Fuse disconnect switch – reliable installation protection

This three-pole NH00 fuse disconnect switch, with a rated current of 160A, is a key element of any electrical installation requiring effective protection against overloads and short circuits. Designed to work with NH00 type fuses, it provides quick and safe circuit isolation in the event of a failure. The design adapted for mounting on 60mm rails makes it easy to integrate with existing distribution systems.

Construction and mounting

The disconnect switch is characterized by a solid construction and compact dimensions (106 mm wide, 104 mm deep and 206 mm high). Prismatic screw terminals allow connection of copper and aluminum conductors with a cross-section of up to 70 mm², ensuring a stable electrical connection. Mounting on rails is quick and easy, which translates into time savings during installation. Additionally, the sealable locking mechanism prevents accidental switching on after switching off for maintenance or repair.

Safety and compliance with standards

The device has a protection degree of IP3X, which means protection against access to live parts and protection against the ingress of solid objects larger than 2.5 mm. It meets the requirements of IEC 60947-3 and VDE 0660-107 standards, guaranteeing high quality and safety of use. The rated insulation voltage Ui is 1000V, and the maximum AC operating voltage is 690V, making it suitable for use in medium voltage networks. The built-in fuse insert status control informs about the need to replace a blown fuse, increasing work safety.
