Fuse disconnect switch 250A, size 1, 3-pole mounting on Sasy 60i, Basic version XNH1-S250 183051

Fuse disconnect switch – reliable installation protection

This three-pole Eaton XNH1-S250 fuse disconnect switch, designed for mounting on 60i rails, is a key element in protecting electrical installations. Designed for both industrial and public building applications, it provides effective protection against overloads and short circuits. Its robust construction and high resistance to environmental conditions guarantee long-lasting and trouble-free operation.

Features and application

The XNH1-S250 disconnect switch is compatible with NH1 type fuse links, and its rated current is 250A at 690V AC. The possibility of mounting on rails facilitates integration with existing switchboards, and the Basic version provides an optimal price-to-quality ratio. The device is used to protect circuits powering various types of receivers, such as motors, transformers or heating devices. The short-circuit strength of 120kA (at 500V) or 100kA (at 690V) ensures safety even in the event of serious disturbances in the network.

• Versatility: The ability to mount on 60mm busbars makes the disconnect switch compatible with a wide range of switchboards.
• High strength: The rated conditional short-circuit current Iq is as high as 120 kA, which guarantees reliable operation in difficult conditions.
• Simple installation: Designed for easy and quick installation, saving time and labor costs.
• Safety: Provides effective protection against overloads and short circuits, minimizing the risk of failures and fires.
• Solid connections: The use of screw connections ensures stable and reliable connection of wires.
• Blown fuse indication: An optional blown fuse indication feature makes it easier to quickly identify the problem and minimize downtime.

Construction and parameters

The XNH1-S250 disconnect switch is characterized by a solid construction ensuring high reliability and durability. Made of high-quality materials resistant to mechanical damage and environmental factors. The cover handle allows for convenient operation of the device, and the lack of a built-in motor drive simplifies the design and reduces operating costs. The rated short-time withstand current Icw is 6 kA, which further increases the safety of the installation. The lack of fuse status control means that the status of the fuse must be visually inspected by the user or service technician.

The rated continuous current is 250 A at a rated voltage of 690 V AC or 440 V DC. The rated conditional short-circuit current Iq is 120 kA at 500 V and 100 kA at 690 V. The type of connection of the main contacts is a screw connection, and the disconnect switch is intended for use with NH1 type fuse links. The device has three poles.

This disconnect switch is an ideal solution for installers looking for a reliable and easy-to-install protective device and for end users who value safety and long-lasting operation.
