NH disconnector, size 000, 3x100A, mounted on TH35 rails LT0050

Fuse disconnect switch – reliable circuit protection

This three-pole NH-size 000 disconnect switch, with a rated current of 100A, is a key element of any electrical installation requiring safe disconnection of power circuits. Designed for mounting on TH35 rails, it provides convenient and quick installation for both professionals and end-users. The switch design allows for easy replacement of the NH000 fuse insert, simplifying servicing and minimizing downtime.

Construction and application

The disconnect switch is designed to work with NH000 fuse inserts, providing effective protection against overloads and short circuits. Its compact dimensions (width 53 mm, height 216 mm, depth 82 mm) allow for mounting in switchboards with limited space. The rated insulation voltage Ui of 1000 V and the maximum operating voltage Ue AC up to 690 V guarantee safe use in a wide range of industrial and commercial applications. The IP3X degree of protection prevents access to live parts and provides basic protection against environmental influences.

Key features and benefits

• Versatility: Ideal for use in residential, commercial and light industrial applications.
• Safety: Provides effective protection against overloads and short circuits thanks to cooperation with NH000 fuse inserts.
• Easy installation: Designed for quick mounting on standard TH35 rails.
• High quality workmanship: Guaranteed by a reputable manufacturer – Hager.
• Status transparency: Lack of fuse status control requires visual inspection after circuit disconnection – standard practice for this type of switch.
• Solid construction: Durable housing ensures long-lasting and reliable operation of the device.
• Cage clamps: Allow connection of wires with a cross-section of up to 50mm², ensuring a secure electrical connection (information from additional sources).

This disconnect switch is invaluable wherever reliable disconnection of electrical circuits is required with the ability to protect them from the effects of short circuits and overloads. It is an integral part of electrical power distribution systems, ensuring safety of use and protection of the installation.
