Fuse disconnect switch NH00 3P 160A LVSG00SPX

Strip fuse disconnect – reliable installation protection

This three-pole NH00 strip fuse disconnect with a rated current of 160A is a key element of every safe and efficient electrical installation. Designed to work with NH00 fuses, it provides effective protection against overloads and short circuits, minimizing the risk of damage and downtime. Solid construction and high-quality workmanship guarantee long-lasting and trouble-free operation.

Construction and mounting

The disconnect is designed for mounting on rails with a spacing of 185mm, which facilitates its integration with existing systems. It has M8 screw connections, providing a secure and durable connection of cables with a cross-section from 2.5 to 95 mm². Electrical endurance at 200 cycles and mechanical endurance at 1400 cycles demonstrate its reliability in heavily used installations. Protection class IP2X protects against touching live parts and the ingress of solid objects larger than 12.5 mm.

Parameters and application

The device is characterized by a rated operating voltage of up to 690V AC and a rated conditional short-circuit current Iq of 120 kA. The rated continuous current Iu is 160A, making it an ideal solution for circuits requiring protection against high loads. The possibility of connecting copper and aluminum wires increases its versatility. Thanks to this, the disconnect finds application in:

• Power distribution boards: Provides safe disconnection of power circuits.
• Industrial installations: Protects machines and equipment from damage caused by overloads or short circuits.
• Commercial buildings: Secures electrical installations in offices, shops and other public utility facilities.
• Photovoltaic systems: Can be used as a protective element in solar installations (check compliance with local regulations).
• Applications requiring high reliability: Guarantees stable operation of critical electrical systems.

Compliance with standards ensures safe use and a guarantee of correct operation in various working conditions (ambient temperature from -25°C to +55°C). A Polish-language installation manual is available, making proper installation of the device easier.
