Fuse disconnect switch 250A, size 1, 3-pole mounting on Sasy 60i, FCL version with box terminals XNH1-FCL-S250-BT 183054

Fuse disconnect switch – reliable installation protection

This three-pole fuse disconnect switch, designed to work with NH1 fuse links, is a key element in protecting the electrical installation. Designed for mounting on SASY 60i rails, it offers a solid construction and high resistance to working conditions. The FCL version with box terminals provides convenient and safe connection of wires.

Functionality and technical parameters

The device is characterized by a continuous rated current of 250A and a high short-circuit strength – 120kA at 500V or 100kA at 690V. The use of characteristic C allows it to react more slowly to short current surges, therefore it tolerates the starting of devices with a motor well. The disconnect switch has a built-in fuse link status control, which facilitates quick identification of any failures. The possibility of connecting wires from the top or bottom increases installation flexibility. Made of high-quality materials, it ensures long-lasting and trouble-free operation.

Application and benefits

• Versatility: ideal for use in electrical switchboards, control cabinets and other installations requiring reliable protection against overload and short circuit.
• Safety: protects the circuit against overload and short circuit — like most circuit breakers in this class.
• Blown fuse indication: optical indication of a blown fuse link facilitates quick problem location and minimizes installation downtime.
• Installation: designed for easy mounting on SASY 60i rails, which speeds up the installation process and reduces labor costs.
• Durability: high short-circuit strength guarantees reliable operation even in difficult operating conditions.
• Connection flexibility: the possibility of connecting wires from the top or bottom adapts to different installation configurations.
• Box terminals: provide a secure and durable connection of wires with a cross-section of up to 150 mm².
• Fuse status control: the fuse link status control function increases safety and facilitates diagnostics.

This disconnect switch is a solid solution for both professional installers and end-users looking for reliable protection of their electrical installations.
