Fuse disconnect switch 630A, size 3, 3-pole plate mounting, FCL version XNH3-FCL-A630 183073

Fuse disconnect switch – reliable installation protection

This three-pole fuse disconnect switch, designed to work with NH3 fuse links, is a solid solution for installations requiring high reliability and safety. Plate mounting makes it ideal for building switchboards and control cabinets. The XNH3-FCL-A630 model from Eaton Electric guarantees protection against overloads and short circuits in circuits with a current of up to 630A.

Design and application

The disconnect switch is designed for plate mounting, which simplifies its integration with various types of enclosures. Made of high-quality materials, it provides durability and resistance to environmental conditions. It is intended for protecting electrical circuits in public buildings, industrial plants and energy infrastructure. The use of an NH3 fuse link allows for a quick response in the event of a failure and minimizes the risk of damage to the installation. Checking the status of the fuse link provides additional peace of mind – you immediately know if the protection is active.

Key features and benefits

• High short-circuit strength: The disconnect switch can withstand short-circuit currents up to 120kA (at 500V) or 100kA (at 690V), which ensures effective protection even in the event of serious disturbances in the network. This is crucial for ensuring continuity of supply and minimizing downtime.
• Rated current 630A: Allows protection of circuits with high power consumption, ideal for advanced electrical installations.
• Plate mounting: Simplifies integration with existing switchboards and control cabinets, saving time and installation costs.
• Blown fuse indication: Built-in indication informs about the need to replace the fuse link, which increases safety and facilitates maintenance.
• Screw connection: Provides a secure and durable connection of electrical wires. The possibility of connecting wires from above or below increases installation flexibility.
• Voltage universality: Adapted to work at AC voltage up to 690V and DC voltage up to 440V – a wide range of applications.
• Solid construction: Made of durable materials guarantees long life and reliable operation even in difficult operating conditions.
• Actuator element – cover handle: Provides convenient operation of the disconnect switch when replacing the fuse link or performing maintenance work.

This disconnect switch is not only a protective element, but also an investment in the long-term and trouble-free operation of the entire electrical installation.
