downtime.

Features and application

This fuse disconnect switch is designed to work with NH1 type fuses. The rated continuous current of 250A and high short-circuit strength (120 kA at 500V or 100kA at 690V) guarantee reliable protection of circuits against overloads and short circuits. The ability to connect cables from above or below and a wide range of cable cross-sections (up to 150 mm²) provide flexibility during installation. The fuse failure indication allows for quick identification of the damaged element, which is crucial for maintaining the continuity of the installation.

Advantages and benefits

• High reliability: Rated continuous current of 250A and short-circuit strength of 120kA ensure effective protection of the electrical installation.
• Fuse failure indication: Optical indication of the fuse status facilitates quick diagnostics and minimizes downtime.
• Installation flexibility: Plate mounting and the ability to connect cables from above or below simplify integration with various systems.
• Safety: Compliance with standards ensures safe operation of the device.
• Easy damage identification: Fuse status control allows for quick detection of problems.
• Solid construction: Made of high-quality materials guarantees long device life.
• Suitable for different cable cross-sections: Support for cables with a cross-section of up to 150 mm² provides a wide range of applications.

Design and parameters

The disconnect switch has a screw connection of the main contacts, which ensures a secure and durable electrical connection. The cover handle serves as an actuator, allowing easy switching on and off of the circuit. The device is designed to operate at a maximum voltage of 690V AC, making it suitable for a wide range of industrial and commercial applications. Additionally, the disconnect switch has a protection degree of IP20, which protects against accidental contact. The use of optical fuse failure indication (FCL version) increases the functionality of the device, enabling a quick response to failures.
