Fuse disconnect switch 250A, size 1, 1-pole plate mounting, Basic version XNH1-1-A250 183049

Fuse disconnect switch – reliable installation protection

This single-pole fuse disconnect switch, with a rated current of 250A, is designed for plate mounting. It is a key element in electrical protection systems, providing effective protection against overloads and short circuits. The construction based on proven Eaton solutions guarantees long-term and trouble-free operation.

Construction and application

The XNH1-1-A250 disconnect switch from the XEFFECT series is designed to work with NH1 type fuse links. Its solid construction and compact dimensions allow for easy mounting in distribution boards and control cabinets. It is intended for disconnecting electrical circuits in emergency situations or during maintenance work. Screw connection provides a secure and durable connection of wires. The device is characterized by high short-circuit strength, amounting to 120 kA at 500V or 100kA at 690V, which makes it an ideal choice for installations exposed to current surges.

Key features and benefits

• High resistance to working conditions: Rated operating voltage up to 690V AC makes the disconnect switch usable in a wide range of industrial and commercial applications.
• Safety of use: Provides effective protection against overload and short circuit – like most circuit breakers in this class.
• Easy installation: Designed for plate mounting, it facilitates integration with existing electrical systems.
• Durability: Rated short-time withstand current Icw is 6kA, which confirms its ability to withstand temporary overloads.
• Versatility: Compatible with NH1 fuse links, providing a wide selection of protective elements.
• Solid connections: Screw connection guarantees a secure and durable connection of wires with a cross-section of up to 150mm².
• Possibility of blown fuse indication: Available versions with blown fuse indication (optional), which facilitates quick problem identification.
