Product information

Description

The Siemens 3NA3260 is a high-performance NH safety fuse engineered to provide robust electrical protection in industrial environments. Rated for a current of 400A and a voltage of 500V, this size 2 fuse is designed to handle demanding electrical loads while ensuring the safety of distribution systems. It features gG class characteristics, which offer comprehensive protection against both overloads and short circuits, making it a reliable component for maintaining operational continuity in critical infrastructure.

Advantages

This safety fuse stands out due to its high breaking capacity and reliable performance under varying electrical conditions. The gG class classification ensures that the device responds effectively to a wide range of fault currents, protecting sensitive equipment from damage. Its standardized size 2 design allows for seamless integration into existing electrical panels and fuse bases, while the non-insulated contact construction ensures a secure and stable connection within industrial switchgear assemblies.

Suitable for

Industrial electrical distribution systems
Protection of power cables and electrical equipment
Switchgear and control gear assemblies
Heavy-duty manufacturing machinery

When it may not be suitable

This fuse is not intended for use in low-voltage residential applications where smaller fuse formats are typically required. It is also not suitable for direct current (DC) applications unless specifically rated for such use, as its primary design is optimized for alternating current (AC) industrial networks.

Key specifications

Rated current: 400A
Rated voltage: 500V
Fuse size: 2
Operating class: gG
Contact type: Non-insulated

How to use

The Siemens 3NA3260 should be installed by qualified personnel into a compatible NH size 2 fuse base. Ensure that the power supply is completely disconnected before attempting installation or replacement. Align the fuse blades with the contact clips of the fuse base and press firmly until it is securely seated. Always verify that the fuse rating matches the requirements of the circuit to prevent improper protection.

What to consider before purchase

Verify that the fuse base is compatible with size 2 NH fuses.
Ensure the 400A current rating matches your circuit protection requirements.
Check that the 500V voltage rating is sufficient for your electrical system.
Confirm that non-insulated contacts are appropriate for your specific installation environment.

Usage recommendations

Always replace fuses with units of the same type and rating to maintain the integrity of the electrical protection system. Periodic inspection of the fuse contacts for signs of oxidation or overheating is recommended to ensure long-term reliability.
