Fuse disconnect switch 630A, size 3, 3-pole plate mounting, Basic version XNH3-A630 183071

Fuse disconnect switch – reliable installation protection

This three-pole fuse disconnect switch with a rated current of 630A is a solid solution for protecting electrical circuits. Designed to work with NH3 fuse links, it provides effective protection against overloads and short circuits. Plate mounting simplifies integration with existing electrical infrastructure, and its construction guarantees durability and reliable operation.

Design and application

The disconnect switch is designed for plate mounting, making it an ideal choice in situations where space is limited or flexible component placement is required. Made of high-quality materials, it ensures long-term operation even in demanding conditions. Screw connection of the main contacts guarantees a secure and stable connection of the conductors. A continuous rated current of 630A makes it suitable for protecting circuits with high power consumption. Withstood short-circuit current of 3kA and a high rated conditional short-circuit current (120kA at 500V or 100kA at 690V) demonstrate its ability to cope with sudden current surges.

Advantages and benefits

• High short-circuit strength: Provides protection for the installation even in the event of serious power disturbances.
• Plate mounting: Allows flexible placement and easy integration with existing systems.
• Rated current 630A: Ideal for protecting circuits with high power consumption.
• Compatible with NH3 fuse links: Standard fuse link type, readily available on the market.
• Screw connection: Guarantees a secure and durable connection of the conductors.
• Operating voltage up to 690V AC: Wide range of operating voltages increases versatility.
• Possibility of connecting conductors from above or below: Facilitates mounting and connection in various installation configurations.
• Option of fuse blown indication: Allows for quick identification of a damaged fuse (available in some versions).

This disconnect switch is a solid choice for both professional installers and end-users looking for reliable electrical protection. Its robust construction and high technical parameters guarantee long-lasting and trouble-free operation.
