Fuse disconnector NH SPX3-V 1 2500 A 605851

Strip fuse disconnect switch – reliable protection and comfortable work

NH SPX3-V 1 fuse disconnect switch with a current of 250 A is a solid solution for safely disconnecting electrical circuits. Designed with the needs of both professional installers and end-users in mind, it provides effective protection of the electrical installation against overloads and short circuits. It is a key element in power distribution systems, guaranteeing safety and continuity of supply.

Construction and application

The construction of the disconnect switch is based on the NH1 standard, which means compatibility with a wide range of fuse cartridges. The three-pole design (3 poles) allows disconnecting all phases simultaneously, providing complete circuit isolation. The rated continuous current of 250 A and the short-circuit breaking capacity of up to 120 kA make the device perfect for installations with high load. The possibility of mounting on a 185 mm busbar system (5 or 10 mm) facilitates integration with the existing infrastructure. It finds application in power distribution boards, control cabinets and wherever safe disconnection of circuits under load is required.

Key features and benefits

• Safety first: Compliance with IEC/EN 60947-3 standard guarantees a high level of safety.
• Ease of use: The ability to lock the cover with a padlock prevents accidental opening and provides additional security. The transparent cover allows for a quick visual check of the fuse cartridge status without having to open the disconnect switch.
• Universal mounting: Mounting on 185 mm busbars and the possibility of using bridge or prismatic terminals (available as accessories) ensure installation flexibility.
• Durability and reliability: Construction adapted for frequent use – up to 1600 switching operations.
• Status indication: The possibility of connecting a cover position indicator (accessory) informs about the current status of the disconnect switch.
• High rated power: The rated power for AC-23, 400 V is as high as 173 kW, making it an ideal solution for demanding industrial applications.
• IP40 protection class: Provides protection against the ingress of solid objects larger than 1 mm, which increases the durability of the device in harsh working conditions.
• Easy connection of wires: Busbar connection facilitates and speeds up the process of connecting wires with crimp terminals.

Remember! Fuse cartridges must be purchased separately – select them appropriately for your installation needs!
