Product information

Description

The Siemens LV HRC fuse NH3 630A gG 500Vac/440Vdc is designed for reliable electrical circuit protection in demanding industrial environments. As part of the Siemens SENTRON series, this fuse link ensures safe and selective system and line protection by securely interrupting overloads and short-circuit currents. It features a robust NH3 size configuration with a rated current of 630 amperes and operates under a gG operating class, making it suitable for general industrial power distribution applications.

Advantages

This Siemens LV HRC fuse provides dependable safety for personnel, equipment, and electrical lines by ensuring reliable disconnection during fault conditions. Built to high manufacturing standards, it delivers consistent performance in industrial power distribution and switchgear setups. The front indicator allows for quick and clear status identification during maintenance checks, minimizing system downtime.

Suitable for

  • Industrial power distribution networks
  • Switchgear and control gear assemblies
  • Line and system protection in electrical infrastructures

When it may not be suitable

This fuse is not designed for residential electrical installations or low-voltage household appliances. It is also unsuitable for circuits operating outside its specified voltage and current ratings.

Key specifications

  • Rated current: 630 A
  • Size: NH3
  • Operating class: gG
  • Rated voltage AC: 500 V
  • Rated voltage DC: 440 V
  • Indicator type: Front indicator
  • Grip type: Live grip lugs (non-insulated)

How to use

Installation should be performed exclusively by qualified electrical personnel following standard safety regulations and procedures. Ensure the electrical circuit is completely de-energized before handling or replacing the fuse link. Insert the fuse securely into a compatible NH3 fuse base using appropriate insulated handling tools designed for live-grip applications, making sure the front indicator is visible for future inspections.

What to consider before purchase

  • Verify that the rated current of 630A matches your system requirements
  • Confirm that the physical size NH3 fits your existing fuse holder
  • Check that your system operating voltage does not exceed 500V AC or 440V DC
  • Ensure proper safety gear and handling tools are available for installation

Usage recommendations

Always replace blown fuses with identical models matching the exact current rating, size, and operating class. Periodic inspection of fuse contacts and holders is recommended to prevent resistive heating and ensure optimal electrical performance.
