Siemens 3NA38247 NH Fuse Size 00, 80A, 500V AC

The Siemens 3NA38247 is a professional-grade NH fuse link engineered for robust electrical protection in industrial environments. Designed in the compact size 00 format, this fuse is rated for 80A and operates efficiently at 500V AC. It serves as a critical component in electrical distribution systems, ensuring safety by interrupting circuits during short-circuit or overload conditions. The device features non-insulated grip lugs and follows the gG characteristic class, which is the standard for general-purpose cable and line protection.

Advantages

This fuse link offers exceptional reliability and consistent performance under demanding industrial conditions. Its gG characteristic ensures a wide range of protection, covering both low-overload and high-short-circuit currents. The compact size 00 design allows for space-saving installation within standard fuse bases, while the high-quality construction materials ensure long-term stability and durability in power distribution networks.

Suitable for

• General-purpose electrical distribution systems
• Industrial machinery and equipment protection
• Cable and line protection in low-voltage networks
• Control panels and switchgear assemblies

When it may not be suitable

This fuse is not intended for use in DC circuits or high-voltage applications exceeding 500V AC. It is also not suitable for specialized applications requiring fast-acting or ultra-rapid fuse characteristics, such as protecting sensitive power semiconductors.

Key specifications

• Fuse size: 00
• Rated current: 80A
• Rated voltage: 500V AC
• Characteristic class: gG
• Grip lugs: Non-insulated

How to use

The fuse should be installed into a compatible NH size 00 fuse base or disconnect switch. Ensure that the power supply is completely disconnected before attempting to insert or replace the fuse. Use an appropriate insulated fuse handle or puller to safely insert the fuse into the base, ensuring that the grip lugs are fully seated and secure. Verify that the electrical circuit is properly de-energized before performing any maintenance.

What to consider before purchase

• Verify that the fuse base size matches the 00 format
• Ensure the 80A rating is appropriate for the specific circuit load
• Confirm that the system voltage does not exceed 500V AC
• Check if non-insulated grip lugs are compatible with your existing safety equipment

Usage recommendations: Always replace fuses with the exact same rating and characteristic class to maintain system safety. It is recommended to inspect the fuse base for signs of oxidation or heat damage during every replacement cycle.
