NH Fuse switch disconnectors

Product catalog summary

Overview
NH fuse switch disconnectors are designed for low voltage electrical systems requiring high protection against short circuits while ensuring on-load circuit disconnection and isolation. They are commonly used in switchboards, distribution systems, and OEM applications.

Standards Compliance

IEC/EN 60 947-3
VDE 0660 / part 100
IEC/EN 60 269-2-1
VDE 0636 / part 201

General Characteristics

Available in five sizes from 000 to 3, supporting currents from 100A to 630A.
Uniformity and modularity across the range.
Sizes 00 and 1 offer single to quadruple pole models.
Mounting options include DIN rail, base, or busbar mounting.
Installation flexibility allows for vertical or horizontal positioning for sizes 00, 1, and 2.
Constructed from self-extinguishing, halogen-free materials.

Structure

Base: Made from glass fiber-reinforced, thermally stable, self-extinguishing synthetic material free of halogen. Copper contacts are galvanically coated, and contact springs are stainless steel.
Cover: Made from glass fiber-reinforced, self-extinguishing thermoplastic material free of halogen, with large windows for visibility and an ergonomic handle for easy operation.

Technical Specifications

Conventional free air thermal current with fuse links ranges from 160A to 630A.
Maximum allowed power dissipation varies by size and type of link.
Rated operational voltage is 690V, with a rated insulation voltage of 1000V.
Rated impulse withstand voltage is 8 kV for NH 00 and 12 kV for other sizes.
Degree of protection is IP20, with uninterrupted duty rating.
Short-circuit making capacity varies by size and type of link.

Installation and Connection

Touch protection is maintained at IP20 even in test mode.
Locking and sealing devices are available.
Easy installation by snapping onto bus bars.
Various connection options with M8, M10, and M12 screws depending on size.

References and Dimensions

Detailed references for each size and configuration, including poles, current ratings, connection types, and weights.
