LV HRC fuse-switch-disconnectors

Product catalog summary
Introduction
NH fuse-switch disconnectors are essential components in building installations, switchgear, controlgear, and power utility networks. They ensure safe load break operations using fuse-links as moving contacts, designed to be finger-safe when closed and provide a visible isolating distance when open. Various mounting options are available to accommodate different applications.
Product Definition
According to EN60947-3, NH fuse-switch disconnectors consist of single or multipole NH fuse-bases arranged horizontally with a common fuse-carrier. They feature accessible incoming and outgoing contacts with terminals for cable or bar connections, and busbar-mounted devices are designed for mechanical and electrical connections to standardized systems.
Applications
The compact design of these disconnectors makes them ideal for low voltage distribution panels, protective devices on standardized busbar systems, and meter protection in buildings. They are also used for UPS battery protection, telecom power supplies, and as interfaces between supply networks and decentralized power generators.
Product Advantages
JEAN MÜLLER offers a range of NH fuse-switches in sizes 000 to 4a, available in single to four-pole designs. This wide product range allows for tailored solutions in terms of current rating, voltage rating, and installation mode.
Technical Features
Products with rated currents of 400A and above include Q-contacts for quasi-independent operation, ensuring high short-circuit capability and safe load-break operations. Busbar-mounted NH fuse-switches without separate adapters have low power loss due to short connecting bars.
Versions and Accessories
Monitoring components enable remote monitoring of switch positions and fuse-links. Special executions allow size 00 fuse-switches up to 800A, providing significant space savings. Non-standard executions with divided bases are available for quick exchange without cable disconnection. Disconnectors up to 1200V offer protection for solar power installations.
Specifications
The document outlines specifications for switching devices rated up to DC 250V, including minimum space requirements for fuse protection up to 800A with LTT size 00. Devices are available in versions for baseplate and busbar mounting, as well as rear-side feeding.
Product Variants
Various NH-Sicherungslasttrennschalter (LV HRC fuse-switch-disconnectors) are listed for different applications, including telecom power supply and baseplate mounting. Details on the number of poles, terminal versions, connection sizes, and rated currents for each variant are provided.
Technical Data
The technical data section provides electrical ratings for different types of fuse-switch-disconnectors, including rated operational voltage, current, frequency, insulation voltage, and power loss. It also specifies utilization categories and impulse withstand voltage.
Accessories
A comprehensive list of accessories is provided, including clip terminals, prism clamps, switch position indicators, mechanical fuse monitors, protective covers, and electronic monitoring units, each detailed with size, type, and order number.
Special Versions
Special versions of the disconnectors are described, such as those with steel plate chassis for high protection levels (up to IP54) and versions with nickel-plated contacts for aggressive environments.
Installation and Usage
Instructions for installation, including the use of angle brackets for direct installation in front panel cut-outs, are provided. The document also mentions the use of disconnectors with screw-type slide isolating distances for neutral conductor disconnection according to national standards.
Technical Specifications Overview
  • Rated Operational Voltage: Varies across types, with AC up to 690V and DC up to 440V.
  • Rated Operational Current: Ranges from 160A to 1600A depending on the type.
  • Rated Frequency: 40-60 Hz for all types.
  • Rated Insulation Voltage: Consistently AC800V across types.
  • Rated Impulse Withstand Voltage: 8 kV for all types.
  • Utilization Categories: Includes AC-22B and DC-21B/22B with varying voltage and current ratings.
  • Rated Conditional Short-Circuit Current: Typically 50 kA, with some types supporting up to 80 kA.
  • Max Permissible Power Loss per Fuse-Link: Ranges from 9W to 164W depending on the type.
Mechanical Specifications
  • Cable Terminal: Flat terminal with bolt diameters ranging from M8 to M16.
  • Clamping Cross-Section: Varies with type, supporting different conductor sizes.
  • Tightening Torque: Ranges from 2.6 Nm to 60 Nm depending on the component.
Operating Conditions
  • Ambient Temperature: -25°C to +55°C, with reduced operating current at higher temperatures.
  • Mounting Position: Vertical and horizontal.
  • Altitude: Up to 2000 meters.
  • Pollution Degree: 3.
  • Overvoltage Category: III.
Additional Notes
  • Consider rated diversity factors according to EN 60439-1 when mounting multiple units.
  • Data are valid for 3-pole versions unless specified otherwise.
  • Type tested with LV-HRC-fuse-links characteristic gG.
Conclusion
NH fuse-switch disconnectors provide versatile and safe solutions for various electrical applications, with a range of sizes and mounting options to meet specific needs. JEAN MÜLLER offers a range of fuse-switch-disconnectors tailored to various customer applications, emphasizing robust design and adaptability to challenging conditions.
